Sessa Orchid Sanctuary is a 100 km2 protected area of India in the Himalayan foothills in Bhalukpong Forest Division of West Kameng District, Arunachal Pradesh. It conjoins Eaglenest Wildlife Sanctuary to the southwest. It is a part of the Kameng Protected Area Complex (KPAC), which is an Elephant Reserve. [https://web.archive.org/web/20070918192235/http://www.clsp.jhu.edu/people/zak/ramana/wapLocEaglenest.htm#EaglenestMap See map]. The department of Environment & Forests has developed trekking routes for visitors to enjoy the natural habitats of orchids. There are deep gorges and valleys, high peaks and rugged terrain that are rewarding for nature lovers and adventure tourists. A nursery includes representative specimens of various orchid species of the sanctuary and a demonstration farm of Cymbidium hybrids for cut-flower production. Most of Sessa has traditionally been claimed by the Bugun tribe as part of their territory.
Geography and climate
Sessa and Eaglenest together occupy a rough east–west rectangle with Sessa occupying the north-east quadrant. The Bhalukpong-Bomdila highway (and Pakke immediately beyond) are its eastern boundary. It is bounded to the north by the Tenga River valley.Athreya Ramana M, Kartikeyan S., The Wildlife Sanctuaries in the Dafla Hills of Arunachal Pradesh [http://www.aoc.nrao.edu/~sbhatnag/Nature/warunachal/Docs/kameng94_rep.pdf Sessa Orchid Sanctuary] {{Webarchive|url=https://web.archive.org/web/20110516233457/http://www.aoc.nrao.edu/~sbhatnag/Nature/warunachal/Docs/kameng94_rep.pdf |date=16 May 2011 }} Altitude is {{convert|900|m|ft|0}} to {{convert|3250|m|ft|0}}.
Sessa and Eaglenest ridges rise to {{convert|3250|m|ft|0}} and {{convert|2700|m|ft|0}} respectively and are the first major barriers to the monsoon as it moves north from the plains of Assam. These ridges get over {{convert|3000|mm|in}} of rain on the southern slopes and about {{convert|1500|mm|in}} on the northern slopes.Choudhury A. 2003: Birds of Eaglenest Wildlife Sanctuary and Sessa Orchid Sanctuary,

Sessa is part of the Kameng protected area complex (KPAC), the largest contiguous closed-canopy forest tract of Arunachal Pradesh, which includes Sessa, Eaglenest, Pakke, Nameri, and Sonai Rupai sanctuaries and associated reserved forest blocks. The Complex covers 3500 km2 in area and ranges from {{convert|100|m|ft|0}} to {{convert|3300|m|ft|0}}3300m in altitude.Official website of West Kameng District (6/21/2007) [http://westkameng.nic.in/geography.htm Geography] {{webarchive|url=https://web.archive.org/web/20071102052829/http://westkameng.nic.in/geography.htm |date=2007-11-02 }}

Orchid Research and Development Centre
The Government of Arunachal Pradesh in the late 1970s created a post of orchidologist in the Forest Department and in 1989 established the Orchid Research and Development Centre (ORDC) at Tipi, and the Sessa Orchid Sanctuary 20 km way. The ORDC is actively engaged in exploration and collection of orchid species, cultivation in orchidaria and gardens for their taxonomic study, conservation of rare and endangered species, creation of germplasm collections and multiplication of rare species through tissue culture techniques. The ORDC discovered the following species: Biermannia jainiana, Cleistoma tricallosum, Dendrobium kentrophyllum, Epipogium sessanum, Eria jengingensis, Eria lohitensis, Gastrodia arunachalenisis and Herminium longilonbatum.ENVIS Centre Sikkim on Tourism, Physical Setting, retrieved 10/2/2007 [http://www.scstsenvis.nic.in/manipur2.html ORCHIDS-The Jewel of Arunachal Pradesh] {{Webarchive|url=https://web.archive.org/web/20090410080308/http://scstsenvis.nic.in/manipur2.html |date=10 April 2009 }}State Forest Research Institute, Department of Environment & Forests, Government of Arunachal Pradesh,[http://sfri.nic.in/p_orchidology.htm ORCHIDOLOGY-RESEARCH PAPERS] {{Webarchive|url=https://web.archive.org/web/20080620011718/http://sfri.nic.in/p_orchidology.htm |date=20 June 2008 }}
Conservation
The Critical Ecosystem Partnership Fund (CEPF), a consortium of major international and
regional organizations, has identified the Eastern Himalayan region around Arunachal Pradesh (Nepal, Bhutan and all of North-East India) as a critical global biodiversity rich area deserving of conservation focus. They identified the North-Bank Landscape (i.e. north bank of Brahmaputra, extending up the Eaglenest and Sessa slopes) and the Tawang region as worthy of particular focus.Critical Ecosystem Partnership Fund, Project database [http://www.cepf.net/xp/cepf/project_database/eastern_himalayas.xml Eastern Himalayas Region Strategic Directions] {{webarchive|url=https://web.archive.org/web/20071108132103/http://www.cepf.net/xp/cepf/project_database/eastern_himalayas.xml |date=2007-11-08 }}
