Understanding the Phyllanthus and Terminalia chebula Species Population Change, Dependency and Sustainability: A Study in Malai Mahadeshwara Hills Wildlife Sanctuary, Southern India

Non-Timber Forest Products (NTFPs) are vital sources of livelihood for forest-dependent communities across the globe. This study examined NTFPs species (Phyllanthus emblica, P. indofischeri, and Terminalia chebula) population change determined by dependency, disturbances, accessibility in dry tropical forest Malai Mahadeshwara (MM) Hills wildlife sanctuary. The long-term monitoring data were analyzed three time periods; 2000-01, 2010-11, 2020-21. participatory research methods used to assess dependency which influence structure. multi-factor linkage approach was identify significant drivers decline. results indicated that grazing, fire, hemi-parasite infection, Lantana invasion influenced tree structure regeneration species. has also variations changes interrelationship among factors have a role shaping Multiple factor analysis lantana impacts on structures, regeneration, fruit production recommended managers should consider site-specific adaptive multiple models inclusive management tools provisioned recent policies like Biological Diversity Act -2002 Rights Act-2006 would hold great potential developing sustainable use co-management practices.
