Bhutan is a green paradise with over 70% of its land under forest cover and is home to some of the most endangered wildlife and plant species in the world. Large tracts of the forest are devoted as protected areas, parks and sanctuaries. For that very reason, Bhutan is listed as one of the ten biological hotspots in the world. Bhutan’s terrain stretches from the sub-tropical foothills in the south through temperate zone to the Alpine zone in the north, over 7,300 meters above sea level. Such drastic difference in altitude and climate makes Bhutan a fertile zone for bio-diversity.
