Bhutan is located in the southern slopes of the eastern Himalayas, the kingdom is landlocked between the two great Asian civilizations, Tibet (China) to the north and the Indian States of Assam, Arunachal Pradesh, Sikkim & West Bengal in the East, West, & South. The country lies between latitudes 26′ 45’N & 280″ 10’N, and longitudes 88′ 45′E & 92′ 10’E. It has a total area of 38,394 square kilometres.
Bhutan’s physical geography consists mostly of steep and high mountains crisscrossed by a network of swift rivers, which form deep valleys before draining into the Indian plains. The land rises from 200 meters above sea level in the southern foothills to 7000 meters high northern mountains. Within this latitudinal range are found a diverse biodiversity rich enough to be considered as one of ten global environmental ‘hotspots’. About 72.5 per cent of the area is under forests, and it is constitutional mandate to maintain 60 per cent forests cover for all times to come.
The climate varies hot subtropical in south to cold alpine slopes in the north. Human settlement is confined mostly to interior river valleys and a swath of southern plains; nomads and other tribes live in the north, raising sheep, cattle and yaks.
Bhutan straddle two major bio-geographic realms, the Indo-Malayan realm consisting of the lowland rain forests of South and Southeast Asia and the Pale-arctic realm consisting of conifer forests and alpine meadows of northern Asia and Europe.
