Site description The Mahananda Sanctuary is located on the west bank of River Teesta in the southern part of Darjeeling district in West Bengal. It was declared a sanctuary in 1976 to protect the lower catchment of the Mahanadi river, but till 1988 it was under the control of the Kurseong Forest Division, when it was transferred to the Wild Life Division. The terrain is undulating, with moderate to steep slopes and high ridges towards the north. The hill slopes descend to almost flat stretches of the terai, and alluvial plains towards the south of the IBA. The main entry point of Mahananda WLS is via Sukna, a small village 12 km from Siliguri on the Siliguri-Darjeeling road. National Highway 31 passes through the southern part of the Sanctuary. It is perhaps the largest compact block of forested habitat situated at the western end of the migratory route of the Asian Elephant Elephas maximus. A large waterbody of nearly 1,500 ha, formed after the construction of a barrage on the Teesta, falls in the buffer zone of this Sanctuary. As Mahananda extends across hills as well as plains, the forest types are quite varied. In the hills we see Sal Forest, Dry Mixed Forest and Wet Mixed Forest. In some portions, Sal Shorea robusta forms almost pure stands, with an occasional other species such as Gmelina arborea, Terminalia, Lagerstroemia parviflora, Sterculia villosa and Toona ciliata. The flood plains of rivers are covered with Phragmites karka and Saccharum munja, with scattered Bombax ceiba trees. This habitat is under human pressure and only a few undisturbed patches are left. This is the habitat of Jerdons Babbler Chrysomma altirostre and the Bengal Florican Houbaropsis bengalensis. While the former is still reported occasionally, the latter species is probably extinct in this area.
