Arunachal Pradesh is luxuriant in floristic diversity and falls under one of the World’s biodiversity hot spot “Indo-Burma”. Due to its unique phytogeography, topography and favorable climatic conditions like high rainfall and ambient humidity the state represents a high degree of species diversity and a rich store house of various economically important plant species. Upper Subansiri, is one of the 16 districts of Arunachal Pradesh, lies between 27°- 45’ N to 28°- 40’ S latitude and 93°- 12’ E to 94°- 30’ W longitude and spread over an area of 7032 sq. km adjoining to China (Tibet) border.
