Special Issue Information

Dear Colleagues,

Estimates suggest around 500,000 land plant species, exceeding the diversity of birds and mammals, and rivaled only by fungi and beetles. The diversity of plant species is an elemental component of ecosystems worldwide, playing a fundamental role in maintaining ecological balance and sustaining life on Earth. Plant species diversity refers to the variety and abundance of plant species in a given area and is essential for the stability of ecosystems: diverse plant communities are more resilient to environmental changes such as extreme weather events, diseases and invasive species. They provide essential ecosystem services such as soil stabilization, water purification and carbon sequestration. However, in recent decades, habitat loss, fragmentation, and degradation, overexploitation, pollution, invasive species and climate change have led to a significant loss of plant diversity. Despite its importance, plant species diversity is threatened by habitat loss and fragmentation, pollution, climate change and invasive species.

In this context, the conservation of plant species diversity requires coordinated efforts at local, national and global levels, such as habitat protection and restoration, sustainable land-use management and invasive species management.

We invite manuscripts aimed at highlighting the importance of plant species diversity in maintaining ecological balance and sustaining life on Earth. In addition, contributions may highlight threats to plant diversity such as deforestation, habitat destruction, pollution and climate change. They may further advocate the conservation of plant species diversity through coordinated efforts at different levels, including habitat protection and restoration, sustainable land use and invasive species management.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: 

  • Plant species diversity;
  • Threats to plant diversity;
  • Conservation of plant species diversity.

We look forward to receiving your contributions.

Climate change is altering environmental conditions, which can, in turn, change the geographic distribution and flowering patterns of plant species, affecting both the plants themselves and their pollinators. The responses of melliferous plant species to climate change in southeastern Mexico are poorly understood, which hinders an accurate assessment of their vulnerability and the resulting ecological impacts. As understanding the mechanisms that influence the distribution and susceptibility of these species is essential, the present study examined how climate change affects their potential distribution areas and spatial distribution patterns. This information will serve as reference data for the implementation of conservation strategies and inform the selection of species for reforestation. Ecological niche models were used to estimate the potential distributions of 92 melliferous species under both current environmental conditions and two climate change scenarios projected for the 2041–2060 period (SSP245 and SSP585). Changes in distribution patterns were then assessed by evaluating the range size of each species and analyzing the spatio–temporal trends in species richness. The results revealed that suitable habitats shifted for approximately 80% of melliferous species, with more significant habitat loss observed under the SSP585 scenario than under SSP245. Although a significant decrease in melliferous plant species richness was expected in future scenarios, richness was slightly higher (by 10% for SSP245 and 5% for SSP585) than that observed under current environmental conditions. Under SSP245 conditions, species richness areas expanded to encompass almost the entire region, although this contrasted drastically with the SSP585 scenario, where areas with the highest concentration of species richness contracted significantly and areas with low species richness expanded. These projections are of potential use for conservationists and environmental management authorities, providing crucial insights into the future distributions of several melliferous plant species in the region, the potential impacts of climate change on their habitats, and the vulnerability of threatened species to changing climatic conditions.

This study assesses the conservation effectiveness of 21 protected areas (PAs) in Northern Morocco, comprising 3 parks and 18 Sites of Ecological and Biological Interest (SBEIs), against five major landscape pressures (LSPs): deforestation, infrastructure extension, agricultural expansion, fires, and population growth. We propose a novel quantitative methodology using global remote sensing data and exploratory spatial data analysis (ESDA). Data were sourced from Global Forest Change (GFC), Global Land Analysis and Discovery (GLAD), Burned Area Product (MODIS Fire_CCI51), and World Population datasets. The combined impact of the five LSPs was measured using a cumulative effect index (CEI), calculated with the Shannon–Wiener formula at a 1 km2 scale. The CEI was analyzed alongside the distance to the PAs’ network using Moran’s index, identifying four spatial association types: high–high (HH), high–low (HL), low–low (LL), low–high (LH), and non-significant (NS) cells. This analysis defined four zones: inner zone (IZ), potential spillover effect zone (PSEZ), statistically non-significant zone (SNSZ), and non-potential effect zone (NPEZ). Conservation effectiveness was quantified using the conservation ratio (CR), which compared the prevalence of LL versus HL units within IZs and PSEZs. Four disturbance levels (very high, high, medium, and low) were assigned to CR values (0–25%, 25–50%, 50–75%, 75–100%), resulting in sixteen potential conservation effectiveness typologies. Initial findings indicated similar deforestation patterns between protected and unprotected zones, with wildfires causing over half of forest losses within PAs. Conservation effectiveness results categorized the 21 PAs into nine typologies, from high conservation to very high disturbance levels. A significant positive correlation (71%) between CRs in both zones underscored the uniform impact of LSPs, regardless of protection status. However, protected natural area zones in the parks category showed minimal disruption, attributed to their advanced protection status. Finally, we developed a methodological framework for potential application in other regions based on this case study. Full article
