Elevational gradient, slope, and aspect offer a unique opportunity to explore the response of plant species under changing environmental conditions. The present study aimed analyze diversity distribution patterns with respect altitude, aspect, habitat types in Kashmir Himalayas. Considering major aspects habitats, total 123 representative sites were selected along elevational gradients for study. composition each site was studied by organized sampling following standard ecological methods. During study, 361 vascular belonging 71 families 214 genera identified area. At lower altitudes, southern drier habitats showed highest diversity. Moreover, significant amount compositional dissimilarity observed between aspects, elevation belts mainly due turnover rather than nestedness component. Further, among variables, altitude most important contributing variable, explaining greatest variation composition. paired effects explained maximum It may be concluded that floristic should not only reference but also include habitats. current will act as this direction. A similar must replicated other parts Himalayan region future improve our understanding preferences mountainous zones. This, turn, immensely helpful conservation sustainable utilization resources these ecologically fragile regions.

Forests face a variety of threats in the modern era. Agroforestry systems, both traditional and introduced, have tremendous capacity for providing sustainable resources combating impact global climate change. Indigenous agroforestry forest land-use systems are important reservoirs biodiversity conservation ecosystem services, potential contribution to livelihood security rural communities.

The present study was carried out to assess the floristic diversity and community characteristics in forest alpine zone of Gulmarg Wildlife Sanctuary (GWLS), Kashmir Himalaya. A total 123 sites were selected along an elevational gradient (2300–4200 m a.m.s.l) each every accessible aspect habitats from July 2018 June 2022. recorded 364 species vascular plants belonging 227 genera 74 families. Of species, 22 trees, 34 shrubs, 290 herbs 14 ferns. 18 communities (10 within 8 zone) identified. Within identified communities, richness ranged 44 198; tree density basal area 185–810 Ind ha−1 20.28–159.8 m2 ha−1, respectively. Density shrubs ranges 886–2040 27.79–87.75 m−2, 26–93; 1410.0–5540 31.73–102.2 zone, 0.88–1.67, 0.27–1.82 3.29–4.81, 0.73–1.33 2.21–3.69, Present presents a first comprehensive assessment GWLS, provides template, which can be replicated other protected as well unprotected areas

Ecosystem functioning and management are primarily concerned with addressing climate change biodiversity loss, which closely linked to carbon stock species diversity. This research aimed quantify forest understory (shrub herb) diversity, tree biomass sequestration in the Binsar Wildlife Sanctuary. Using random sampling methods, data were gathered from six distinct communities. The study identified 271 vascular plants 208 genera 74 families. A notable positive correlation (r2 = 0.085, p < 0.05) was observed between total density basal area (TBA), shrub 0.09), diversity (D) 0.58), 0.81), richness (SR) 0.96). Conversely, a negative found concentration of dominance (CD) 0.43). Quercus leucotrichophora, Rhododendron arboreum floribunda (QL-RA-QF) community(higher altitudinal zone) exhibited highest (568.8 Mg ha−1), while (Pinus roxburghii leucotrichophora) PR-QL (N) community (lower north aspect showed lowest (265.7 ha−1). Carbon (QL-QF-RA) (higher (7.48 ha−1 yr−1) (S) (middle south (5.5 yr−1). relationships various functional parameters such as density, significant correlations. findings revealed variations structural attributes trees, shrubs herbs across different stands along gradients. current study’s results highlighted significance wildlife sanctuaries, not only aid preservation but also provide compelling evidence supporting practices that promote planting multiple vegetation layers landscape restoration means enhance increase resilience change. Further, comprehending storage mechanisms these forests will be critical for developing environmental strategies at alleviating impacts years come.

In response to climate warming, alpine plants are migrating higher elevations and latitudes track suitable habitats. mountainous systems, the contraction of land area toward mountaintops is causing plant habitats shrink as migrate upwards. The Tibetan Plateau (TP) its adjacent Himalaya-Hengduan Mountains (HHMs) constitute world's highest flora, known "Third Pole" To predict responses change in Third Pole, we utilized four endemic Lamiaceae herbs an Ecological Niche Modeling (ENM) based on comprehensive data comprising 740 occurrence records 26 environmental variables using Biomod2. primary results revealed that climate-related factors, particularly temperature variability, shape distribution patterns study species drive them upward northward future. heterogeneous topography HHM TP leads distinct dynamics. can provide substantial new potential areas mitigate habitat loss under warming. Meanwhile, stable high-elevation regions within serve refugia ensure survival change.
