Biligiri Rangaswamy Temple (BRT) Tiger Reserve derives its name BILIGIRI from the white rocky cliff on the top of which is a temple of Lord VISHNU locally known as Rangaswamy. It is also believed that the hill range gets its name by white mist and silver clouds that cover these lofty hills for a greater part of the year. In Kannada, Biligiri means white hills - hence the name. The Tiger reserve is located in Chamarajanagar district of Karnataka state. It covers Chamarajanagar, Yelandur and parts of Kollegal Taluks. This unique Bio-geographical entity, situated in the middle of the bridge between the Western Ghats and the Eastern Ghats in South India, was constituted as a Wildlife Sanctuary in 1974. At that time the Sanctuary comprised two Reserved Forests, namely, Chamarajanagar State Forest and BRT Reserved Forest. Subsequently in 1987 the adjoining Doddasampige Reserved Forest was added to the Wildlife Sanctuary. BRT Wildlife Sanctuary was declared as a Tiger Reserve in 2011. Total area of the Tiger Reserve is 574.82 Km². The Tiger Reserve has two sub-divisions, namely, Chamarajanagar and Yelandur sub-divisions, and comprises six ranges, namely Chamarajanagar (territorial), K. Gudi, Punajanur, Yelandur, Kollegala and Bylur wildlife ranges. The forests of BRT Tiger Reserve are principally of dry deciduous type, and are interspersed with moist deciduous, semi-evergreen, evergreen and shola patches occurring at varying altitudes. Animals including tiger, elephant, leopard, wild dog, bison, sambar, spotted deer, barking deer, four horned antelope, sloth bear, wild boar, common langur, bonnet macaque, varieties of reptiles, birds, etc. are found in the Tiger Reserve.
