Shey Phoksundo National Park is the largest and only trans-Himalayan national park
Shey Phoksundo National Park is the largest and only trans-Himalayan national park in Nepal. It was established in 1984 and covers an area of 3,555 km2 (1,373 sq mi) in the districts of Dolpa and Mugu in the Mid-Western Region, Nepal. The protected area ranges in elevation from 2,130 to 6,885 m (6,988 to 22,589 ft). Phoksundo Lake is the park's prominent feature, located at an elevation of 3,612 m
The flora found within the park is extremely diverse. The northern regions contain barren areas of the upper Himalayas. The Trans-Himalayan slope lands consist of some rhododendron, caragana shrubs, salix, juniper, white Himalayan birch, and the occasional silver fir dominate the high meadows of the Himalayas. Less than five percent of the park is forested, with much of it lying in the southern portion. The Suligad Vally’s flora consists of blue pine, spruce, hemlock, cedar, silver fir, poplar, rhododendron, and bamboo. The park also contains 286 species of ethnobotanical importance.
The park provides important habitat for endangered species including the snow leopard, grey wolf, musk deer, and blue sheep. Goral, great Tibetan sheep, Himalayan tahr, leopard, jackal, Himalayan black bear and yellow-throated marten are also found in the park. The park is home to six reptiles and 29 species of butterfly, including the highest flying butterfly in the world, Paralasa nepalaica. The park provides habitat for over 200 species of birds, such as Tibetan partridge, wood snipe, white-throated tit, wood accentor and crimson-eared rosefinch.
