Most of the wildlife and their habitats are extremely threatened due to increasing demands on forest land and forest resources. Urbanization, expanding human habitations, encroachment of forest land, expansion of farming area, unsustainable forest resource extraction etc increase pressure and associated impacts on the forest and wild animals. Dams, mining and linear intrusions such as roads in protected areas (PAs) and in the fringes either reduce, degrade or fragment wildlife habitat leading to disruption of genetic exchanges amongst wildlife populations. According to meta-population, meta-community and island-biogeography theories, fragmentation of natural habitats could lead to extinction of many species across the globe due to loss of sub-population connectedness and inbreeding depression.
