Abstract
Non-Timber Forest Products (NTFPs) are vital sources of livelihood for forest-dependent communities across the globe. This study examined the NTFPs species (Phyllanthus emblica, P. indofischeri, and Terminalia chebula) population change determined by the dependency, disturbances, and accessibility in the dry tropical forest of Malai Mahadeshwara (MM) Hills wildlife sanctuary. The long-term monitoring population data were analyzed across three time periods; 2000-01, 2010-11, and 2020-21. The participatory research methods were used to assess the dependency and accessibility which influence the population structure. The multi-factor linkage approach was used to identify the significant drivers of population decline. The results indicated that grazing, fire, hemi-parasite infection, and Lantana invasion influenced the tree population structure and regeneration of study species. This study has also indicated variations and changes in the interrelationship among factors that have a significant role in shaping NTFPs species population structure. Multiple factor analysis determined that grazing, fire, and lantana have significant impacts on population structures, regeneration, and fruit production of NTFPs species. The study recommended that forest managers should consider a site-specific adaptive approach and multiple factors models and inclusive management tools provisioned in recent policies like the Biological Diversity Act -2002 and Forest Rights Act-2006 would hold great potential for developing sustainable use and co-management practices.
期刊介绍:
IJESD addresses matters related to environment and sustainable development, paying special attention to relevant issues in developing countries while reporting on the latest environmental trends in industrialised nations. Its range of themes encompasses ecological studies, field research, empirical work and descriptive analyses on topics such as environmental systems, environmental policies and politics, environmental legislation, environmental impact assessment, water and energy related issues, and sustainability. Other matters related to or which influence the international debate on sustainability will be also considered. Topics covered include: -Global environmental issues- Agenda 21- Energy, water, recycling, waste management- Environmental reports- Environmental policies and action plans- Environmental systems- Environmental legislation- Environmental impact assessment- Sustainable development approaches and methods.
