摘要

非木材林产品是全球依赖森林的社区的重要生计来源。本文研究了马来maai Mahadeshwara (MM) Hills野生动物保护区热带干旱林nntfp物种(Phyllanthus emblica, P. indofischeri, Terminalia chebula)在依赖、干扰和可达性影响下的种群变化。对三个时期的长期监测人口数据进行了分析;2000-01、2010-11和2020-21。采用参与式研究方法对影响人口结构的依赖性和可及性进行评估。采用多因素联系方法来确定人口下降的重要驱动因素。结果表明,放牧、火灾、半寄生虫侵染和大柳杉入侵对研究树种的种群结构和更新均有影响。本研究还揭示了影响NTFPs物种种群结构的因素之间相互关系的变化和变化。多因素分析结果表明,放牧、火烧和大草原对nntfps物种的种群结构、更新和果实产量有显著影响。该研究建议,森林管理者应考虑采用特定地点的适应性方法、多因素模型以及最近政策(如2002年《生物多样性法》和2006年《森林权利法》)中提供的包容性管理工具,这些工具在开发可持续利用和共同管理实践方面具有巨大潜力。

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 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.
