Chiropteran fauna of Rajasthan: Taxonomy, distribution and status

Abstract

This chapter gives an intensive account of the 25 species of bats recorded so far from Rajasthan. Some species are restricted in distribution, while others are widespread in the areas where suitable habitats and food resources exist. As many as 15 species from the desert region, 17 species from non-desert region and 16 species from the Aravalli Hills have been reported, out of which seven species are common to all regions of Rajasthan. No taxa are endemic to Rajasthan. Taxonomy, distribution and status of each species have been presented separately in the text. Drastic reduction in the rich diversity and extinction of many local species in Bikaner, Jaisalmer and Jodhpur districts have been attributed to the increasing tourism and the conversion and renovation of old havelis (big villas) and palaces into hotels and lodges. The recent appearance of fruit bats and increase in their diversity due to the changing ecology of the Thar Desert after the formation of Indira Gandhi Nahar Project (IGNP) have also been described. Implementation of a ban on disturbing bat roosts in old havelis and ruins has been suggested to protect their habitat. More research initiatives need to be taken up for well-planned and detailed fi eld studies.
