Information on diversity and distribution of faunal resources at habitat, local and regional scale is the key to biodiversity conservation in India. Thus surveying, collection and inventorisation of faunal resources becomes imperative to generate baseline data on genetical data, species and their macro- and microhabitat in ecosystem diversity. The local database thus generated helps in developing a regional / national database on biodiversity, which in turn facilitates compilation of information on distributional pattern of faunal wealth. Furthermore, it also lends a hand in developing models for conservation strategies of endemic and threatened fauna. Since conservation of the entire range of species is neither practical nor possible, such preliminary studies help in identifying the keystone and umbrella species. The protection and conservation of such species ensures the survival of all the species in the area. In view of this the inventorisation of the faunal resources of Radhanagari Wildlife Sanctuary was undertaken by the scientists of the Western Regional Centre, Zoological Survey of India, Pune, during the period 2007-2010 as part of series on faunal resources of Protected Areas.
