Forests are extensively used by rural people for subsistence in the tropics. Biomass extraction (like grazing, fuelwood collection and collection of non-timber forest produce) is arguably the most widespread form of anthropogenic pressure in developing countries like India. Persistent extraction may alter forest structure and composition, which in turn may affect the resident forest fauna. The study was carried out in Sariska Tiger Reserve that covers 866 sq. km. of dry deciduous forests in northwest India. The reserve, although earmarked for tiger conservation, has many human settlements located within its core and also around its periphery.
