Sikkim has one national park and six wildlife sanctuaries. These eco-reserves together constitute over 30% of the total geographical area of the state. The Temperate and Alpine eco-regions of the region are protected in one national park, Khangchendzonga National Park (1784 sq. Km) in North and West and four wildlife sanctuaries; Shingba in the North (43 sq. Km), Kyongnosla (31 sq. Km) and Pangolakha in the East (124 sq. Km) and Barsey in the West (104 sq. Km).
Shingba Rhododendron Sanctuary, located between Lachung and Yumthang, is home to the endemic Rhododendron niveum. This tree has been designated as the State Tree of Sikkim. The Kyongnosla Alpine Sanctuary, near Tsangu Lake has Budorcas taxicolor.
