Physically, Bhutan can be divided into three zones: Alpine Zone (4000m and above) with no forest cover; the Temperate Zone (2000 to 4000m) with conifer or broad leaf forests; and the Subtropical Zone (150m to 2000m) with Tropical or Subtropical vegetation. Because of its wide attitudinal and climatic range, the flora and fauna is diverse and rich in Culture.
Forest types in Bhutan are Fir Forests, Mixed Conifer Forest, Blue Pine Forest, Chir pine Forest, Broad leaf mixed with Conifer, Upland Hardwood Forest, Lowland Hardwood Forest, and Tropical Lowland Forests. Almost 60% of the plant species that is found in the eastern Himalayan region can be found in Bhutan as well.

In the tropical forests of Southern Bhutan one can come across the clouded leopards, the one horned rhinoceros, elephants, golden langur that is unique to Bhutan, the water buffaloes and the swamp deer.
Bhutan also has a great variety of bird species. It is recognized as an area of high biological diversity and is known as the East Himalayan ‘hot spot’ situated as it is at the hub of 221 global endemic bird areas. The recorded number of bird species is over 675 and there are chances that this number could still go up.
In addition, 57% of Bhutan’s globally threatened birds and 90% of the country’s restricted rare birds are dependent on forests. Bhutan has about 415 resident bird species. These inhabitant birds are attitudinal refugees, moving up and down the mountains depending upon the seasons and weather conditions. Of about 50 species of birds that migrate in winters are the buntings, waders and ducks, thrushes and the birds of prey. Some 40 species are partial migrants and they include species such as swifts, cuckoos, the bee-eaters, fly catchers and the warblers. Over 70% of Bhutan’s land area is still under forest cover.Many apart of the country have been declared as wildlife reserves and are natural habitats of rare species of both Flora and Fauna .
Bhutan is also home to about 16 bird species that are endangered worldwide. These include the White bellied heron, Pallas Fish eagle, Blyth’s King fisher to name a few. Phobjikha valley in Wangdue Phodrang and Bom-deling in TrashiYangtse are also two important places in Bhutan that is visited by the endangered Black Necked Crane.
