Four Decades of Community-Based Conservation in Northeast India: Nature’s Beckon, Environmental Activism, and Transferable Lessons

Abstract

Global biodiversity policy increasingly depends on community-led conservation, yet the comparative evidence base contains little from South Asia’s frontier regions. This article asks how a long-running grassroots organisation in a politically and ecologically marginal region combined community mobilisation, vernacular knowledge, scientific evidence, and engagement with public institutions in pursuing conservation outcomes, and which features of that process may be relevant beyond Northeast India. Four campaigns of Nature’s Beckon, founded in Dhubri, Assam, in 1982, are compared as distinct types of intervention: species-led protected-area mobilisation at Chakrashila; landscape-scale conservation against extractive pressure at Dihing Patkai; species research with public ecological education; and community-managed institution-building. The available evidence indicates a documented and substantial, though not exclusive, role in campaigns associated with the notification of two protected areas whose current notified areas total approximately 279.83 km². Advocacy alone does not adequately explain these outcomes: where a formal government decision was required, sustained organisational capacity became consequential only when it coincided with a favourable political and administrative opening. Measured against four design features associated with successful community-based conservation, the model corresponds strongly to capacity-building investment and external linkage, in qualified form to equitable benefit-sharing, and only partly to tenure security. The article develops an ecology of the margins framework and specifies which elements appear transferable and which do not.

1. Introduction

Biodiversity loss is now ranked among the most urgent global environmental problems. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services has documented unprecedented species declines and the systematic erosion of ecological functions across tropical regions [1]. Mutualistic interactions between species, and the regenerative capacity of forest ecosystems, are being lost at rates that exceed species extinction itself [2]. Within this crisis, the role of local communities and grassroots organisations has acquired renewed policy salience. The Kunming-Montreal Global Biodiversity Framework’s 30 × 30 target commits signatory states to protecting 30% of terrestrial and marine areas by 2030 [3]. Community-led mechanisms are central to its delivery. India’s statutory protected-area network—1014 national parks, wildlife sanctuaries, conservation reserves and community reserves—covers about 175,169 km², or roughly 5.32% of the country’s geographical area [4]. Given the present extent of that network, progress towards the 30 × 30 target is likely to depend substantially on other effective area-based conservation measures and other equitably governed landscapes, including areas occupied or managed by local communities.

Northeast India occupies a position of exceptional importance in global biodiversity conservation. It lies at the convergence of two of the world’s 36 biodiversity hotspots—regions holding outstanding concentrations of endemic species under severe threat of habitat loss—namely the Indo-Burma and Eastern Himalaya hotspots [5,6] (Figure 1). It contains roughly 8000 of India’s 15,000 flowering plant species and 14 primate species, including the only ape native to the country [5,7]. Despite covering only 8% of India’s land area, the region accounts for nearly 25% of national forest cover [3]. The Indo-Burma hotspot supports 29 endemic primate species, more than one-fifth of which are globally threatened [7].

The biological wealth is under sustained pressure. Tea plantation, coal mining, hydropower, oil exploration, and rapid infrastructural expansion have all fragmented forest landscapes [8]; remote-sensing assessment of South Asian forest cover since the 1930s documents the resulting deforestation and fragmentation at regional scale [9]. The 2020 controversy over coal-mining approvals inside the Dihing Patkai rainforest illustrates how persistent these pressures remain [8]. Climate models project significant range contraction for endemic Indo-Burma flora by 2050, even under moderate emissions scenarios [10]. Layered upon ecological pressure is a political economy shaped by ethnic conflict, militarisation, and the developmental marginalisation of indigenous communities. These conditions can weaken or complicate conventional state-led conservation [11].

1.1. Research Gap

Within this terrain, indigenous and grassroots organisations have emerged as critical conservation actors. Community Reserves in Meghalaya, Arunachal Pradesh’s Singchung Bugun Village Community Reserve, and Nagaland’s Khonoma and Sendenyu sanctuaries are the regional examples most often cited. The peer-reviewed evidence base, however, is thinnest exactly here: a systematic camera-trap assessment is available for the Community Reserves of Ri Bhoi district, Meghalaya, where mammalian diversity in community-managed lands compares favourably with that of formally protected areas despite the reserves’ smaller size [12], but little comparable published work exists for the others. Detailed academic analysis of long-running Northeast Indian conservation organisations remains rarer still. Most relevant documentation is in vernacular languages. The institutional invisibility of Northeast Indian environmentalism within metropolitan policy discourse has compounded the gap.

The gap this article addresses operates at three levels. At the empirical level, the 4-decade conservation history of Nature’s Beckon has not been systematically analysed: existing publications either focus narrowly on Datta’s literary output [13] or treat individual campaigns in isolation [8,14]. At the analytical level, no account compares the organisation’s different modes of intervention—species-led mobilisation, landscape-scale opposition to extraction, species research and public education, and village-level institution-building—against one another, so it is not known which features recur across them and which belong only to a particular campaign. At the comparative policy level, the organisation’s experience has not been assessed against international findings on community-based conservation success, political opportunity, and institutional durability; comparative meta-analyses of community-based conservation have paid disproportionately limited attention to South Asian frontier conservation [15]. Within Assamese scholarship, meanwhile, Datta’s writing has been read mainly as literature through ecocritical and biographical criticism, rather than as a record of institutional conservation whose results can be assessed [16,17].

Why this particular case should interest readers outside the region can be stated precisely because the question of what makes environmental movements succeed or fail has been examined systematically elsewhere. Scheidel and colleagues’ analysis of 2743 environmental conflicts recorded in the global Environmental Justice Atlas found that mobilisation contributed to halting a destructive project in about 11% of cases worldwide, and that the rate rose to roughly 27% where communities mobilised before a project was established, diversified their forms of protest, and used the courts [18]. Brooks and colleagues’ meta-analysis of community-based conservation projects identified four design features—tenure security, capacity-building investment, equitable benefit-sharing, and effective external linkage to scientific and policy networks—that predicted positive outcomes across national contexts [15]. Studies of land cover reach a parallel conclusion: across the tropics, community-managed forests have sustained annual deforestation rates lower and less variable than those of strictly protected forests [19], and protected areas that treat local people as stakeholders rather than as obstacles are markedly more likely to achieve biological and livelihood gains together [20,21]. Northeast India is largely absent from these datasets. The Nature’s Beckon trajectory is therefore not only a regional history. It is a long-running case supported by official records, peer-reviewed ecological studies, independent reporting, and an extensive first-party institutional archive, with substantial though uneven independent corroboration. That makes it useful for examining how far propositions generated in Latin America, Africa, and Southeast Asia apply in a South Asian frontier setting, and Section 4 uses it for that purpose.

From these three levels, one question follows, and it governs the case studies, the comparative discussion, the policy implications, and the conclusion. This article asks how a long-running grassroots organisation in a politically and ecologically marginal region combined community mobilisation, vernacular knowledge, scientific evidence, and engagement with public institutions in pursuing conservation outcomes, and which features of that process may be relevant beyond Northeast India.

1.2. Research Objectives

Four research objectives follow from this question:

• To document the institutional history and conservation practice of Nature’s Beckon across 4 decades of work;
• To evaluate the conservation outcomes of the organisation’s principal campaigns through a synthesis of organisational records and peer-reviewed scientific data on protected-area effectiveness;
• To derive policy-relevant lessons for community-based conservation in postcolonial frontier regions;
• To situate the case within the international literature on community-based conservation, and to specify which elements of the model appear transferable to other regions and which do not.

1.3. Conceptual Framework: An Ecology of the Margins

The article develops a conceptual framework that we term the ecology of the margins. It designates conservation practice characterised by seven features: operation in geographically peripheral but ecologically significant regions; reliance on vernacular knowledge and vernacular communication; leadership from communities outside metropolitan conservation institutions; integration of scientific evidence with local political mobilisation; resistance to both exclusionary wilderness conservation and extractive development; institutional presence sustained across decades; and negotiation among local communities, state agencies, courts, and public-sector industry. Stated without the terminology: it is conservation built at the edges by the people who live there, out of what they already know, over time spans measured in decades rather than in project cycles. Its orientation is relational—ecological protection is sustained through, not against, the livelihoods of forest-fringe communities. We argue that the practice of Nature’s Beckon offers a developed instance of it. Section 4.4 elaborates the framework, and Section 4.8 states its limits.

The term needs placing against neighbouring vocabularies, and against earlier uses of a similar phrase. Sharma and Pal write of an “ecology at the margins” in Indian comics, reading the environmental and epistemic injustice carried by communities at the edge [22]. The phrase appears earlier still, in a different sense, in social-work writing [23]. We do not claim the words are new. What we offer is a situated analytical framework developed from this case material, and it is worth saying what it is not. It is not simply community-based conservation, which describes who manages a resource but not the knowledge system or the political position from which they do so. It differs in emphasis from political ecology: political ecology analyses power, access, conflict, and the distribution of environmental costs and benefits, whereas this framework foregrounds a recurring institutional mode of conservation practice at geographic, political, and linguistic margins. It is not postcolonial ecocriticism, which reads texts. Here, texts are one instrument among several, and the object of analysis is an organisation. It is not indigenous conservation, since the communities involved include, but are not limited to, Scheduled Tribes, and the institutions concerned are in part newly built rather than customary. It overlaps with environmental justice in its concern for distribution, participation, and recognition, but it focuses more narrowly on how durable conservation practice is organised at developmental and linguistic peripheries. The margins in question are at once geographic, on the frontier where two hotspots meet; political, in a region at the edge of national policy-making; and linguistic, since the working knowledge is held in Assamese.

Nature’s Beckon, an independent environmental organisation registered under the Societies Registration Act in 1991 and founded as a nature club in 1982, occupies a distinctive position within the regional conservation landscape. Based in Dhubri, Assam, the organisation is credited with documenting, in the early 1980s, a previously unrecorded habitat of the golden langur (Trachypithecus geei) in the Chakrashila hill reserve, the movement of more than a decade that culminated in the gazettement of the Chakrashila Wildlife Sanctuary in 1994, the identification in 1992 of what the organisation described as one of India’s largest contiguous tracts of tropical lowland rainforest, and a sustained campaign that contributed to the declaration of the Dihing Patkai Wildlife Sanctuary in 2004 and its upgradation to National Park status in 2021 [24,25]. Its founder, Soumyadeep Datta—whose name also appears transliterated as Dutta in some sources, both forms being in current use—is an Ashoka Fellow and a recipient of the Assam Baibhav civilian honour and has produced more than forty volumes of Assamese-language nature writing. His work combines scientific documentation, ecological commentary, and policy advocacy [13].

2. Materials and Methods

2.1. Research Design

This study is a qualitative comparative case-study synthesis. Four campaigns are reconstructed from documentary, literary, governmental, media, and peer-reviewed scientific sources and are then compared with one another and with the international literature on community-based conservation. The design follows established conventions for qualitative case-study research in conservation social science [12,26] and suits an object of analysis—a long-running, vernacularly documented conservation organisation—whose practice cannot be captured by quantitative ecological survey methods alone. One of the source types is literary, and reading it requires a corresponding method: by ecocritical, we mean the study of how writing relates to the physical environment [27,28] in Glotfelty’s phrase criticism that reads with the earth in mind [29]. Assamese has its own such tradition, and Datta’s books have been read within it as environmental thought [17,30]. That reading is used here as one input among several rather than as the governing approach; the questions this article asks are institutional and policy questions.

Three complementary methods are integrated. The analytical method involves close reading of primary textual sources against established conceptual frameworks. The historical method situates the organisation’s work within the longer trajectory of Indian environmentalism and the colonial-era restructuring of Northeast Indian forest economies. The ecocritical approach reads activist and literary texts as forms of environmental thought in their own right, building on the second-wave ecocritical insistence that environmental ethics, scientific documentation, and political mobilisation are mutually constitutive [27,28].

2.2. Data Sources

Three categories of sources inform the analysis. First, organisational documents include published reports, campaign records, and online archives of Nature’s Beckon, supplemented by news media coverage from regional and national outlets. Second, the literary corpus of Soumyadeep Datta provides primary insight into the organisation’s conservation philosophy. Key works analysed include Aranyar Cha-Pohar, Asomor Abhayaranya Aaru Rashtriya Udyan, Asomor Primate, Namchangor Anteshpur, Asomor Jalasar Charai, and Pratibad Aru Pratyasha. These were chosen because together they cover the parts of Datta’s output that touch conservation: species monographs (Asomor Primate, Asomor Jalasar Charai), studies of protected areas and policy (Asomor Abhayaranya Aaru Rashtriya Udyan, Pratibad Aru Pratyasha), and the narrative of the rainforest movement (Namchangor Anteshpur, Aranyar Cha-Pohar). Each corresponds to one of the campaigns examined below, and the full corpus appears in Appendix A [16,17]. Third, peer-reviewed scientific literature on protected-area outcomes—particularly studies of golden langur populations [31,32], hoolock gibbon habitat fragmentation [33], and Northeast Indian community conservation [9,12]—provides the empirical basis for evaluating ecological outcomes.

The combined source base allows triangulation between organisational self-representation, independent media reporting, and peer-reviewed scientific evidence. The gazette notifications constituting the two protected areas have been obtained and read for this revision, and they are the primary administrative reference points: Notification No. FRW-34/2003/pt/6 of 19 June 2004, declaring the Dihing-Patkai Wildlife Sanctuary [34], and Notification No. FRW.5/2018/386 of 15 June 2021, declaring the Dihing Patkai National Park [35]. Where the notified particulars differ from figures in wide circulation—as they do over the area and date of the national park—we follow the notification and record the divergence. The original 1994 gazette constituting the Chakrashila Wildlife Sanctuary has not been obtained; for that declaration, we rely on the district-administration records of the Government of Assam [36] and state what remains unverified. A note on names is needed. The two areas are notified as the Dihing-Patkai Wildlife Sanctuary and the Dihing Patkai National Park, and the reserved forest at the centre of the dispute is named in both schedules as the Joypur Reserve Forest. The variants Dehing Patkai and Jeypore are in wide use, including in the peer-reviewed literature and in the corporate correspondence discussed below. This article uses the notified forms and retains the variants only inside quoted titles and where a third party’s own usage is being reported. Assamese titles are romanised in the running text according to a single convention; in the bibliography and Appendix A, the spelling printed on each volume is retained, which is why the two do not always coincide.

Something should be said about the standing of these sources and about our own relation to them. Much of the primary record—the organisation’s reports and website, Datta’s books, the commemorative and interview volumes, and a nature-literature number of the Asam Sahitya Sabha Patrika—comes from within the movement, and two of the Assamese volumes were edited or compiled by authors of this article [16,17,37,38,39]. We read it as a vernacular activist archive: reliable for how the organisation understands itself, for its chronology and its ideas, but not as impartial proof that a particular ecological result followed. Claims about outcomes are checked against three independent kinds of evidence—government gazette notifications, peer-reviewed studies, and independent reporting—and where the organisation’s own publications disagree with one another, as they do over species counts and over the exact area and date of the Dihing Patkai declaration, we say so and keep to the verifiable figure. During revision, the organisation communicated a set of corrections to the authors concerning the dating of the Chakrashila discovery, the relation of the Chakrashila campaign to contemporaneous ethnic mobilisation, and the relation of the 2020 digital campaign to its own rainforest movement [40]. That communication is treated here as what it is: a further item of the organisational archive, authoritative for the organisation’s own account and chronology, and checked against independent sources wherever it bears on outcomes or on the actions of third parties. Where it corrects a verifiable matter of fact the text has been amended; where it advances a contested interpretation the text attributes rather than asserts. We set this out plainly so the reader can hold it in view while weighing what follows.

Because the source types differ in what they can establish, the text marks them consistently. Statements resting on the organisation’s own record are attributed to it (“according to Nature’s Beckon’s account…”, “the organisation records…”); statements resting on official notification or administrative record are marked as confirmed (“the notification records…”); statements resting on peer-reviewed work are attributed to the study concerned (“independent evidence indicates…”); statements resting on independent reporting are attributed to the outlet; and our own inferences are presented as interpretation with the evidence on which they rest stated. Where the sources do not support a causal claim we say so, in the form “the available sources do not permit a definitive causal claim”. This matters most for disputed chronology and for attribution of outcomes.

Factual claims were checked by a common protocol. Each date, area figure, and attribution was traced to the most authoritative source obtainable—official notification or administrative record first, then peer-reviewed literature, then contemporaneous independent reporting, then organisational publication—and inconsistent dates and areas were cross-checked across all of them, with the discrepancy recorded in the text rather than resolved silently. The correspondence received from Nature’s Beckon during revision [40] was handled under the same protocol: it is an authoritative institutional clarification but remains a first-party source, and it is not treated as independent proof of any outcome. Where it corrects a matter of fact that can be checked, the text has been amended; where it advances an interpretation our sources cannot settle, the text attributes rather than asserts. Items that could not be resolved are listed as open questions in the Supplementary Materials.

2.3. Analytical Framework

The analytical framework draws on three theoretical resources. Ecocritical theory, particularly the formulations of Buell [27] and Garrard [28], provides tools for reading environmentally oriented texts as ethical and political interventions. Postcolonial environmental thought, articulated by Guha [41] and Huggan and Tiffin [42], frames the analysis of frontier conservation in regions shaped by colonial extraction and ongoing developmental marginalisation. Community-based conservation literature [9,12,43] provides empirical and policy comparators against which Nature’s Beckon’s institutional model is evaluated.

Four case studies were selected on three criteria: (1) documented organisational involvement of Nature’s Beckon; (2) availability of peer-reviewed or government-issued data on outcomes; and (3) representativeness of the organisation’s principal modes of intervention. On the third criterion, the four cases were chosen because they represent distinct intervention types rather than four instances of one thing: species-led protected-area mobilisation (Chakrashila); landscape-scale conservation against extractive pressure (Dihing Patkai); species research combined with public ecological education (primate conservation); and community-managed institutional conservation outside the statutory protected-area categories (the Village Sanctuary). The diversity is deliberate. It is what allows the cross-case comparison in Section 3.7 to distinguish features that recur across intervention types from features specific to a single campaign.

Within each case study, three analytical questions were applied: What was the documented sequence of organisational interventions? What measurable conservation outcomes are associated with those interventions, and what degree of organisational contribution can the available evidence support? And what theoretical and policy-relevant lessons can be derived from the trajectory? Cross-case comparison was used to identify regularities in the organisation’s approach and to distinguish features that appear to be specific to particular campaigns from features that are potentially transferable elements of the institutional model.

2.4. Limitations

Five limitations should be noted. First, the study does not include original ecological survey data; ecological outcomes are evaluated through synthesis of existing peer-reviewed studies. Second, much of the primary documentation is in Assamese; analysis relies on existing English-language scholarship [13] and the organisation’s own English-language publications. Third, the qualitative interpretive approach precludes statistical generalisation. The findings are intended to inform conceptual and policy understanding rather than to support causal inference. Fourth, because much of the documentary record is produced by the organisation under study, attributions of outcome carry the risk of self-representation and are advanced here only where independent notifications, peer-reviewed studies, or media reporting converge with the organisational account; internal inconsistencies in the vernacular sources—differing species counts and declaration figures—further caution against treating any single reported number as settled. Fifth, and by design rather than omission, the study is documentary: interviews with the organisation’s officers were not conducted, both because a 4-decade campaign record is best reconstructed from contemporaneous texts and because our analytical interest is in the public and institutional forms the movement’s knowledge has taken. An interview-based ethnography of the eco-emissary network would be a valuable complement and is proposed in Section 5.

2.5. Use of Generative AI

Generative AI-assisted tools were used during revision to assist with language refinement, structural organisation, and the drafting of selected explanatory and response-letter passages. All factual claims, references, interpretations, source selections, and final wording were independently checked, revised, and approved by the authors, who take full responsibility for the manuscript.

3. Nature’s Beckon in Practice: Institutional History and Campaign Analyses

3.1. Nature’s Beckon: Genesis, Mission, and Institutional Praxis

Nature’s Beckon was founded in 1982 as a small nature club in Dhubri, the principal town of the lower Brahmaputra valley in western Assam. Its early activities consisted of bird-watching expeditions and forest trails in the Dhubri reserves [24]. Formal registration under the Societies Registration Act came in 1991. Registration enabled the organisation to publish books and research papers, engage in formal advocacy with the Forest Department of Assam, and access modest project funding. It also brought the organisation within the ordinary field of pressures that funding relationships and official standing create. Nature’s Beckon states that it refuses sponsorship from extractive industries operating in its working areas, and no contrary evidence was identified in the sources examined for this study. However, no organisation is immune to the expectations of its donors and official interlocutors, and we make no claim that Nature’s Beckon has been exempt from them.

The founding moment coincided with a critical phase of regional political history. The Assam Movement of 1979–1985 had produced a regional public sphere unusually attentive to questions of land, demography, and resource sovereignty, and the Bodoland autonomy agitation launched in 1986–1987 would shortly make the question of who holds forest land sharper still. Nature’s Beckon’s first major campaign was at Chakrashila, a hill tract then administered through the Dhubri forest division of the state forest department; parts of what became the sanctuary were incorporated into the Bodoland Territorial Region only in 2003, and the sanctuary today straddles the Dhubri and Kokrajhar districts. The sequence matters for how the campaign’s success should be explained. The organisation records that the movement began in the early 1980s from a Rabha fringe village that remained its nerve centre throughout, and that it had built a grassroots base among forest-fringe communities before the Bodoland agitation began. On its own account, its legitimacy derived not from ethnic-autonomy politics but from a conservation mission framed in pan-Indian terms, as the organisation’s mission statement makes explicit [24,40]. We record that account rather than treating the campaign as a by-product of contemporaneous ethnic mobilisation. What can be said with more confidence is narrower: the campaign worked in a landscape where customary claims to forest land by the Rabha and the Bodo were live and contested, and its insistence that forest-fringe communities were custodians rather than encroachers was legible in that setting [11]. The early embedding of conservation work in a periphery where questions of land and belonging were unsettled gave the organisation a distinctive starting point. It also exemplifies the ecology of the margins in formation: an environmentalism that draws its legitimacy from peripheral political traditions rather than from metropolitan environmental discourse.

Three commitments distinguish Nature’s Beckon’s organisational philosophy. First, people’s participation is treated as the foundation of conservation rather than as a residual concession to social acceptability. Forest-fringe villages are framed as long-term custodians of the ecosystems in question, rather than as obstacles or passive beneficiaries [24]. Second, scientific documentation is integrated with advocacy. Each major campaign has been accompanied by baseline biological surveys, species checklists, and published monographs that establish the empirical basis for protected-area declaration. Third, the organisation operates an eco-emissary model: youth from forest-fringe villages are trained in conflict resolution, biodiversity assessment, lobbying, photography, and rescue work. According to the Ashoka Foundation’s published profile of Soumyadeep Datta, training has been conducted across more than 60 allied organisations, and over 3000 trained volunteers have been associated with the network across 4 decades [44].

The geographical scale of activity extends across all of Assam, with operational reach into Arunachal Pradesh and Meghalaya. Of Assam’s 328 reserved forests, the organisation has prioritised 12 on the basis of fragile ecosystems, endangered wildlife, and severity of encroachment [44]. Baseline surveys have been conducted at Chakrashila, Manas National Park, Dibru-Saikhowa National Park, Panidihing Wildlife Sanctuary, Garampani Wildlife Sanctuary, and Dihing Patkai Wildlife Sanctuary [24].

A distinguishing feature of the organisation’s stated politics is its refusal of corporate sponsorship from extractive industries that operate in its working areas. At the same time, its approach has not been doctrinaire. During the Joypur (also written Jeypore) campaign, the organisation entered formal dialogue with senior officials of Oil India Ltd. (Duliajan, Assam, India) and Coal India Ltd. (Kolkata, West Bengal, India) to negotiate the release of the Joypur Reserve Forest from existing lease agreements [25]. This combination of principled opposition and tactical engagement reflects an institutional politics calibrated to the specific conditions of Northeast Indian conservation, where forest administration is often under-resourced and extractive capital well-organised.

The organisation’s publishing programme provides an additional element of institutional infrastructure. Nature’s Beckon has produced a series of conservation-focused volumes, including Chakrashila Wildlife Sanctuary, Asomor Abhayaranya Aaru Rashtriya Udyan, and Asomor Primate, alongside numerous popular articles in regional and national outlets [13,24]. The publishing function is operationally significant for three reasons. It builds the documentary archive on which protected-area declarations have been argued for and won. It cultivates a vernacular conservation public that can be mobilised at moments of crisis, as occurred in 2020, when the organisation ran its own campaign for the full 500 km²—#CompleteDihingPatkaiWLS_500sqkm—through the COVID-19 restrictions and drew wide support within Assam [40]. Section 3.4 distinguishes that campaign from the separate and better-known digital protest over the Saleki colliery. The episode carries a lesson beyond Assam: the readership that made rapid mobilisation possible had been assembled slowly, in Assamese, across the preceding 3 decades. Speed of mobilisation is often treated as a property of digital media. Here, it was the return on a long prior investment in a vernacular public. Third, the publishing programme provides a continuing source of intellectual capital that can be drawn upon by allied organisations, including state forest departments and academic institutions, for whom the organisation’s output has become a primary reference resource.

3.2. Soumyadeep Datta as Conservationist-Intellectual

Any analysis of Nature’s Beckon must engage with its founder-director, Soumyadeep Datta, while keeping the two distinct. What follows concerns his personal writing and intellectual contribution; the institutional record of the organisation, the part played by forest-fringe communities, the actions of government, and the work of allied activists and researchers are treated separately in Section 3.1, Section 3.3, Section 3.4, Section 3.5, Section 3.6 and Section 3.7. Born and raised in Dhubri, Datta’s early years were shaped by the avifauna of the lower Brahmaputra and by an emerging consciousness of ecological crisis [13]. The Ashoka Foundation’s selection of Datta as a Fellow in 1998 framed his contribution in terms of “organising indigenous youth groups to conduct conflict resolution and environmental preservation in the strife-torn northeastern region of India” [44]. In 2024, Datta received the Assam Baibhav, the highest civilian honour of the state government, recognising decades of conservation work that had often involved direct opposition to government policies [24].

Datta’s literary corpus comprises more than 40 volumes of Assamese-language nature writing. The works range from species monographs (Asomor Jalasar Charai, Asomor Chikari Charai, Asomor Primate) to landscape studies (Aranyar Cha-Pohar, Namchangor Anteshpur) and policy-oriented texts (Asomor Abhayaranya Aaru Rashtriya Udyan, Pratibad Aru Pratyasha) [13]. The corpus is distinctive for refusing several conventions of Anglophone nature writing. Western nature writing has often relied on a solitary observer encountering an unpeopled wilderness [27]. Datta’s writings are different. They are densely populated. Forest-fringe villagers, indigenous hunters, forest officials, students, journalists, and oil-company managers all appear as interlocutors. The forest is not a pristine elsewhere. It is a contested, multi-tenanted space whose ecological future depends on the social relationships traversing it. The corpus is, in this sense, a written expression of the organisation’s conservation philosophy.

Datta’s writing functions not as commentary on activism but as a constituent part of it. Each major Nature’s Beckon campaign has been accompanied by clusters of texts—species monographs, popular essays, full-length books, contemporary blog posts—that constitute the documentary infrastructure on which protected-area declarations have been argued. Three consequences follow. The texts produce a vernacular public sphere in which conservation is debated in Assamese and accessible to non-Anglophone readers. They preserve campaign history in formats that often constitute the principal archival record. They position Datta and Nature’s Beckon as historians of the movement, ensuring that the meaning of campaigns is contested by participants rather than retroactively settled by external analysts.

Recent interventions during the 2020 COVID-19 pandemic and the simultaneous Dihing Patkai mining crisis indicate the continuing relevance of Datta’s public role. In a widely circulated video essay, Datta linked the pandemic to the long history of human encroachment on forest ecosystems. He argued that pandemic disease is a structural product of the modernity that destroys habitat boundaries [24]. The argument mirrors the One Health perspective that has since gained traction in international conservation policy [45]. We do not claim priority for Datta: the concept was already taking shape in the international literature. The convergence is significant for a different reason. Vernacular environmental thought, far from being parochial, can arrive independently, and in another language, at framings the international scientific community has reached by its own route. Recognising such convergences is itself a condition for a genuinely globalised conservation discourse.

3.3. Case Study 1: The Chakrashila Wildlife Sanctuary Movement (Early 1980s–1994)

The first major campaign undertaken by Nature’s Beckon was the movement of more than a decade that secured protected status for the Chakrashila hills, a tract then administered through the Dhubri forest division and today falling across the Dhubri and Kokrajhar districts. In the early 1980s, Soumyadeep Datta documented the presence of the golden langur (Trachypithecus geei) in the Chakrashila Reserve Forest, identifying a previously unrecorded habitat of the species in this part of Assam—a locality outside the belt to which it had been thought confined along the Indo-Bhutan border [31]. The campaign followed. The species itself had been described from Goalpara in the 1950s, so the claim is not that Datta discovered it. On that basis, the earlier characterisation of the event in the preprint version of this article as a “rediscovery” was inaccurate and has been withdrawn. Datta published an account of it, and of its conservation implications, in Tiger Paper in 1998 [46], and later peer-reviewed literature independently identifies Datta as the first to report the occurrence of the golden langur at Chakrashila [47]. The organisation further records that the Zoological Survey of India verified the finding after field assessment by its own scientists [40]; we have not seen that document and report the claim as the organisation’s own. The dating is not entirely settled: the organisation places the discovery in the early 1980s, whereas the Ashoka Foundation’s fellowship profile refers to the later part of that decade [44]. We follow the organisation’s dating, which is consistent with its account of a movement of more than 12 years, culminating in 1994, and note the discrepancy. The species had been classified as Endangered on the IUCN Red List, and Chakrashila was established as the only protected habitat for it in India.

The campaign followed a model that subsequent Nature’s Beckon interventions would replicate. Comprehensive forest area surveys produced checklists of birds, mammals, reptiles, plants, and other species. The surveys established that Chakrashila harboured not only the golden langur but also Chinese pangolin (Manis pentadactyla), clouded leopard (Neofelis nebulosa), great hornbill (Buceros bicornis), king cobra (Ophiophagus hannah), and approximately 250 species of birds [48]. On the basis of this documentation, Nature’s Beckon mobilised forest-fringe Bodo and Rabha villages, building public pressure through media advocacy and direct community action, including planting food plants for the langur, creating artificial salt licks, and clearing invasive weeds such as Mikania micrantha [48].

On 14 July 1994, the Government of Assam declared Chakrashila a Wildlife Sanctuary covering 45.568 km² across what are now the Dhubri and Kokrajhar districts, the hill having been constituted a reserved forest in 1966. The declaration is reported as Notification No. FRW-6/93/63 of that date and is recorded by both district administrations [36]. The original gazette has not been obtained by us, and the notification number should be treated as unverified. Demographic data for the sanctuary population exist, although they are not recent. The first systematic survey, carried out between December 2006 and January 2007 using line transects and total counts, recorded 474 golden langurs in 64 troops in and around the sanctuary, with a mean group size of 7.40, an adult sex ratio of 1:1.53, an age structure of 49.8% adults, 33.5% juveniles and 16.7% infants, and an estimated density of 65.83 individuals per km². A further count in 2009 recorded 501 individuals in 66 groups [47]. The authors of that survey read the age structure as indicating a healthy and growing population while cautioning that the unusually high density may reflect an absence of dispersal opportunity following the loss of connectivity with adjacent forest at Nayakgaon and is therefore a medium-term risk as much as a sign of health [47]. Occupancy modelling nearly 2 decades later estimates a probability of golden langur occurrence of 0.69 ± 0.08 SE in the southern fragments that include Chakrashila [32]. Occupancy measures where a species is found, not whether its population can persist; a high occupancy estimate is consistent with viability but does not establish it. Peer-reviewed work has also documented continuing pressure, including 18 langur–vehicle collisions on State Highway 14 between January 2023 and December 2024, resulting in seven deaths, five major injuries, and six minor injuries while confirming the sanctuary’s role as the only consolidated protected habitat for the species in India [49]. What this evidence supports is a substantial and structurally sound population at Chakrashila as of 2006–2009, continued high occupancy in the surrounding fragments as of 2024, and continuing anthropogenic mortality. What it does not support is a claim about population trend or viability: two counts 2 years apart do not establish a trend, and no demographic assessment specific to Chakrashila has been published since 2009. The most recent range-wide assessment estimates a minimum of 7396 golden langurs in India [32], but that is a range-level figure and does not resolve the Chakrashila population. A current demographic assessment of the Chakrashila population remains an outstanding research need.

The Chakrashila campaign also prefigured a wider idea that Nature’s Beckon would take up later: the Village Sanctuary, in which a village looks after a nearby forest itself, accepting limits on commercial use in return for continued subsistence access. Its first formal instance came in another part of the state, at Chalapathar in Charaideo district, and Section 3.6 returns to it [24].

Analytical summary. The marginality at work in this case is geographic and administrative: a reserve forest at the western edge of the state, outside the protected-area network and outside metropolitan conservation attention. The knowledge mobilised was field documentation compiled locally and published in Assamese, later corroborated by peer-reviewed population survey, occupancy, and road-mortality studies [32,47,49]. The community role was central rather than consultative: the campaign was run from a forest-fringe village, and villagers carried out habitat work directly. The scientific evidence used in advocacy was the organisation’s own species checklists. No political opening has been identified for this case; the outcome appears to have followed the accumulation of local pressure over more than 12 years. The result was a Wildlife Sanctuary of 45.568 km², notified on 14 July 1994. What appears transferable is the demonstration that locally held species documentation can convert a reserve forest into a protected area without external funding; what is specific to this case is the presence of a stable village base and a single charismatic and legally protectable species.

3.4. Case Study 2: The Dihing Patkai Movement (1992–2021)

The Dihing Patkai campaign represents the largest-scale and longest-duration intervention undertaken by Nature’s Beckon. The campaign began in 1992, when Datta first identified, named, and documented the existence of a contiguous tropical rainforest in the Dibrugarh and Tinsukia districts of Upper Assam. The presence of these forests had not previously been recorded in official documents or scientific publications [25]. The identification changed the conservation politics of the region: the Dihing Patkai forests came to be described, by the organisation and subsequently in wider commentary, as one of India’s largest contiguous tracts of tropical lowland rainforest.

From 1994, Nature’s Beckon led a movement for legal protection of approximately 500 km² of rainforest spanning the Joypur, Upper Dihing, and Dirok Reserved Forests. The campaign produced an extensive output of monographs and popular writings, including Rainforests of Assam, Namchangor Anteshpur, and Dihing Patkai Abhayaranya [24]. After a decade of advocacy, the Government of Assam declared 11,119.42 hectares—111.19 km²—of rainforest as the Dihing-Patkai Wildlife Sanctuary, by Notification No. FRW-34/2003/pt/6 of 19 June 2004, made under Section 26-A(1)(b) of the Wild Life (Protection) Act 1972 and published in the Assam Gazette Extraordinary of 22 June 2004 [34]. The date is frequently reported as 13 June 2004. The notification itself is dated the 19th. The 2004 declaration fell well short of the 500 km² target. The Joypur Reserve Forest, ecologically integral to the rainforest matrix, was excluded because Coal India Ltd. and Oil India Ltd. held mining and exploration leases over the area. The 1973 lease had formally expired in 2003, but operations had continued in violation of the Forest (Conservation) Act 1980 and the Wildlife (Protection) Act 1972 [8].

The 2020 mining controversy brought the landscape to a national audience, though its relation to the rainforest campaign requires care. In April 2020, during the COVID-19 lockdown, the Standing Committee of the National Board for Wildlife approved the diversion of forest land in the Saleki Proposed Reserve Forest for an open-cast coal project of North Eastern Coalfields. Whether Saleki lies inside the sanctuary was disputed at the time and remains so. Much reporting placed it within Dihing Patkai; forest-department verification presented to the State Board for Wild Life placed it some 9 kilometres outside the sanctuary, within the eco-sensitive zone and within the Dehing Patkai Elephant Reserve, where mining is not barred by the Wildlife (Protection) Act [50]. Nature’s Beckon took the latter position publicly in 2020 and maintains it [40]. On that account, the site lay outside both the 111.19 km² sanctuary and the 500 km² the organisation had proposed for protection.

The approval generated a large digital campaign under the hashtag #SaveDehingPatkai, joined by activists, students, conservation organisations, and cultural figures, and followed by public interest litigation challenging the legality of the mining [8]. Nature’s Beckon publicly distinguished its own campaign from this broader mobilisation and regarded the two as having different objectives: the #SaveDehingPatkai campaign was directed at the Saleki colliery rather than at the legal status of the rainforest and drew on a constituency the organisation had not mobilised [40]. Over the same months, the organisation ran its own campaign, #CompleteDihingPatkaiWLS_500sqkm, pressing its long-standing demand for the full 500 km², and records wide support for it within Assam [40]. We record the distinction because it bears directly on attribution: the published academic account has tended to treat the 2020 mobilisation as a single phenomenon and to read the park declaration as its outcome [8]. The individuals named in that account as prominent supporters of the digital campaign are not, on the organisation’s record, participants in its rainforest movement [40], and this article makes no claim that they were.

How the Joypur question was settled is documented, but not by material we have been able to inspect. Nature’s Beckon’s published account and its 2026 communication to the authors report that in September 2020, the two public-sector companies holding claims over the disputed forest wrote to the organisation [40,51]. The two commitments were distinct and should not be merged. North Eastern Coalfields, a unit of Coal India, is reported to have agreed to surrender its colliery leases in the Joypur Reserve Forest so that the area could be added to the proposed park. Oil India is reported to have undertaken not to drill in what its letter names the Jeypore Reserved Forest—the Joypur Reserve Forest of the gazette schedules—describing it as a biodiversity hotspot. An undertaking not to drill is not the same legal act as the surrender of a lease. The original corporate correspondence was not available to the authors for inspection, and its content is reported here as the organisation reports it. Nature’s Beckon states that the reported undertakings followed direct discussions with the organisation and were not mediated by the National Green Tribunal [40]. That account does not exclude the broader legal, administrative, electoral, and public pressures surrounding the controversy. What the reported undertakings would have removed are the encumbrances that had kept the reserve outside the 2004 sanctuary. What followed in the notified boundary is a separate question. The 2021 schedule describes a park boundary running along the northern boundary of the Joypur Reserve Forest and admits rights of passage on roads leading from Joypur through the park [35]. We have not worked the coordinate schedule, and we do not infer the extent of the enlargement from the correspondence. Section 4.5 develops the point.

The declaration was made in two steps. The Government of Assam approved the upgradation of the sanctuary to national park status in December 2020, and the constituting notification followed: No. FRW.5/2018/386, dated 15 June 2021, made under Section 35 of the Wild Life (Protection) Act 1972 and published in the Assam Gazette Extraordinary of 16 June 2021, declaring the Dihing Patkai National Park across the Tinsukia and Dibrugarh districts and the Digboi and Dibrugarh forest divisions [35]. Two particulars of the notification differ from the figures in general circulation, and because the notification is the legally operative document, we follow it. The notified area is 234.26 km², not the 231.65 km² reported by the Tinsukia district administration [52], by the peer-reviewed account of the episode [8] and by the organisation’s own publications [51]; the Dibrugarh district record gives the notified figure [53]. And the notification is dated 15 June 2021, and published on 16 June, not 7 or 9 June, as variously reported. We record the divergence rather than resolving it silently and note that the difference of 2.61 km² does not bear on any argument made here. On either figure, the park more than doubles the area protected under the 111.19 km² sanctuary of 2004. The organisation’s own account gives the same two-step sequence—an initial notification in 2020 and the final gazette notification in 2021 [40]. The trajectory from the 1992 identification to the 2021 notification represents a near-3-decade arc of sustained movement-building. As Sengupta and Borgohain note in their analysis of the 2020 mobilisation, the protests reflected a productive contradiction between metropolitan and indigenous versions of ecological nationalism [8]. The metropolitan version was articulated through Anglophone social media and celebrity endorsements. The indigenous version was rooted in long-term grassroots organising by communities mobilised by Nature’s Beckon and allied groups. Both registers contributed to the success; the indigenous version, however, had established the conditions of possibility for the metropolitan moment.

The ecological significance of the Dihing Patkai protection extends beyond the headline area. The forest hosts more than 290 bird species, 47 mammal species, and serves as a critical habitat for the western hoolock gibbon, the endangered Asian elephant (Elephas maximus), and several globally threatened reptiles [14]. Recent satellite-based assessments have nonetheless documented continuing pressure: rat-hole mining operations have persisted in adjacent reserve forests, and satellite imagery from January 2025 revealed extensive denudation within the park’s boundaries, with mining activities encroaching on protected zones [8,14]. The trajectory thus illustrates both the achievements of sustained grassroots advocacy and the structural limits of formal protection in the absence of effective enforcement.

Analytical summary. The marginality here is economic and jurisdictional: a rainforest overlain by petroleum and coal interests in a district where extraction long preceded conservation administration. The knowledge mobilised was the organisation’s own identification and survey of a rainforest not previously recorded in official documents, published in Assamese across 3 decades. The community role was to sustain a constituency across three reserved forests over that period and to supply the readership that could be mobilised at short notice in 2020. The institutional opening was decisive and is the reason this case matters for the article’s wider argument: the movement had existed for decades, and that long advocacy created institutional memory, community legitimacy, documentation, and the standing to negotiate, but the protected-area outcome became possible only when that accumulated capacity intersected with a favourable political and administrative opening. Campaign duration alone did not guarantee success; success depended on timing, state support, reported direct discussion with the leaseholders, and administrative action. The result was a national park of 234.26 km², as notified. What appears transferable is that accumulated standing can secure by negotiation what is elsewhere pursued through litigation; what is specific is the presence of public-sector rather than private leaseholders, which made negotiated relinquishment institutionally possible at all.

3.5. Case Study 3: Primate Conservation

The third dimension of Nature’s Beckon’s contribution concerns primate conservation, particularly its sustained engagement with the western hoolock gibbon (Hoolock hoolock) and the golden langur. Hoolock gibbons—the only ape native to India—are classified as Endangered on the IUCN Red List. Peer-reviewed work documents that habitat fragmentation by tea gardens, roads, oil exploration, and the railway line that bisects the Hollongapar Gibbon Sanctuary in Assam has produced a slow attrition of local primate populations [33]. Reporting from 2025 places the surviving Hollongapar population at approximately 125 individuals [54]. The Lumding-Dibrugarh railway electrification, confirmed in 2024, has further alarmed conservationists [54].

Three kinds of contribution should be separated because they are not equivalent. The first is species documentation: baseline surveys at Dihing Patkai and elsewhere, and the publication of Asomor Primate and other species monographs. The second is public awareness and vernacular publication: popular articles, school materials, and nature trails that carried primate conservation into Assamese public discussion. The third is measurable ecological outcome, and here the evidence is weaker. Documentation and awareness are inputs; population recovery is an outcome, and no study known to us attributes a change in primate abundance to the organisation’s work. What can be documented is that its surveys and monographs supplied part of the evidential basis for protected-area advocacy at Dihing Patkai, and that its use of the golden langur and the hoolock gibbon to argue for whole ecosystems rather than for single species corresponds to the “umbrella species” reasoning of conservation biology [55]. Partnerships with research-driven organisations such as Aaranyak supplied external scientific linkage.

A particularly notable development is the emergence of community-led co-existence models in proximity to areas where Nature’s Beckon has long worked. At Barekuri village near Tinsukia, residents protect trees around their homes so that gibbons can move freely [56]. Recent ecological work confirms the conservation value of this kind of community-based approach: occupancy modelling for golden langur shows that probability of presence is positively associated with intact forest cover and inversely associated with anthropogenic edge effects, both of which can be more effectively managed at the community than at the protected-area scale [32]. The translocation programme to establish a second golden langur population at the Manas-Umananda island, although outside Nature’s Beckon’s direct operational area, builds on the species-conservation infrastructure that the organisation’s earlier work helped to establish.

Habitat fragmentation analysis underscores the urgency of these efforts. Sharma and colleagues’ work on Upper Brahmaputra Valley primate communities documents that local primate distribution is most strongly associated with intact forest cover, the presence of large fig trees, and proximity to undisturbed core forest [33]. The same study identifies edge effects from tea plantations and roads as primary determinants of primate occupancy decline. The findings provide empirical support for the kind of landscape-scale, connectivity-focused conservation approach that Nature’s Beckon has consistently advocated, and they indicate that the organisation’s emphasis on contiguous rainforest protection at Dihing Patkai has been ecologically prescient.

The terms used in this section are not interchangeable and are used strictly. Presence is a record at a site; occupancy is the modelled probability of presence across sites; density and abundance are numbers per unit area and in total; population trend is change in abundance over time; and viability is the probability of persistence. For the golden langur at Chakrashila, presence, occupancy, abundance, density, and age structure are all documented, but at widely separated dates: abundance, density, and age structure from the counts of 2006–2007 and 2009 [47], occupancy from modelling published in 2024 [32]. Population trends and viability are not documented, and no claim about either is made here; two counts 2 years apart do not establish a trend. For the western hoolock gibbon at Hollongapar, an abundance figure has been reported [54], but that site lies outside the organisation’s operational area, and the figure is not attributed to its work.

Analytical summary. The marginality in this case is epistemic: species of high international conservation concern whose local documentation existed largely in a language international science does not read. The knowledge mobilised was field observation converted into Assamese species monographs. The community role was co-existence practice at forest-fringe villages and the training of eco-emissaries drawn from them. The scientific evidence is partly the organisation’s own and partly independent [32,33]. No political opening applies because there was no single decision point. The outcome is documentation and public education rather than measured ecological change, and this is the case in which the limits of the organisation’s evidence are clearest. What is transferable is the practice of arguing from charismatic species to whole ecosystems; what is not is the existence of a reading public in the relevant vernacular.

3.6. Case Study 4: The Village Sanctuary Model and Eco-Education

The Village Sanctuary is the organisation’s most original institutional contribution. It is a community-run arrangement that sits outside the statutory categories of Wildlife Sanctuary and Community Reserve: a village takes on the protection of a forest and accepts limits on its commercial use while keeping access for its own needs. The clearest case is the Chala Village Sanctuary at Chalapathar in Charaideo district, in eastern Assam, where the Tai Khamyang Buddhist community has taken charge of the adjoining Chala Reserve Forest; the organisation records it as the first Village Sanctuary in the state, and the arrangement has since been taken up at other forest-fringe sites [24]. The organisation’s account places its establishment in the 2010s; the precise year remains to be confirmed from the registration or foundation records of the Chala Village Sanctuary Conservation Society, and we give a decade rather than a year for that reason.

The Village Sanctuary model resonates with the established literature on common-pool resource governance, which has demonstrated that under appropriate institutional conditions, communities can sustainably manage shared resources without privatisation or state command [57]. The comparative evidence for that proposition is now substantial and international. Porter-Bolland and colleagues’ meta-analysis of 40 protected areas and 33 community-managed forests across the tropics—drawing heavily on Mexico, Guatemala, and the Brazilian Amazon—found that community-managed forests sustained annual deforestation rates both lower and less variable than those of strictly protected forests [19]. A global meta-analysis of 165 protected areas reached a complementary conclusion: protected areas that gave local people a genuine stake, and that supported cultural and livelihood values, were substantially more likely to deliver conservation and socioeconomic gains together than those managed by exclusion [20]. A systematic review of 169 studies of conservation governance found that positive outcomes for both wellbeing and biodiversity came overwhelmingly from cases in which Indigenous peoples and local communities held substantial decision-making power and in which customary tenure institutions were recognised within the governance arrangement [21]. Nearer at hand, Lyngdoh and colleagues’ camera-trap assessment of five Community Reserves in Ri Bhoi district, Meghalaya, recorded 23 mammal species across the five reserves [12].

Compared on institutional rather than superficial criteria—local rule-making, community monitoring, customary authority, tenure, livelihood integration, external scientific support, legal recognition, and durability—the Village Sanctuary resembles the international cases in most respects and differs sharply in two. Local rule-making, community monitoring, livelihood integration, and external scientific support are present at Chala much as they are in Mexican community forests or Nepalese forest user groups. Tenure and legal recognition are not: the arrangement occupies no statutory category and rests on no secure right. Durability is therefore the open question, since in the comparator systems, legal recognition preceded the conservation outcomes and is generally credited with sustaining them.

What the Nature’s Beckon case adds to this literature is a point about origins rather than outcomes. In most documented Latin American and South Asian cases, community management builds on tenure or custom that already exists: Mexican ejidos, Amazonian indigenous territories, the customary forest institutions of Meghalaya and Nagaland. Chala did not begin with an intact institution of that kind; the arrangement was constructed over years with a community whose prior relation to the adjoining forest had been disrupted. Four further features distinguish the organisation’s model from the comparators: vernacular publication used as conservation infrastructure rather than as outreach; a structured eco-emissary training programme; an organisational presence sustained across decades rather than project cycles; and direct negotiation with both state agencies and public-sector industry. If the origins point holds elsewhere—and a single case cannot establish that—then the design features the comparative literature identifies as predictors of success need not be inherited. They can be built, which matters more for the many landscapes in which such traditions have broken down than for the few in which they survive intact.

Educational work complements institutional building. The organisation has run children’s nature trails, mobile exhibitions, and eco-tourism workshops; trained conservation volunteers across more than 60 allied organisations; and produced popular materials in Assamese for school audiences [24,44]. Datta’s articulated stance on eco-tourism—distinguishing ecological education and modest local livelihood from commodified spectacle—is a substantive intervention in a region where mass tourism oriented to Kaziranga and Manas has often produced new pressures on protected ecosystems [13]. The educational programme has cultivated a regional cadre of ecologically literate citizens whose presence is a precondition for any sustained environmental politics in the longer term.

The Village Sanctuary model has implications for the recently emerging policy framework around Other Effective Area-Based Conservation Measures (OECMs), which the Government of India has identified as a key vehicle for meeting its 30 × 30 commitments under the Kunming-Montreal Global Biodiversity Framework [3]. Village Sanctuaries developed by Nature’s Beckon and similar arrangements would naturally fit within this OECM framework, and their formal designation could substantially expand the proportion of national territory under effective biodiversity conservation without requiring new protected area gazettements.

Analytical summary. The marginality here is legal: a community-managed forest that fits none of the categories of the Wildlife (Protection) Act. The knowledge mobilised was the community’s own and the organisation’s institution-building experience. The community role is constitutive rather than participatory: the Tai Khamyang community is the managing institution. Independent scientific evidence for ecological effect is absent, and we say so. No political opening applies because the arrangement does not depend on a governmental decision; that is simultaneously its strength and its vulnerability. The outcome is a functioning institution of uncertain durability. What is transferable is the method of building a community institution where custom has broken down; what is not is the particular cohesion of the community concerned. The case also identifies the policy lever most likely to matter: recognition as an Other Effective Area-Based Conservation Measure would supply the legal standing the arrangement lacks.

3.7. Cross-Case Synthesis

Across the four case studies, four recurrent operational patterns emerge. First, every successful campaign was preceded by sustained baseline biological survey work that established the species and habitat values at risk. Second, advocacy work integrated formal engagement with state institutions (the Forest Department, the Ministry of Environment) with mobilisation of local communities and—where feasible—national media. That combination is less straightforward than it sounds in a region where relations between the state and forest-dwelling communities have often been adversarial, and three features appear to have made it workable. The organisation entered official discussions carrying its own survey data and documentary record, which strengthened its position as a technical interlocutor rather than only as a claimant. It kept its community work and its official work in separate registers—the first in Assamese and in the villages, the second in English and in Dispur and Delhi—so that neither compromised the other. And it distinguished consistently between the forest bureaucracy, with which it cooperated, and the extractive interests operating under state licence, which it opposed; that distinction made cooperation possible without endorsement. Third, the organisation’s documentary output served as the principal reference resource for academic, policy, and media engagement with the relevant landscapes. Fourth, institutional outcomes were achieved over time horizons of 1–3 decades, each campaign building on the documentary infrastructure and political capital generated by earlier interventions.

This pattern indicates that the organisation’s conservation record cannot be attributed to any single intervention or to charismatic leadership alone. It is associated with a structured institutional practice combining knowledge production, community engagement, and political advocacy across long time horizons. The four operational patterns above can be read as the working signature of the ecology of the margins: knowledge drawn from more than one tradition, both vernacular and scientific; institutions that link communities, state, and NGO rather than setting them against one another; and patience measured in decades. Because these are properties of an organisational model rather than of one person or one place, they are in principle portable.

sets the four cases side by side on the dimensions that matter for that judgement, and Section 4.4, Section 4.5, Section 4.6 and Section 4.7 examine it.

4. Analysis: Outcomes, Framework, and Comparative Position

4.1. Long-Term Organisational Capacity

The combined evidence from the four case studies indicates that Nature’s Beckon has produced measurable, durable conservation outcomes. Two protected areas—the Chakrashila Wildlife Sanctuary, 45.568 km², and the Dihing Patkai National Park, 234.26 km², a combined notified area of approximately 279.83 km²—were constituted following campaigns in which Nature’s Beckon played a documented and substantial role [24,25]. The Chakrashila Wildlife Sanctuary remains the only consolidated protected habitat for the golden langur in India, and recent occupancy modelling confirms that the species continues to occur at relatively high probability across the southern fragments that include the sanctuary [32]. The Dihing Patkai National Park has secured legal protection for a large contiguous tract of tropical lowland rainforest in eastern Assam, although mining pressures on adjacent reserve forests persist [8]. The terms of attribution are best stated here rather than qualified later. Gazettement is an act of the state, and in both cases, it occurred when a political opening allowed it. What the evidence supports is that Nature’s Beckon built the ecological case, the documentary record, and the public constituency without which neither declaration would have been available to be made when the opening arrived; Section 4.5 sets out the qualification in full, and Section 4.8 the limits of the evidence.

These outcomes are notable in three respects. They have been achieved without large-scale international funding or media attention; they have proceeded through cumulative advocacy over multi-decadal time horizons rather than through single-event mobilisations; and they have been built through partnership with communities whose involvement has been substantive rather than tokenistic. Each of these features distinguishes Nature’s Beckon from many contemporary conservation organisations and offers transferable lessons for community-based conservation in other postcolonial contexts.

The temporal dimension warrants particular emphasis. The Chakrashila campaign required 12 years of sustained advocacy before formal gazettement; the Dihing Patkai trajectory unfolded across nearly 3 decades from initial identification (1992) to full national park status (2021). Comparative work on protected-area effectiveness has consistently identified institutional continuity as a critical variable: campaigns led by long-lived organisations produce more durable outcomes than short-cycle projects because the organisation persists across the political openings for which a project cannot wait [15]. Nature’s Beckon’s experience supports this conclusion empirically. It also indicates a structural mismatch. Dominant conservation funding cycles run for 3–5 years. Lasting protected-area declarations, however, take 15–30 years. Funding mechanisms designed around short cycles are ill-suited to support the kind of sustained advocacy the case studies show is necessary.

A second comparative observation concerns the scientific basis of advocacy. The empirical foundation of each major campaign was a baseline biological survey, with checklists of birds, mammals, reptiles, and plants establishing the conservation value of the proposed protected area. This is unremarkable in international conservation practice, but it remains uncommon in vernacular South Asian conservation, where advocacy more often proceeds through general appeals to environmental value than through species-specific documentation. Subsequent peer-reviewed studies have largely been consistent with the species and habitat assessments the organisation developed in the 1980s and 1990s [31,32,49], which suggests that the empirical work was sound rather than merely rhetorical. Taken together with the design-feature comparison set out in Section 4.6, this is the clearest evidence that the organisation’s capacity, and not any single campaign, is what produced its record.

4.2. Vernacular Knowledge as Institutional Infrastructure

The most distinctive element of the model is the use of vernacular publication as infrastructure rather than as outreach. Across the four cases, Assamese-language publication performed three functions that in other conservation systems are carried out by separate institutions. It served as the documentary archive on which protected-area claims were argued in a setting where no other archive of the landscapes existed. It preserved campaign history in a form that participants rather than external analysts controlled. And it constituted a readership that could be mobilised quickly when a decision point arrived, as in 2020. The implication for practice is specific: in regions where the working knowledge of a landscape is held in a language that international science does not read, publication in that language is not a communications overhead but part of the conservation apparatus, and it should be resourced accordingly.

4.3. Community Legitimacy and Conservation Outcomes

Community legitimacy operates in this material as an enabling condition rather than as an outcome variable. In each case the organisation’s standing with forest-fringe communities preceded, and made possible, the advocacy that followed: at Chakrashila, the campaign was run from a village; at Dihing Patkai, a 3-decade constituency supplied both the pressure and the readership; in primate conservation, the eco-emissary network was recruited from the villages concerned; at Chala, the community is the institution. The comparative literature reaches a consistent finding: that conservation outcomes are markedly better where communities hold substantial decision-making power and where customary institutions are recognised within the governance arrangement [20,21]. The Assam material is consistent with that finding and adds one qualification. Legitimacy was built rather than presumed over years and, in one case (Chala), with a community whose customary relation to the forest had already been disrupted. Legitimacy of this kind is therefore a product of organisational investment, not a pre-existing endowment that a project can either find or fail to find.

4.4. The Ecology of the Margins: What the Framework Adds

The conservation philosophy that emerges from Nature’s Beckon’s praxis cannot be reduced to a strong anthropocentrism or a strong biocentrism. It is biocentric in its insistence on the intrinsic worth of the golden langur, the hoolock gibbon, and the great hornbill. It is ecocentric in its emphasis on rainforest contiguity and habitat connectivity. Yet it is also unapologetically humanist. Conservation must serve, and be carried out by, the people who live with the forest. This refusal to choose between the human and the non-human is the operative core of what we call the ecology of the margins.

Three features specify the framework. First, an ecology of the margins is epistemically plural. It treats indigenous and vernacular environmental knowledge as theory in its own right, not merely as raw material for scientific processing. Datta’s literary corpus illustrates this: it is simultaneously ethnobotanical record, ecological elegy, and policy intervention. Second, an ecology of the margins is institutionally relational. Conservation outcomes emerge from institutional configurations—the Village Sanctuary, the eco-emissary network, the alliance between trained volunteers and forest-fringe communities—that integrate human livelihood and non-human flourishing. Third, an ecology of the margins is temporally patient. It works across multi-decadal time horizons because durable conservation in postcolonial frontier regions cannot be achieved by single-event mobilisations.

The framework resolves a long-standing tension in Indian environmentalism. Guha’s well-known critique of deep ecology argued that the anthropocentrism–biocentrism distinction was of “little use to the vast majority of the world’s population.” Wilderness preservation could not be pursued, he argued, without considering social equity and the integration of ecological concerns with livelihood and work [41]. Nature’s Beckon’s praxis demonstrates that biocentric commitments to species diversity and the postcolonial insistence on social equity can be productively negotiated. The negotiation does not happen at the level of theoretical reconciliation alone. It happens through forms of institutional practice that refuse to choose between human and non-human flourishing.

The implications extend beyond regional politics. Recent ecocritical scholarship has identified the integration of biocentric ethics with social-equity concerns as a defining challenge for postcolonial environmental humanities [42,45]. The Nature’s Beckon material provides empirical purchase on that challenge: the four case studies show that integration is not merely conceivable in the abstract but has been achieved in sustained institutional practice. Such grounding is rare in environmental humanities scholarship, which has tended to operate at the level of textual interpretation rather than institutional analysis, and it points toward closer dialogue between conservation social science and environmental humanities with practical conservation governance as the shared horizon. Put concisely, the ecology of the margins is less a new coinage than a name for something Assamese environmental criticism had already begun to describe, in reading Datta’s writing as a source of environmental thought rather than as descriptive background [16,17,30]. What this study adds is the connection between that thought on the page and the machinery—surveys, village sanctuaries, trained emissaries, negotiation—through which it has been converted into protected areas on the ground.

4.5. Political Opportunity and State Negotiation

This deserves a more sceptical eye, and the regional literature offers one. Studying four environmental movements in the Northeast through the idea of political opportunity structure, Rout and Yudik find that what decides success is less the force or the justice of a campaign than the shape of the political opening it meets: whether the ruling party is aligned, whether there are allies among elites, whether the state is disposed to listen [58]. Seen that way, the Dihing Patkai result of 2020–2021 was not simply advocacy rewarded. It came together with the national visibility that the Saleki controversy gave the landscape, with political support at chief-ministerial level, and, on the organisation’s account, with the two public-sector lessees agreeing in direct discussion with it to give up their claims over Joypur [40]. Nature’s Beckon’s long years of work were necessary—they built the ecological case and a public ready to act on it—but they were not sufficient; the remainder came from an opening the movement did not control. The same idea explains the partial defeat of 2004, when live mining and exploration leases, backed by well-organised capital, kept Joypur outside the sanctuary despite a campaign no less determined. As shown by the Dihing Patkai result of 2020–2021, success and failure track the political opening, and not the effort alone. This is not a peculiarity of Assam. The global analysis of environmental conflicts cited in Section 1.1 found that mobilisation halted a project in about 11% of 2743 recorded cases, and that the rate rose to some 27% where communities organised early, diversified their tactics, and went to law [18]. Dihing Patkai meets the first two conditions closely—3 decades of organising in place long before the opening arrived, and a campaign conducted simultaneously through villages, vernacular publishing, and direct dealings with the lessees—but not the third. The organisation did not litigate, and states that the lease surrenders were obtained by negotiation rather than through the courts [40]. That is the more interesting result. Where a movement has accumulated sufficient standing and sufficient documentary authority, it may secure by negotiation what the comparative literature usually attributes to litigation. The years spent before an opening appears are what make it usable when it does.

Two things follow, and they need to be held together. The first is that political opportunity does not explain every case. Chakrashila, primate conservation, and the Village Sanctuary show no identifiable political opening, and their outcomes track movement capacity, community legitimacy, and documentation instead. It is Dihing Patkai, where a discrete governmental decision was required, in which timing was decisive. The general proposition is therefore narrower than it first appears: where an outcome requires a decision by the state, long-term capacity is necessary but not sufficient and the opening must also arrive. The second is that engaging the state at all was not straightforward in a region where relations between forest administration and forest-dwelling communities have frequently been adversarial. On the available evidence, four mechanisms made it workable. The organisation entered official discussions, carrying its own survey data and documentary record, which strengthened its position as a technical interlocutor rather than only as a claimant. It worked through formal petitions and written scientific reports rather than through confrontation alone. It kept community work and official work in separate registers—the first in Assamese and in the villages, the second in English and in Dispur and Delhi. And it kept its conservation objectives separate from partisan and insurgent politics while distinguishing consistently between the forest bureaucracy, with which it cooperated, and the extractive interests operating under state licence, which it opposed. We do not generalise beyond what these sources support; the mechanisms are reported here because they are the ones the record documents.

4.6. Comparison with Global Community-Conservation Literature

Nature’s Beckon does not fit neatly into existing typologies of Indian environmental organisation. Compared to the Chipko movement of the Garhwal Himalayas, the organisation has operated through a more institutionalised form: formal registration, sustained publication, and a multi-decadal eco-emissary training programme [59]. Compared to large urban-based environmental NGOs that emerged in the 1990s with international funding, Nature’s Beckon has remained markedly vernacular in discursive register and grassroots in sociological base. Compared to the digital climate-justice mobilisations that emerged after 2018, the organisation has demonstrated the importance of long-term, place-rooted continuity. The 2020 Dihing Patkai episode illustrates this distinction between long-term institutional work and short-term digital mobilisation. The wider mobilisation that reached national attention was organisationally distinct from the rainforest campaign and focused primarily on the Saleki mining controversy [8,40]. The organisation’s long-term surveys, publications, and community work supplied an important part of the substantive case for expanded protection.

This integrative character—combining grassroots movement, formal NGO, knowledge institution, and public intellectual platform—is the most significant institutional feature of the organisation. The model invites comparison with the Singchung Bugun Village Community Reserve in Arunachal Pradesh, the Khonoma Nature Conservation and Tragopan Sanctuary in Nagaland, and the Lemsachenlok Organization. What distinguishes Nature’s Beckon from these comparators is its integration of literary production with organisational praxis. This feature has implications for replicability, discussed in Section 4.7.

Beyond India, the nearest comparators are not single organisations but whole systems of community forestry: the Mexican community forest enterprises, the Guatemalan Petén concessions, and the community forest user groups of Nepal, in each of which communities hold both use rights and management responsibility, and which supply much of the evidence in the tropical meta-analyses discussed in Section 3.6 [19,20,21]. Two differences stand out. In those systems, statutory recognition of community rights came first, and conservation outcomes followed. At Chala, the institution exists without any statutory category to occupy, which is precisely the gap the OECM framework could close. And in none of them does a vernacular literary corpus form part of the institutional infrastructure. That combination—an unrecognised institution sustained by a vernacular reading public—is what makes the Assam case distinctive, and also what makes it fragile.

The contribution should also be situated within recent comparative work on community-based conservation success. Brooks and colleagues’ meta-analysis identified four design features that consistently predicted positive outcomes across multiple national contexts: tenure security, capacity-building investment, equitable benefit-sharing, and effective external linkage to scientific and policy networks [15]. The correspondence with Nature’s Beckon’s practice varies across the four and is approximate rather than exact throughout since the predictors were derived from project data and the organisation is not a project. It is strongest for capacity-building investment, which corresponds to the eco-emissary programme, and for effective external linkage, which corresponds to the organisation’s publishing and its dealings with forest departments and researchers. The correspondence with equitable benefit-sharing is the least direct of the three: the Village Sanctuary arrangement reportedly retained livelihood and subsistence access, but the case involves no formal revenue-sharing, and no independent distributive analysis is available. Tenure security is only partially present: It remains unresolved in the Joypur extension of Dihing Patkai and has no statutory basis at Chala. The broad convergence between predictors validated on a global sample and principles arrived at independently in Assam over 4 decades is nonetheless notable and suggests that the model is not idiosyncratic. The incomplete correspondence on tenure identifies it as one important institutional constraint and a clear point for policy intervention; Section 4.8 sets out the others.

4.7. Transferable and Non-Transferable Elements

Transferability should be specified rather than asserted. Six elements of the model appear portable in principle. The eco-emissary training system is a defined procedure that does not depend on Assam. Vernacular communication as conservation infrastructure applies wherever a landscape’s working knowledge is held in a language international science does not read. Long-term organisational presence is a matter of institutional design and funding structure. Cross-scale advocacy—village, state capital, national ministry—is a repeatable pattern. Evidence-based negotiation with industry and administration is a method, not a local peculiarity. And community institution-building of the Chala type is, as Section 3.6 argues, constructible rather than only inheritable.

Five elements are not readily transferred. The regional political history that made forest custodianship a legible claim is specific. The continuity supplied by a single founder–director across 4 decades cannot be designed for, and Section 4.8 treats it as a vulnerability as well as a strength. The Assamese-language publishing and reading networks that carried the work took generations to form. The particular relationships with forest officials and with public-sector leaseholders are personal and institutional histories. The public-sector status of the Dihing Patkai leaseholders may have made negotiated engagement with government and company authorities more feasible than it would have been with some private operators, although the available evidence does not permit a firm causal conclusion. And the land-tenure conditions differ from case to case. The honest summary is that the procedures transfer and the conditions do not; policy can create some of the conditions, as Section 4.9 sets out, but not all of them.

4.8. Limits of the Framework and of the Evidence

Three tensions warrant explicit registration. The first concerns charismatic leadership. The intertwining of organisational identity with the personal authority of Soumyadeep Datta has been both a strength and a vulnerability. Continuity across 4 decades has provided the institutional memory and moral authority that has held the organisation together, but the question of succession remains open. Recent academic engagement with Datta’s corpus [13] indicates that knowledge transmission is under way, but its institutional consolidation is incomplete.

The second concerns scale. The Village Sanctuary model is built through painstaking, trust-based engagement with specific communities over multi-year time horizons. It is not obvious that this model can be scaled to landscape levels without compromise of quality. The challenge of scale is well documented in community-based conservation literature [15,43]. Nature’s Beckon’s experience suggests that durable outcomes are achievable where the underlying social conditions of community capacity and organisational continuity exist; the question of how to create those conditions where they do not yet exist remains open.

The third concerns the politics of engagement with extractive capital. The organisation’s nuanced approach—principled opposition to corporate sponsorship combined with selective dialogue during specific campaigns—has produced both successes and critiques. Critics from more radical positions may view the organisation as insufficiently confrontational; state-aligned actors may view it as obstructionist. The continuing question is whether tactical flexibility can be sustained without compromise of underlying principle.

A fourth difficulty concerns evidence, and it bears on how the claims above should be taken. The fullest record of the movement is the one the movement itself keeps, and that record does not always agree with itself: the organisation’s books give different species counts for Dihing Patkai and more than one figure and date for the declaration [51], and the commemorative and interview volumes are, understandably, admiring [38,39]. Two things follow. Credit has to be shared rather than handed to a single actor; the organisation’s own records spread it among villagers, allied groups, sympathetic officials, and, in the end, the state and its companies, and we have kept to that spread. And a declaration is not the same as protection on the ground: the sources say little about money, monitoring or governance after 2021, and the rat-hole mining that continues in the Saleki Proposed Reserve Forest is a reminder that a notification fixes a boundary on paper more easily than it holds one in the field [8,14]. These are limits of the evidence as much as of the model, and the conclusions are qualified to match.

4.9. Policy Implications for Conservation Practice

The analysis yields seven policy implications relevant to conservation practice in Northeast India and other postcolonial frontier regions. Each is stated in the form in which it could be acted on elsewhere, not only in Assam.

First, community-conserved areas require formal legal recognition. The Village Sanctuary model demonstrates that community-led institutions can deliver durable conservation outcomes, but their absence from Indian environmental law leaves them institutionally vulnerable. The Government of Arunachal Pradesh’s 2024 draft guidelines for recognition of Community Conserved Areas under the Sixth Schedule, and the Karbi Anglong Autonomous Council’s parallel initiative, represent steps in the right direction [3]. The framework should be extended across all Northeast Indian states, with provisions that recognise vernacular institutions on their own terms rather than forcing them into existing administrative categories.

Second, vernacular environmental knowledge should be integrated into protected-area management. Datta’s literary corpus and similar bodies of vernacular work in other regional languages contain substantive ecological information that is not available in the English-language scientific literature. Translation initiatives, archival projects, and inclusion of vernacular sources in protected-area management plans would substantially enhance the empirical basis for conservation decision-making.

Third, the eco-emissary training model should be replicated and scaled. Nature’s Beckon’s investment in training youth from forest-fringe communities has generated a generation of locally embedded conservation practitioners. The model provides a template that can be adapted by state forest departments, Joint Forest Management committees, and conservation NGOs across Northeast India. Implementation requires sustained institutional commitment over multi-year horizons; short-term training programmes are unlikely to reproduce its outcomes.

Fourth, conservation governance should integrate scientific documentation with vernacular advocacy. The Nature’s Beckon experience demonstrates that protected-area declarations are most durable when supported by both empirical biological surveys and accessible vernacular communication. Public interest litigation and digital mobilisation can amplify campaigns at critical moments, but they cannot substitute for sustained groundwork. Conservation policy should encourage institutional configurations that support both registers.

Fifth, regulatory frameworks must address the contradictions between extractive industry and conservation in protected-area buffer zones. The Dihing Patkai trajectory illustrates the long-term costs of allowing extractive operations to continue in violation of existing legislation. Strengthening enforcement of the Forest (Conservation) Act 1980 and the Wildlife (Protection) Act 1972, including timely judicial review of mining leases in eco-sensitive zones, would address a structural barrier to effective conservation in Northeast India.

Sixth, infrastructural development in biodiversity hotspots requires sectoral integration. The fragmentation of the Hollongapar Gibbon Sanctuary by railway electrification, the bisection of golden langur habitat by State Highway 14, and the proposed exploration in the eco-sensitive zone of multiple sanctuaries all reflect the absence of effective integration between transport, mining, and conservation policy [33,49,54]. Mandatory cumulative impact assessment, transparent eco-sensitive zone notifications, and the systematic installation of canopy bridges, underpasses, and other mitigation infrastructure should be incorporated into infrastructure-planning protocols for Northeast Indian protected-area landscapes. Biswas and colleagues’ recent peer-reviewed monitoring of 15 artificial canopy bridges installed across SH-14 near Chakrashila documented golden langur uptake in 74% of 112 observed crossings (n = 83 of 112), illustrating the kind of targeted intervention that should be scaled across the region [49].

Seventh, funding architecture for conservation should be aligned with multi-decadal time horizons. The Chakrashila and Dihing Patkai trajectories indicate that durable protected-area outcomes typically require 15–30 years of sustained advocacy, baseline science, and community engagement. Conservation funding cycles, which are typically 3–5 years, are structurally mismatched to these requirements. Bilateral donors, multilateral institutions, and Indian philanthropic organisations should explore mechanisms for longer-cycle institutional support, including endowed funding for organisations with demonstrated track records of place-based conservation work.

Which parts of the model can be adapted elsewhere, and which cannot, is set out in Section 4.7; the policy measures above are directed at the conditions rather than at the procedures, because the procedures are the part that organisations can adopt for themselves.

Implementation of these recommendations would also contribute to India’s commitments under the Kunming-Montreal Global Biodiversity Framework. Target 3 of the framework requires effective conservation of 30% of terrestrial and marine areas by 2030 through “ecologically representative, well-connected and equitably governed systems” [3]. Formal recognition of community-conserved areas of the kind pioneered by Nature’s Beckon directly advances this target. India’s recently announced commitment to identify Other Effective Area-Based Conservation Measures (OECMs) as part of its 30 × 30 strategy provides a specific institutional vehicle through which Village Sanctuaries and similar community-led arrangements could be systematically incorporated into national conservation accounting.

5. Conclusions

Four campaigns, compared as distinct types of intervention, indicate a common answer to the question this article asked. Nature’s Beckon combined community mobilisation, vernacular knowledge, scientific evidence, and engagement with public institutions in pursuing conservation outcomes, building each of these slowly and holding them together over decades, so that when a decision point arrived, the organisation possessed its own documentary record, a constituency that could act quickly, and sufficient standing to deal directly with the parties whose claims stood in the way. The Chakrashila Wildlife Sanctuary and the Dihing Patkai National Park, whose current notified areas total approximately 279.83 km², were both constituted following campaigns in which the organisation played a documented and substantial role. Where the cases differ is instructive: the two that required a governmental decision behaved differently from the two that did not.

The ecology of the margins framework is offered to name what the four cases share and what existing vocabularies do not capture. Community-based conservation describes who manages a resource; political ecology analyses power, access, and the distribution of costs and benefits; environmental justice foregrounds distribution, participation, and recognition. None of them specifies the combination this material displays: peripheral location, vernacular knowledge, and communication treated as infrastructure, leadership from outside metropolitan conservation institutions, integration of science with local mobilisation, refusal of both exclusionary preservation and extractive development, decades-long institutional presence, and negotiation across communities, state agencies, and public-sector industry. The framework’s contribution is to hold these together as a single practice that can be looked for, and examined, elsewhere.

The cases also establish a limit on what long campaigns can achieve by themselves. Sustained capacity was necessary in every case and sufficient in none where a governmental decision was required. At Dihing Patkai, the outcome came when 3 decades of documentation and legitimacy met a favourable political and administrative opening, including the reported relinquishment of claims over the Joypur Reserve Forest by two public-sector companies. The corollary matters for funders and for organisations alike: the years spent before an opening appears are what make it usable when it comes, and an organisation that cannot survive those years will not be present when it does.

On transferability, the article is deliberately specific. The eco-emissary training system, vernacular publication as conservation infrastructure, long-term organisational presence, cross-scale advocacy, evidence-based negotiation, and the construction of community institutions where custom has broken down are procedures that other organisations could adopt. Local political history, continuity supplied by a single founder, Assamese linguistic networks, particular relationships with officials and leaseholders, and specific land-tenure conditions are not procedures and do not transfer. Policy can create some of the missing conditions: legal recognition of community-conserved areas, and funding cycles matched to 15–30-year horizons, are the two that would matter most.

Four limitations qualify all of the above. The study includes no original ecological field data; ecological outcomes are assessed by synthesis of existing peer-reviewed work, and for two of the four cases, no independent assessment exists. Much of the documentary record is produced by the organisation under study, including the correspondence received during revision, and although claims of outcome have been checked against official and peer-reviewed sources wherever possible, a first-party archive cannot establish its own conclusions. Causal attribution is correspondingly limited: gazettement is an act of the state, credit is shared with communities, allied groups, officials, and, at Dihing Patkai, the leaseholders themselves, and the available sources do not permit a definitive causal claim for any single actor. And a single organisation cannot establish a general model. Comparative work on other Northeast Indian organisations, ethnographic study of the eco-emissary network, independent ecological assessment of the Village Sanctuaries, and translation of the vernacular corpus would each test what is proposed here.
