Site description
Nacho-Limeking-Taksing-Majha is a large area in the north of Arunachal Pradesh in Upper Subansiri district, close to Indo-China (Tibet) border. The area is largely mountainous with a number of peaks rising over 4,000 m. The River Subansiri, which originates in Tibet flows through this IBA. Also the area is criss-crossed by number of streams and small rivers that drain into the Subansiri. Most of the forest is inaccessible and still untouched. Road network is limited and the remoteness of the site has left a large extent of habitat intact. Local inhabitants are largely of the Tagin tribe and human settlements are very minimal. In the lower reaches, below 1,500 m, elements of Tropical Wet Evergreen to Subtropical Broadleaf Forests are found. Himalayan Wet Temperate Forest, mixed with Bamboo and Cane, is found in the intermediate elevations from 1,500 to 3,000 m.

Key biodiversity

AVIFAUNA: Not much information is available on the bird life, except for the general report of Singh (1994) in which he has described birds during his various surveys of the state. However, site-wise detailed lists are not available.

A significant discovery from this area is a new monal species of the genus Lophophorus. The males of the new monal appeared very similar to the male of Sclater’s Monal Lophophorus sclateri, except for the completely white tail in the former. This was reported by local hunters of the Sarli Circle in Lower Subasiri district who also go for hunting to the Taksing area (Kumar and Singh 1999).

An interesting record of Honey guide Indicator xanthonotus, one of the two records of this species in the state is from here (R. Suresh Kumar pers. comm. 2003 )

Of the 21 species found in the Eastern Himalayas Endemic Bird Area (Stattersfield et al. 1998) 12 have been reported from this IBA. There are not many IBAs in this EBA where so many Restricted Range species are found.

Four biomes are represented in this IBA: Biome-5 (Eurasian High Montane- Alpine and Tibetan); Biome-7 (Sino-Himalayan Temperate Forest); Biome-8 (Sino-Himalayan Subtropical Forest); and Biome-9 (Indo-Chinese Tropical Moist Forest). It is not possible to list all the species here.

OTHER KEY FAUNA: Not much information is available on the fauna of this large area. However, Takin Budorcas taxicolor, Serow Nemorhaedus sumatraensis, Goral Nemorhaedus goral, Red Panda Ailurus fulgens, Capped Langur Trachypithecus pileatus and Assamese Macaque Macaca assamensis have been recorded (A. U. Choudhury pers. comm. 2003). The Bharal or Blue Sheep Pseudois nayaur was recently recorded from the Taksing area, the only other record of this species in the state, with the rest being from Tawang district in Western Arunachal Pradesh. (R. Suresh Kumar pers. comm. 2003).
