Bhutan is listed as one among the top 10 biodiversity hot spots in the world. Bhutan has total forest coverage of over 70% of the country's total geographical area with the constitution requiring 60% of the country under forest coverage for all times to come.
The array of flora and fauna available in Bhutan is unparalleled due to conservation and its wide altitudinal and climatic range. Physically, the country can be divided into three zones: 1. Alpine Zone (4000m and above) with no forest cover; 2. Temperate Zone (2000 to 4000m) with conifer or broadleaf forests; 3..Subtropical Zone (150m to 2000m) with Tropical or Subtropical vegetation. Forest types in Bhutan are fir forests, mixed conifer forest, blue... pine forest, chirpine forest, broadleaf mixed with conifer,... upland hardwood forest, lowland hardwood forest, and... tropical lowland forests. Almost 60% of the plant species found... in the eastern. Himalayan region is present in Bhutan. Bhutan boasts of about 300 species of medicinal plants and... about 46 species of rhododendrons. Some common sights for... the visitors are the magnolias, junipers, orchids of varied hues,... gentian, medicinal plants, Daphne, giant rhubarb, the blue and trees such as fir, pine, and oaks. A wide range of rare and endangered animals can also be found frequenting the dense jungles and high mountains of Bhutan. Due to the countries conservation efforts and its unspoiled natural environment, Bhutan supports thriving populations of some of the rarest animals on earth and has thus been classified as one of the last biodiversity hotspots in the world. Some high altitude species are the snow leopards, Bengal tigers that are found at altitude ranging 3000 to 4000 meters, the red panda, the gorals and the langurs, the Himalayan black bear, sambars, wild pigs, barking deer, blue sheep and musk deer.
In the tropical forests of Southern Bhutan, one can come across clouded leopards, the one-horned rhinoceros, elephants, water buffaloes, and swamp deer. You can even find the Golden Langur, a species of monkey that is unique to Bhutan.
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’, the hub of 221 global endemic bird areas. The recorded number of bird species is over 670 and is expected to rise as new birds are discovered. In addition, 57% of Bhutan’s globally threatened birds and 90% of the country’s rare... birds are dependent on forests. Bhutan has about 415 resident bird species. These... birds are altitudinal refugees, moving up and down the mountains depending upon... the seasons and weather conditions. Of about 50 species of birds that migrate... during the winters are the buntings, waders, ducks, thrushes and the birds of prey. Some 40 species are partial migrants and they include species such as swifts,... cuckoos, bee-eaters, flycatchers and warblers. Bhutan is also home to about 16 bird species that are endangered worldwide. These... include the White-bellied heron, Pallas Fish eagle and Blyth’s Kingfisher to name a... few. Phobjikha valley in Wangdue Phodrang and Bomdeling in Trashi Yangtse are also two especially important locations of the endangered Black Necked Cranes. As one of the ten global hotspots, Bhutan is committed to preserve and protect its rich environment through its government and environmental organizations. This commitment is apparent in the fact that the kingdom has the distinct honor of being one of the only nations whose forest cover has actually grown over the years.
