Site description The Chakrashila complex includes the Chakrashila Wildlife Sanctuary (4,556 ha) and three adjacent wetlands - Dhir, Diplai and Dakra. The Sanctuary is 68 km from Dhubri, the district headquarters, and 219 km from Guwahati city. The nearest Railway Station is Kokrajhar, which is on the broad gauge line from Howrah to Guwahati. The Sanctuary can be approached from Salkocha, a small town on the National Highway 37, from where Chakrasila is about 10 km. This IBA is an ideal spot for birdwatchers. Its biodiversity provides many niches for several species of residential birds and attracts hundreds of migratory birds. The Sanctuary is hilly, with three lakes (Dhir, Diplai and Dakra) on its southern periphery. There are three major perennial springs inside the Sanctuary: Haohaowi Jhora, Mauriya Jhora and Bamuni Jhora. The Asian Wetland Bureau, and the International Waterfowl and Wetlands Research Bureau have identified the first two lakes as internationally important sites for protection of a number of species. Dhir beel is situated 30 km from Kokrajhar town at the base of Chakrashila Wildlife Sanctuary. During the rainy season, these wetlands get connected with the Brahmaputra river. All these wetlands are rich in aquatic flora and fauna and are breeding grounds for fish. Together, these wetlands constitute more than 800 ha. The site has mainly Moist Deciduous Forest with Sal Shorea robusta as the dominant species. There are grasslands, shrubs and bamboo thickets also. This forest is richly endowed with orchids and other creepers.
