Site description Koyna Wildlife Sanctuary is located in the tehsils of Jawali and Patan in Satara district, western Maharashtra, covering an area of 42,355 ha and extending westwards till Ratnagiri district. Koyna WLS includes the eastern and western catchments of the Koyna Dam, which is a major hydroelectric project in western Maharashtra, currently generating 2200 MW. The reservoir of the dam is known as Shivasagar. The Sanctuary is well protected to a large extent by the Shivasagar reservoir and steep slopes. The Chandoli corridor connects this Sanctuary to Radhanagari Wildlife Sanctuary in the south. At the centre of the Sanctuary lies the historical Vasota fort, constructed during 1178-1193, which was taken over by the great Maratha warrior, Chhatrapati Shivaji in 1655 and used as a prison. During the Peshwa regime in 1817 AD, the fort was taken by the British after intense war, which resulted in its destruction. Now only ruins of the fort remain. The vegetation consists of Southern Tropical Evergreen Forest and Southern Moist Mixed Deciduous Forest, as per the classification of Champion and Seth (1968). The Sanctuary hosts a threatened tree species called Narkya Mappia foetida. Euphorbia longana and Elaecoarpus tectorius are other uncommon species. Giant trees such as Harpullia arbore and Turpunia malabarica, endemic to the Western Ghats, are commonly found in this IBA.
