Site description Biligiri Rangaswamy Temple Wildlife Sanctuary, is the easternmost extension of the main Western Ghats. This unique extension constitutes a live bridge between the Eastern Ghats and Western Ghats with the Biligiri Rangaswamy Temple Wildlife Sanctuary located near the middle of this bridge. Thus the biota of Biligiri Rangaswamy Temple Wildlife Sanctuary is expected to be similar to that of Western Ghats, with a significant proportion of Eastern Ghats elements as well. It is named after the Biligiri (white cliff) on which the temple of Lord Rangaswamy is located. The Sanctuary is the only large patch of forest left outside the main Western Ghats. The entire spectrum of macro-habitats is represented within the 54,000 ha of the Sanctuary. The major vegetation within the Sanctuary has been recorded (Ramesh 1989). Deciduous (moist and dry) comprises about 61%, scrub 28%, and grassland about 3.4%. Higher elevation areas are characterized by evergreen (6.5%) and high altitude sholas (0.8%) (Ramesh 1989).
