The Nilgiris are a home to unique ecosystems, densely populated with a vast array of flora and fauna. The NBR includes a variety of interconnected habitats, including shola montane forests, tropical dry evergreen forests, and tropical dry deciduous forests. The natural habitats of these hills are famous for their richness in diversity with several rare, endangered and endemic species. This uniqueness in flora and fauna has enabled the region to be established as the Nilgiri Biosphere Reserve.
The field of biodiversity and restoration addresses questions concerning ecology and management of these endemic and economically valuable species and their vulnerable habitats. Keystone’s focus is centered upon understanding of ecosystem service, human wildlife interactions, conducting biodiversity assessments, and documenting traditional use of indigenous knowledge. The Keystone approach involves applied research, restoration efforts, outreach and knowledge networks with communities, academia, forest managers and voluntary agencies.
