Geography and climate

Eaglenest and Sessa Orchid Sanctuary together occupy a rough east-west rectangle with Sessa occupying the north-east quadrant. Eaglenest is bounded to the north by Eaglenest Ridge and the reserved forests of the Bugun community (Lama Camp area). Eaglenest adjoins Tawang district

The eastern half of Eaglenest and Sessa sanctuaries is drained by the Tippi Naala (Tippi river) which joins the Kameng river at Tippi village on the Bhalukpong–Bomdila highway. Several smaller streams including Buhiri Nadi and Dihung Nadi in the western half of the area flow down to join the Brahmaputra separately.Topographic map

Eaglenest is part of the Kameng protected area complex (KPAC), the largest contiguous closed-canopy forest tract of Arunachal Pradesh, which includes Eaglenest, Pakke, Sessa, Nameri, and Sonai Rupai sanctuaries and associated reserved forest blocks. The complex covers 3500 km² in area and ranges from 100 metres (328 ft) to 3300 metres (10,827 ft) in altitude.
Eaglenest has an unpaved road running from its base to Eaglenest pass at 2800 metres (9,186 ft) allowing good access to the entire altitudinal range, making it accessible to the military, scientists and ecotourists.

Conservation

Eaglenest is physically protected from timber and animal poaching only by its isolation and the poor quality of the one lane road leading inside it. It is administered by the Divisional Forest Officer at Seijusa who is also the Field Director of Pakke Tiger Reserve. He is assisted by a Range Forest Office in Singchung and Beat Forest Offices in Ramalingam (close to Singchung) and Khellong. In practice, the Department has no presence inside the sanctuary. The absence of any settlement inside Eaglenest has minimized any problem of hunting.

Elephants regularly move up from the Assam plains to the Eaglenest ridge at 3250 m in
summer, perhaps the highest altitude that elephants reach in India. Extensive clearing of forests
through illegal encroachments in Assam adjacent to Eaglenest has exacerbated elephant-man
conflict in the plains; it has also meant that elephants now have to stay longer in the Eaglenest area
and may lead to depletion of their food resource by dominating the rate of regeneration.
