Tribal population in India constitutes about 8.6 percent of the country’s total population and there are 705 recognized scheduled tribes in the country out of which 75 are declared Particularly Vulnerable Tribal Groups (PVTGs). Tribals reside in the hilly terrains, dense forests in the remote areas perched away from the mainstream depending upon the forests for their routine needs. The interaction of tribal people with nature is intertwined with their indigenous knowledge system, the knowledge which is held by the members of a particular community and evolved through many years of regular experimentation.
