The Biligirirangana Hills or Biligirirangan Hills (as referred to in biology and geology[1]) is a hill range situated in Chamarajanagar District in south-western Karnataka, at its border with Tamil Nadu (Erode District) in South India. The area is called Biligiri Ranganatha Swamy Temple Wildlife Sanctuary or simply BRT Wildlife Sanctuary.[2] It is a protected reserve under the Wildlife Protection Act of 1972. Being close to the Eastern Ghats as well as the Western Ghats, the sanctuary has floral and faunal associations with both regions. The site was declared a tiger reserve in January 2011 by the Government of Karnataka, a few months after approval from India's National Tiger Conservation Authority.[3]
