Sessa Orchid Sanctuary

 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), an Elephant Reserve.

Sessa is noted for the occurrence of more than 200 orchid species with 5 new and endemic species. Sub-tropical types include the genera Dendrobium, Bulbophyllum, Coelogyne, Eria, Phaius, and Liparis. Since its creation in 1979, several field explorations have been carried out in the Sanctuary to study the distribution pattern of various orchid species. 

Sessa and Eaglenest occupy a rough east-west rectangle with Sessa occupying the northeast quadrant. The Bhalukpong-Bomdila highway (and Pakke immediately beyond) are its eastern boundary. It is bounded to the north by the Tenga River valley. Sessa sanctuary is drained by the Tippi Naala (Tippi river) which joins the Kameng river at Tippi village on the Bhalukpong-Bomdila highway. 

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
