Nameri National Park

It is one of the richest and most threatened reservoirs of plant and animal life in the world. The Pakhui (Pakke) Sanctuary of Arunachal Pradesh adjoins the Park on its Northeastern side. The Park extends up to east and south west bank of the river Bor Dikorai from interstate boundary at Sijussa to the left bank of Jia Bharali River up to the south bank of Balipara Reserve Forest. The area is drained by the Jia Bharali and its tributaries namely the Diji, Dinai, Doigurung, Nameri, Dikorai, Khari etc. The Park covers an area of 200 sq. km. and is augmented by parts of the Balipara Reserve Forests Area, which acts as a 64 sq. km. buffer on the opposite side of the Jia Bharali and 80 sq. kms. of the Nauduar Reserve Forests. The terrain is uneven with altitudes ranging from 80 meters along the river banks to 225 meters in the central and northern parts.

The eco-region is part of the North Bank Landscape and is an Eastern Himalayan Mega Biodiversity Hotspot. It is one of the richest areas in the world in terms of Plant Functional Type and Plant Functional Complexity. The area is influenced by the tropical monsoons, which cause rainfall to be seasonal and heavy with an average 3,400 mm of rain falling between May and September.

Climate The climate is tropical. Summers are hot and winters cold. Take cotton clothes for summers and do not forget to pack woolens during winters.
