Site description The Namdapha National Park (2,59,082 ha) and Kamlang Wildlife Sanctuary (1,80,782 ha) and Kamlang Reserve Forest (78,300 ha) are situated at the southeastern tip of Arunachal Pradesh and bounded by the international boundary with Myanmar to the south and east. Namdapha lies in Changlang district, and Kamlang in Lohit. The Namdapha was declared as a wildlife sanctuary in 1972 and declared as a tiger reserve in March 1983 followed by a notification as a national park on 9 June 1983. Namdapha has been proposed as a biosphere reserve also. A part of Kamlang RF was declared as a Wildlife Sanctuary in 1989. Namdapha comprises the catchment of the Noa-Dihing river, a tributary of the River Brahmaputra. The Noa-Dihing originates in the mountains on the India-Myanmar border and flows westwards through the Park before joining the Brahmaputra river in the Assam Valley. The Kamlang is drained by rivers which are tributaries of the Lohit river. The entire area is mountainous. Lakes, locally known as 'beels', are scattered throughout the area and attract migratory waterfowl. Also in abundance are salt licks or 'poongs', of which Bulbulia is famed for its congregations of Asian Elephants and other large mammals. Details of the geology and topography are given by Ghosh (1987). The largest lake is Glao in Kamlang WLS. This 50 ha wetland is a major haunt of waterfowl (Choudhury 2002). The Dapha bum (bum = peak or ridge), the highest point in this IBA, separates Namdapha from Kamlang. This IBA is great continuous stretch of virgin forest and harbours perhaps the most diverse assemblage of species in India. Due to great altitudinal variation, diverse habitat occurs in the area, from tropical Wet Evergreen in the lower areas to subtropical and temperate forests in the higher mountains. In the Dapha Bum area, it is subalpine and alpine scrub. The geography of the area is dominated by the Dapha bum and the river valleys of the Noa-Dihing and its tributary, the Namdapha. The terrain is rugged with hardly any flat area outside the flood plains of the two rivers (Athreya et al. 1997). Namdapha TR does not have any resident human population within its boundaries. However, there are two small hamlets inside Kamlang WS. The dominant tribes around Namdapha are the Singphones, Tangsas, Lisus and Chakmas while around Kamlang there are Miju Mishmis. The climate is tropical and subtropical, with a distinct cold season from December to February. Temperature varies from 5 °C to 35 °C at lower altitudes and drops to below freezing point at higher altitudes. July and August are the warmest months. Mean annual precipitation varies from 2,500 mm to 3,500 mm, 75% of which falls between April and October, during the southwest monsoon. The rest is received from the northeast monsoon from December to March (Chatterjee and Chandiramani 1986). According to Forest Department sources, the total annual precipitation is 6,300 mm (Ghosh 1987). It rains for almost 8 months a year, with only November as a really ‘dry’ month.
