Arunachal Pradesh known as the land of ‘dawn-lit mountains’ is a thinly populated and mountainous tract on the easternmost part of India. The higher areas, especially the peaks of the Great Himalays remain snow-capped throughout the year. Owing to great altitudinal variation, from less than 100 m to above 5000 m, five biomes are found in the state. Arunachal Pradesh forms a part of Eastern Himalaya global biodiversity hot spot and is also among the 200 globally important eco-regions. The state displays high degree of endemism and comparatively higher incidence of rare and threatened taxa. Such unparalleled distinction can be attributed primarily to the unique geophysical positioning of the state in the transition zone between the Palearctic and Orioental biogeographic regions. Being in the ecotone of the two regions, due to edge effect, the state possess biotic elements from both the regions as well as have its exclusive components and thus represents Indo-Chinese, Indo-Malayan, Indo-Burmese and Indian biotic components. This has earned the state the distinction of one of the main corridor for eastern entrant of the ‘Indian sub-region. That is why it is also referred as an active centre of organic evolution. Recognizing the importance of the state in terms of faunal diversity, Government of India established the Arunachal Pradesh Regional Centre of the Zoological Survey of India on 31st January 1983, at Itanagar under the Seventh Five Year Plan mainly to augment and explore the knowledge on faunal wealth of Arunachal Pradesh.
