Site description Mandla-Phudung, Shergaon and Kalaktang are some of the least explored tracts in Arunachal Pradesh. This region of high biodiversity is a global biodiversity hotspot (Myers 1988) as well as on Eastern Himalayan Endemic Bird Area (Stattersfield et al. 1998). Mandla-Phudung,Shergaon and Kalaktang can be treated as a unit comprising three separate but contiguous areas in West Kameng district. None of these areas are protected or even reserved forests, hence there is no well defined boundary. The forests of Shergaon are contiguous with those of Eaglenest Wildlife Sanctuary (an IBA), while Sangti Valley, another IBA, lies north of Mandla-Phudung. This IBA mainly consists of mountainous country. The lowest parts in this montane area are about 1,000 m (near Kalaktang) while the highest parts are above 3,000 m (in Mandla-Phudung area) above msl. This IBA covers part of Middle and Lesser Himalaya and some parts of the Great Himalaya. There are a number of small to medium-sized natural lakes in the higher reaches of Mandla-Phudung, ranging from tiny pools to waterspreads of more than 50 ha. These lakes are located at elevations above 3,000 m. Annual rainfall varies from less than 1,500 mm on the northern slopes (partly rain-shadow zone) to more than 2,000 mm on the southern slopes which receive heavy rainfall. The temperature generally ranges from 0 ?C in winter (minimum) to 30 ?C in summer (maximum). Breathing is difficult above 3,050 m due to low percentage of oxygen. Heavy snowfall is experienced in winter in the higher reaches (especially above 2,200 m, occasionally down to 1,800 m). The vegetation of this IBA includes Tropical Wet Evergreen Forest which occurs only in the lower areas near Kalaktang. Subtropical Forest is widespread, with both broadleaf as well as coniferous species. Broadleaf Forests occurs generally between 1,800 and 2,800 m while the coniferous forests between 2,800 and 3,500 m. Various species of oaks, magnolias and rhododendrons dominate the broadleaf forests. Three species of pines dominate the Subtropical Pine Forests, namely Pinus roxburghii, P. wallichiana and P. kesiya (mostly planted).
