Bird Conservation Nepal (Partner Designate)



Site description Dharan forests stretch from east to west in Sunsari and Morang districts, and constitute a significant portion of the forest remaining in Sunsari. Tropical evergreen tree species mixed with Sal Shorea robusta form the main vegetation type. Apart from the lower Mai valley forests, which are more degraded and fragmented, Dharan forests form the only significant area of this forest type that remains in Nepal. The forest is bisected by the major Itahari to Dharan road and lies nearly one hour’s drive from Koshi Tappu Wildlife Reserve. In addition five gravelled roads run parallel to the Dharan to Itahari road in the east linking the people of the Siwalik region with the terai.
