Fauna

Bhutan’s outstanding biodiversity and ecosystems

The Kingdom of Bhutan is a small, landlocked nation nestled in the southern slopes of the Eastern Himalaya. To its north lies the Tibet Autonomous Region of China and to the west, south and east lies the Indian states of Sikkim, Bengal, Assam and Arunachal Pradesh.

The terrain is some of the most rugged in the world, characterised by huge variations in altitiude. Within the 150 miles between the southern and northern borders, Bhutan’s elevation rises from 150 to more than 7,500 metres. This great geographical diversity combined with equally diverse climate conditions contributes to Bhutan’s outstanding range of biodiversity and ecosystems.

The tiger, one horned rhino, golden langur, clouded leopard, hispid hare and the sloth bear live in the lush tropical lowland and hardwood forests in the south. In the temperate zone, grey langur, tiger, common leopard, goral and serow are found in mixed conifer, broadleaf and pine forests. Fruit bearing trees and bamboo provide habitat for the Himalayan black bear,red panda,squirrel,sambar,wild pig and barking deer. The alpine habitats of the great Himalayan range in the north are home to the snow leopard, blue sheep,marmot, Tibetan wolf,antelope and Himalayan musk deer.

Flora and birds abound with more than 770 species of bird and 5,400 species of plants known to occur throughout the Kingdom.

Conservation significance

The Eastern Himalayas have been indentified as a global biodiversity hotspot and counted amoung the 234 globally outstanding ecoregions of the world in a comprehensive analysis of global biodiversity undertaken by WWF between 1995-97. Bhutan is seen as a model for proactive conservation initiatives. The Kingdom has recieved international acclaim for its commitment to the maintenance of its biodiversity. This is reflected in the decision to maintain at least sixty percent of the land area under forest cover, to designate more than a quarter of its territory as national parks, reserves and other protected areas, and most recently to identify a further nine percent of land area as biodiversity corridors linking the protected areas. Environmental conservation has been placed at the core of the nation’s development strategy, the middle path. It is not treated as a sector but rather as a set of concerns that must be mainstreamed in Bhutan’s overall approach to development planning and to be buttressed by the force of law.

Scientific Name: Ailures fulgens
Common Name: Red Panda / Cat Bear
Local Name: Achhu Dongkar (Dzongkha)
Physical Description: medium-sized bear-like mammal with a thick rusty to deep chestnut colored coat. The muzzle, eye patches and the fronts of the large pointed ears are white and there are broad white cheek patches. The tail is long and bushy with broad brown and ginger rings. The nose is black. It walks like a bear with forepaws pointed inwards. . It has long white whiskers and an almost cat-like face. The forepaws have an extended pad on the sole and on the first digit to assist in climbing and grasping bamboo.
Size: Head & body length - 510mm - 635mm; Shoulder Height -273mm - 283mm; Tail length - 280mm - 485mm; · Weight: 3.0kg - 6.2kgs
Diet/Food: almost exclusively eats bamboo, sometimes supplement their diet during summer with fruits including berries, blossoms, fungi, seeds, acorns, eggs, young birds, small rodents, and insects. A female red panda can eat approximately 200,000 bamboo leaves in one day. (Reid et al. 1991).Red pandas spend as much as 13 hours a day searching for and eating bamboo. Only about 25 % of the already limited energy in bamboo is extracted.
Distribution in Bhutan: 1500-4000m. Pelela (Wangdue), Thrumshingla (Bumthang), Samechu (Gasa)
