Urban gardens, including family allotment gardens (FAGs) and community gardens (CGs), play an increasingly important role in urban resilience to climate change—particularly through the delivery of regulatory ecosystem services. They occupy as much as 2.6% of Warsaw’s land area and thus have a tangible impact on the entire metropolitan system. These gardens are used in different ways, and each use affects the magnitude of the provided ecosystem services. This preliminary study explores how different types of allotment garden uses affect biodiversity and ecosystem services, addressing a critical knowledge gap in the classification and ecological functioning of urban gardens. We surveyed 44 plots in Warsaw, categorizing them into five vegetation use types: turf, flower, vegetable, orchard, and abandoned. For each plot, we assessed the floristic diversity, vegetation structure (leaf area index, LAI), and six regulatory services: air and soil cooling, water retention, humidity regulation, PM 2.5 retention, and nectar provision. Flower gardens had the highest species diversity (Shannon index = 1.93), while turf gardens had the lowest (1.43) but the highest proportion of native species (92%). Abandoned plots stood out due to the densest vegetation (LAI = 4.93) and ecological distinctiveness. Principal component analysis showed that the selected ecosystem services explained 25% of the variation in vegetation types. We propose a use-based classification of urban gardens and highlight abandoned plots as a functionally unique and overlooked ecological category. Full article

Ethnobotanical knowledge and biodiversity are critical components of sustainable natural resource management, especially in regions undergoing rapid environmental and socio-economic change. In Northeast Thailand, traditional plant knowledge is deeply intertwined with local cultural identity but faces increasing threats from urbanization, agricultural expansion, and generational shifts. This study presents a floristic and ethnobotanical survey of the Khanthararat Public Benefit Forest, a community-managed remnant forest in Maha Sarakham Province, documenting 110 plant species from 42 families. The Fabaceae family was the most diverse, consistent with other tropical ecosystems. Predominantly native species (85.45%) indicate minimal disturbance, while introduced (11.82%) and endemic species (2.73%) reflect ecological complexity. Ethnobotanical data revealed 34 wild edible species, 33 medicinal plants, and 19 ornamental species used by the local community, highlighting the forest’s vital role in supporting livelihoods and cultural practices. High Use Values (UVs) for species such as Spondias pinnata and Coccinia grandis underline their dual importance in food and medicine. Informant Consensus Factor (Fic) values demonstrate strong agreement on plant use for reproductive and musculoskeletal health, reflecting well-established traditional knowledge. The findings underscore the forest’s dual significance as an ecological hotspot and a repository of cultural heritage, providing essential ecosystem services including biodiversity conservation, climate regulation, and cultural provisioning. By integrating traditional knowledge with biodiversity assessment, this study offers valuable insights for community-based conservation strategies that sustain both ecological integrity and cultural resilience in Northeast Thailand.

Despite Qatar’s depressions being ecologically significant for biodiversity in arid desert regions, they remain poorly studied. This study aimed at assessing the floristic diversity of Qatar’s depression habitat and examining the key environmental drivers shaping vegetation patterns. We applied multivariate analyses, including Canonical Correspondence Analysis (CCA) and Two-Way Indicator Species Analysis (TWINSPAN), to understand the environmental factors that shape vegetation communities and classify the depression sites. A total of 139 plant species from 35 families were recorded from 26 depression sites across Qatar. Both therophytes and chamaephytes were the dominant life forms. Biregional chorotypes were the most prevalent among phytogeographical groups. CCA indicated that grazing pressure, latitude, nitrogen concentration, clay content, and soil pH were among the variables that influenced the vegetation patterns of depressions, while longitude and soil carbon content showed marginal significance in explaining the observed floristic variation. TWINSPAN classified the sites into four distinct clusters, each associated with specific indicator species and habitat conditions. Northern depressions supported higher species richness compared to central and southern depressions, which are dominated by sandy soils and experience intensive grazing patterns that reduce the floristic diversity and limited regeneration of key shrubs such as Vachellia tortilis (Forssk.) Galasso & Banfi. This study helps fill a critical knowledge gap about Qatar’s depression habitat, enhancing efforts to conserve these vulnerable ecosystems, identify ecological threats, and better understand patterns of species distribution across arid landscapes.

Bryophytes’ adaptability and stress resistance make them excellent colonizers. Moreover, bryophytes are key components of almost all terrestrial ecosystems from aquatic to arid to freezing cold. Bryophytes are also unique models to study adaptation and stress resistance in plants. Bryological studies in the Mediterranean area are mainly floristic-oriented, and consequently, the knowledge of the autoecology of the species inhabiting Mediterranean islands and islets is very scarce. The aim of this study is to evaluate bryophyte diversity in a number of islands and islets surrounding the Italian peninsula, Sicily and Sardinia. Moreover, based on the geographical and environmental features available for the studied islands, we analyze the role of different ecological variables (such as the islands’ area, insularity degree, altitude, and substratum type) in shaping bryophytic species richness and diversity. In the present study, ecological indicators adapted to Mediterranean bryophytes were also used to describe from an ecological and functional viewpoint the species inhabiting the studied islands and to explore to what extent the islands’ features have had a role in shaping the ecological features of the bryophytic floras inhabiting them. Within this study, an updated overview on the floristic richness and diversity of the small islands surrounding the Italian peninsula, Sicily and Sardinia was presented. The subject of the discussion was the island-related floristic and ecological differences as well as the drivers of these differences. Full article

Montenegro, with approximately 3600 vascular plant taxa, represents one of the floristic diversity centers of the Balkan Peninsula and the Mediterranean region. According to our current knowledge, about 80 to 100 orchids, including species, subspecies, and hybrids, occur in this country. To refine the understanding of orchid diversity in Montenegro, extensive fieldwork and herbarium revisions were conducted. As a result, ten new orchid taxa were recorded in Montenegro for the first time. These include Epipactis helleborine subsp. distans, E. leptochila subsp. neglecta, Gymnadenia densiflora, Neotinea ustulata var. aestivalis, Ophrys archipelagi, O. grammica, and Pseudorchis albida subsp. tricuspis. In addition, one intergeneric hybrid, ×Serapicamptis rousii, and two intrageneric, Anacamptis ×nicodemi and A. ×olida, were found. Distribution data, ecological preferences, and population sizes for newly registered taxa in Montenegro have been given. This study underscores the great potential of the flora of Montenegro for discoveries in the orchid world. Full article

Palynology is an invaluable tool for reconstructing past biodiversity in agrarian and cultural landscapes and for understanding present-day environmental assets. By analysing past evidence, rooted in botanical knowledge, we can foresee future environmental trends. Italy, at the centre of the Mediterranean, is one of the richest countries in terms of pollen analyses from archaeological sites and therefore is particularly suited to reconstructing human–environment relationships and anthropogenic impacts on flora over time. We selected data filled in the database BRAIN. This paper presents new elaboration on pollen data from 14 published and unpublished archaeological sites, showing past plant diversity and land management in prehistorical and historical contexts of southern Italy. Overall, the research demonstrates that the floristic palaeodiversity, as revealed through the group-equalised indicator species analysis, supports and validates the palynological data on the flora of Campania, Basilicata, and Sicily. The study highlights the presence of ubiquitous pollen taxa in anthropogenic environments and explores the connection between past and present plant diversity. Full article

Floristic and biodiversity knowledge play a crucial role in ecosystem conservation and sustainable land management, particularly in urban-rural contexts that can serve as biodiversity reservoirs, hosting species of high biogeographic value. Focusing on the new municipality of Misiliscemi, established in 2021 in Sicily and now facing the challenge of developing new management strategies, this study provides fundamental knowledge on the plant biodiversity of the area and explores how the integration of floristic and environmental data can guide territorial planning strategies aimed at preserving natural capital and ecosystem services. The research, based on field surveys conducted over many years, taxonomic identification of species, analysis of biological forms and chorological data, evaluation of ecological indicators, and GIS-based habitat mapping according to the EUNIS classification, has made it possible to obtain a comprehensive dataset. The results of this work led to the identification of 623 taxa, recording new findings for the Sicilian flora, including both native and alien species, which represent primary biodiversity data crucial for plant resource management. In addition, 42 habitat types were mapped, highlighting that approximately 80% of the territory is occupied by vegetated man-made habitats. Despite anthropogenic pressures and landscape modifications, Misiliscemi retains significant plant biodiversity, including habitats and species of conservation interest, that represent a vital resource for natural capital and ecosystem services. This knowledge base, in addition to constituting the scientific foundation upon which this young municipality can develop an urban planning strategy aimed at achieving sustainable local development, also represents a methodological approach that highlights how basic knowledge of urban biodiversity should be considered a crucial aspect of sustainable urban planning worldwide.

Incarvillea semiretschenskia (B. Fedtsch.) Grierson is listed in the Red Data Book of Kazakhstan as a rare relic, narrowly endemic species of the Shu-Ile low mountains (Kazakhstan). The aim of this research was to advance our knowledge of the ecological conditions of its habitats, the floristic composition of plant communities, and molecular phylogeny, as well as to identify threats to the species’ existence. The ecological conditions of I. semiretschenskia habitats are rocky slopes and intermountain valleys of the low mountains in the altitude range from 812 to 1075 m asl with light chestnut mountain soils of little development, having a light granulometric composition and containing insignificant amounts of organic matter. We revealed 164 species of vascular plants in the communities of I. semiretschenskia, including five endemics and five species from the Red Data Book of Kazakhstan. Anthropogenic factors associated with grazing, fires, and limestone mining were identified as leading to a decrease in the number and density of populations. New insights into the relationship and time of diversification in the genus Incarvillea are gained through the use of several accessions of I. semiretschenskia and I. potaninii Batalin in the phylogenetic study. Preliminary fingerprint analysis shows relatively high genetic variability within populations of I. semiretschenskia. This unique relic species has survived since the Miocene epoch and exists to this day only in the Shu-Ile low mountains. To preserve this rare species, measures are proposed to create plant micro-reserves to provide ex situ collections and ensure future in situ restoration efforts. Full article

Despite the wide amount of scientific contributions published on alien plant species, their diffusion dynamics, and their interactions with native taxa, it is increasingly difficult to slow down their spreading and their negative impact on habitats. Last recent years, in fact, a sharp rise in the number of new alien plant taxa introduced in Italy and Europe has been recorded. The aim of this work is to investigate most of the Italian territory in order to verify whether this alarming trend is still underway. Specimen collections and/or observations of alien plants have been performed in as many as 12 Italian regions. All the collected specimens are stored in public or private herbaria. Taxa have been identified according to the literature from the countries of origin of the investigated taxa, while the nomenclature followed the current international references. Updates on 106 taxa are reported. In particular, among 117 new records, 89 are first records, 27 are changes to status and there is 1 extinction. Seven new taxa for Italian alien flora are reported, two of which are new to Europe. The administrative regions with the highest number of records are Calabria (48), Sardegna (17) and Sicilia (15). Five of the surveyed taxa, for the first time, have been considered invasive aliens to Italian territory. The unfrequent amount of original results provided by this work, over the simple importance of data itself, proves how floristic investigation, still today, represents one of the most effective tools in broadening the current knowledge about alien taxa and their dynamics.

Urbanization and urban regeneration can significantly impact cultural heritage, but a greater knowledge of the past natural and historical features is needed to value the past and understand the present. The lost Villa Peretti Montalto in Rome, once located in the area that corresponds to the current front side of Termini station, deserves great attention due to its cultural value. This work aimed to provide a floristic and functional reconstruction of the gardens of the villa during the XVI and XVII Centuries. From several bibliographic and iconographic sources, a critical analysis and interpretation of plant names was conducted. A list of 87 species and their location in the different garden sectors, during different periods with their specific uses, is provided. The arboreal design was made by classical species in the Roman context, like Cupressus sempervirens, Pinus pinea, Quercus ilex, and Ulmus glabra. In addition, ancient lost varieties of fruit trees (mainly Pyrus communis and Ficus carica) and several species of conservation interest were found. The knowledge of the ancient flora in historical gardens could be a key tool in urban greenery planning and touristic and cultural valorization. Full article

We present a floristic–vegetational study on a plant community dominated by Geranium argenteum in the Sibillini Mountains (Central Apennines), at the southern limit of its distribution in the Apennines. It is a rare pioneer community located at an elevation of about 2100 m a.s.l. with northern exposure on the fractured rocky ridges and at the edges of the rocky detrital valleys on lithosol, with a prolonged presence of snowpack and gelifraction processes. The results of the phytosociological analysis allow us to propose the new Festuco italicae-Geranietum argentei association referred to as the Leontopodio nivalis-Elynion myosuroidis alliance (Carici rupestris-Kobresietea bellardii class). The comparison with the Alpine and the Northern Apennines phytocoenoses characterized by Geranium argenteum allows us to provide a new interpretation of the syntaxonomical framework concerning the Geranium argenteum communities within its Alpine–Apennine range in light of the new data presented in this paper. The new Festuco italicae-Geranietum argentei association represents a further contribution to the knowledge of the relict alpine vegetation of the Leontopodio nivalis-Elynion myosuroidis alliance in the Sibillini Mountains and thus in the Central Apennines. Finally, habitat monitoring will be essential for assessing the impacts of climate change on this fragile and narrowly restricted plant community. Full article

A significant challenge in community ecology is the establishment of ecological baselines, which permit the evaluation of the variations in ecological dynamics at different temporal and spatial scales. To our best knowledge, few studies have been conducted in the forest openings of Mt. Parnon to establish a baseline for future monitoring. Hence, a floristic study of the herbaceous plant species composition, diversity, cover, and biomass was conducted in the forest openings of the Mt. Parnon-Natura 2000 Site in Greece to develop an ecological baseline that could be utilized in decision making for conservation and the sustainable use of forest biodiversity and ecosystem services in the forest ecosystem of Mt. Parnon. In the spring season, a thorough floristic survey was performed on Mt. Parnon for two consecutive years, 2021 and 2022. Herbaceous plant composition, diversity, cover, biomass, and plant indicator species (indicator value analysis) in the forest openings of Mt. Parnon were assessed. In the studied area, 63 plant species belonging to 58 genera from 20 families were recorded. The most numerous families were Asteraceae and Poaceae, followed by Fabaceae. Variable plant diversity, herbaceous plant cover, and produced biomass were recorded in different sites. It is noteworthy that some plant species could be regarded as indicators of the sites in the study area [Geranium molle L., Cerastium candidissimum Correns, Vicia villosa Roth, Euphorbia myrsinites L., Odontarrhena muralis (Waldst. & Kit.) Endl., Medicago lupulina L., Lotus corniculatus L., Crepis fraasii Sch. Bip., Bellis sylvestris Cirillo, and Trifolium stellatum L.], and information about these indicators, including Ellenberg type indicator values, is also provided. This study contributes to the understanding of the relevant ecological topics and provides key elements that could be utilized in decision making for the conservation and sustainable use of forest biodiversity and ecosystem services on Mt. Parnon. Full article

Weed management is not yet environmentally, agronomically, economically and socially sustainable in olive orchards. It is necessary to study appropriate integrated weed management systems (IWMSs) based on the knowledge of weed population and effects of weeding practices over time. The aim of this study was to evaluate the effects of different weed managements on seasonal floristic composition of a super high-density olive orchard, also exploiting the essential principles of an IWMS. Five weeding techniques were compared: chemical control (CHI), mowing (MEC), plastic (nonwoven tissue, TNT and polyethylene, PEN) and organic (with de-oiled olive pomace, DOP) mulching. Weed monitoring was carried out on six dates in a three-year period. The infestation of each of the main 18 weed species recorded (%) and the total infestation (%) on each monitoring date were determined. Results underlined that all weeding practices investigated in this multi-year study affected the floristic composition, weed characteristics (hemicryptophytes, cryptophytes and therophytes) and seed bank. TNT and PEN were the most effective methods for weed management. Particularly, total infestation coefficient was significantly lowest when plots were managed with TNT (13.91%) and PEN (14.38%) and highest for MEC (141.29%). However, DOP also significantly reduced infestation compared to CHI and MEC. Therefore, DOP could constitute an excellent strategy for weed management in super high-density olive groves, since it also has the possibility of distributing mulching materials in a mechanized way in field and can result in improvement of soil fertility and the possibility of valorizing waste. Further studies should be carried out to investigate the mechanism of action (physical and allelochemical) of de-oiled pomace or other organic agro-industrial materials and the recovery time of these mulching materials in super high-density olive orchards.

The recent Glasgow Climate Pact has recognized the contribution of ecosystems as sinks and reservoirs of greenhouse gases and their importance to achieve the objective of a maximum temperature increase of 1.5 °C. Thus, the knowledge of the long-term storage capacity of the soil organic carbon (C) in forest soils, and the driving factors, are considered of great importance for the mitigation of global climate changes. A database of published data in a ‘grey’ Greek bibliography, concerning the long-term storage of soil organic C in soil profiles for Greek forests, was compiled, including 307 full soil profiles, distributed between 21 types of forest ecosystem throughout the country (Greece). The data collected concerned the amount of long-term stored carbon in the full soil profile, per soil horizon, up to the uncracked bedrock. These also contained information on the sampling location, the type of forest ecosystem, the soil depth, the type of land management, the forest origin, the floristic zone, the altitude, and the climate type. According to the results analysis, the average soil organic C stored was 108.19 Mg ha⁻¹, and ranged greatly between 11.49 and 409.26 Mg ha⁻¹. The type of forest ecosystem, soil depth, land management practices, forest origin, floristic zone, and climate type played an important role in the carbon sequestration process, greatly influencing the long-term amount of stored carbon. Under the demands for mitigating climate change and reducing the rates of global warming, data evaluation indicates the directions to be followed for increasing the long-term storage of carbon, named systematic forest management, and the exclusion of the drivers responsible for the low carbon storage of soil, such as human pressure and overgrazing. Restoration actions such as reforestation and rehabilitation of the degraded forest ecosystems, which were found to store low carbon amounts, can be also considered as effective tools for increasing the long-term carbon storage in forest ecosystems.
