Human interference in forests is inevitable, and despite significant conservation efforts, many forest areas continue to suffer from anthropogenic pressures. The forests of the Northern Western Ghats (NWG) exhibit varying degrees of protection, including private, community, and legal frameworks. However, the tree diversity within these protection regimes remains underexplored. This study aims to assess tree diversity, composition, and structure across four protection regimes using a transect-cum-quadrat method, with four quadrats (20 by 20 m) along a single transect line. Data collected included species richness, individual counts, girth at breast height (GBH), basal area, and a combined disturbance index (CDI). Approximately 50% commonality was observed among sites across the four protection regimes. Protected Areas (PA) and Reserved Forests (RF) exhibited higher tree densities compared to Sacred Groves (SG) and Private Forests (PV). Notably, Sacred Groves, despite experiencing high disturbance levels, displayed a similar tree variety to PAs and RFs. While species composition across the four regimes was comparable, structural elements such as tree density and basal area varied significantly. Sacred Groves were predominantly characterized by older trees, whereas RFs and PAs were primarily populated by younger trees. These findings underscore the critical need for targeted conservation strategies that address the unique challenges faced by each protection regime. Enhanced conservation planning is essential to mitigate the impacts of disturbances, such as climate change and land use changes, which threaten the biodiversity of these forests. The study highlights the importance of preserving Sacred Groves and emphasizes the role of community involvement in conservation efforts to safeguard endemic species and maintain ecological balance in the NWG.
