Pakhui Wildlife Sanctuary lies in the foothills of the Eastern Himalaya, in the East Kameng District of Arunachal Pradesh. It was given its status in 1977 and was earlier part of the Khellong Forest Division. It was declared a tiger reserve in 2002. The habitat is comprised of lowland semi-evergreen, evergreen and Eastern Himalayan broadleaf forests. Over 300 species of flowering plants (angiosperms) have been recorded in the lowland areas of the park. It is also abundant in orchids. The Pakhui Tiger Reserve (PTR) is home to large cats like the tiger, leopard and the clouded leopard, and canids like the wild dog and Asiatic jackal. The elephant, barking deer, Indian bison and sambar deer are the most commonly spotted herbivores here.
