Site description Buxa Tiger Reserve is located in the northeastern corner of Jalpaiguri district. It is about 180 km from the city of Jalpaiguri and 7 km from the district headquarers at Alipurduar. The northern boundary of the Reserve lies along the international border with Bhutan. The eastern side of the Reserve forms the interstate boundary with Assam, demarcated by River Sankosh. The western and southern sides are bounded by tea gardens and agricultural fields. The core area is about 38,500 ha, which comprises 26,000 ha area of Buxa Sanctuary and 11,700 ha area of Buxa National Park. The buffer zone comprises 37,500 ha. Buxa Tiger Reserve is located at the meeting ground of three major biogeographical provinces, (Rodgers and Panwar 1988) namely the Lower Gangetic Plains, Central Himalayas and the Brahmaputra Valley. The Reserve has immense ecological and geomorphological significance. It consists of Himalayan formations of Darjeeling gneiss at an altitude of 1,800 m, the Great Boundary Fall (Godawans) lies just south of it, followed by the Siwalik Hills. Most of the area of the Reserve lies on the plains. Only the northern tracts are hilly. Many rivers and streams intersect the Reserve, the important ones are the Rydak, Jainty, Bala and Dima. Every year, flash floods cause widespread damage to forest vegetation during the monsoon. Buxa Tiger Reserve was brought under Project Tiger in 1983 and became India’s fifteenth Tiger Reserve. Buxa Tiger Reserve has a rich floral diversity. It is mainly Moist Tropical Forest and has been subdivided into eight Sub-types of Champion and Seth (1968): Sal Forest, Moist Mixed/Dry Mixed Forest, Wet Mixed Forest, Semi-evergreen Forest, Evergreen Forest, Hill Forest, Savannah Forest and Riverine Forest (Forest Department Working Plan). The most common tree species which is of great economic and ecological importance is Sal Shorea robusta. In areas adjoining rivers, Albizia lebbek, Dalbergia sissoo and Acacia catechu are the most common species, while on the hills are Morus laevigata, Ailanthus grandis, Zizyphus sp., Careya arborea and Butea monosperma. The Savannah forests is characterized by tropical trees such as Careya arborea, Dillenia pentagyna and Syzygium cumini.
