Poba Reserve Forest (27°50'11"N and 95°17'45"E) is situated in Jonai Subdivision of Dhemaji District of Assam. The Reserved Forest (RF) was created in the year 1924 and covers an area of 10,221 hectares. Poba is one of the richest rain forests of North-East India in terms of the flora and fauna found in it and can be very well termed a biodiversity hotspot. The forest receives annual rainfall of 3600 mm to 4000 mm. The highest temperature so far recorded is 35°C in summer and the lowest is 7.0°C in winter.It is bounded in the  North by the foothills of the Himalayan range in Arunachal Pradesh, towards East and South are the Siang, Dibang and Lohit river systems confluencing into the mighty Brahmaputra and the Dibru-Saikhowa National Park and towards West are the revenue villages of the Jonai Sub-division of the Dhemaji district of Assam. Poba RF is an important elephant corridor linking the foot hills of Arunachal Pradesh and Dibru Saikhowa National Park via the proposed Kobu Chapori Reserve Forest. The peripheral area of the RF is inhabited by a few ethnic groups such as Mising, Bodo, Sonowal Kachari and Hajong (Rabha). These communities are dependent mostly on forest for their livelihood. Scientific research is still being carried out on the flora and fauna of the forest.
