Site description (2004 baseline):
AVIFAUNA: Even in this disturbed Sanctuary, 182 bird species have been reported (Singh 1994; Kumar 2003). The White-winged Duck Cairina scutulata is likely to occur in the Sanctuary or in the adjoining Drupong Reserve Forest (A. U. Choudhury pers. comm. 2003). Four species of hornbills, the Great Pied Buceros bicornis, Wreathed Aceros undulatus, Oriental Pied Anthracoceros albirostris and Rufous-necked Hornbill Aceros nipalensis occur in the area.
This site is selected as an IBA based on the presence of globally threatened species. The site lies in the Eastern Himalayas Endemic Bird Area (EBA 130). Stattersfield et al. (1998) have listed 21 Restricted Range species in this EBA. There are chances of occurrence of the Broad-billed Warbler Tickellia hodgsoni and Yellow-vented Warbler Phylloscopus cantator. As these species have a much wider winter range, they could be present here. The forests of this IBA could also have Beautiful Sibia Heterophasia pulchella. The site is also important as a centre of environmental education due to its easy accessibility for the citizens of Itanagar.
OTHER KEY FAUNA: This area is known for the presence of threatened mammals such as the Asian Elephant Elephas maximus, Tiger Panthera tigris, Asiatic Black Bear Ursus thibetanus, Gaur Bos frontalis and Wild Dog Cuon alpinus. The primates include Assamese Macaque Macaca assamensis, Rhesus Macaque M. mulatta, Capped Langur Trachypithecus pileata and Slow Loris Nycticebus coucang.
The Itanagar WLS was earlier rich in forest cover with abundant wildlife, but after the setting up of the capital city at Itanagar, primary forests have been degraded and replaced with secondary growth. The forest cover on the lower hills all along the Assam-Arunachal border, which was extensive, is now highly fragmented. Species such as Asian Elephant, which mainly occur in the lower hills, are deprived of their habitat and have now come into direct conflict with humans.
Encroachments for jhum (slash-and-burn) cultivation, heavy timber felling as permitted under the Capital complex construction, apart from illegal logging, along with the high demand for firewood and other non-timber forest produce, poses a serious threat to the standing forest cover in the Sanctuary. Hunting is a serious threat and is widespread throughout the Sanctuary. The presence of a large number of villages and a growing human population in the city nearby has led to an increased demand for wild meat. There is regular loss of livestock (Mithun, a semi domesticated cattle species) due to attacks by Wild Dogs in recent years, which could be a result of decreasing prey base in the Sanctuary. Hunting by the local people could also be the reason for the loss of prey base.
