Site description (2007 baseline)
This beautiful depression in northern Mongolia contains a group of freshwater lakes, situated in Ulaan Uul, Renchinlkhumbe and Tsagaan Nuur soums of Khovsgol aimag. The depression is about 150 km long and 40 km wide, and is surrounded by high mountains. The depression receives water from many montane rivers, such as the Bagtakh, Khug, Ar Khoridol, Arsai, Sharga, Tengis and Shishkhed Rivers, and is thus rich in wetlands and lakes. These are surrounded by diverse habitats, including dry steppe, boreal forest (taiga) and alpine vegetation. The land is used as pasture for livestock and for preparing fodder. The area is suitable for recreation and ecotourism development.
