Site description Uvs Lake, the largest saltwater lake in Mongolia, is fed by the Kharkhiraa, Khondlon Sagil, Borsoo, Khandgait, Torkhilog, Tes and Nariin Rivers. The lake is frozen from mid- November to mid-May. There are sandbars along the shore, with willows growing along the numerous river beds. Many small pools can be found around the lake. Many of these pools and ponds, which used to be suitable places for feeding and breeding of birds, have dried out due to drought and a warmer climate. The main land use is livestock grazing. The lake has good potential for the development of ecotourism. Unfortunately, travellers and tourists have trashed certain locations with their garbage, and willow trees have been cut by herders. Uvs Lake is designated as a Ramsar Site, a natural World Heritage Site and a UNESCO biosphere reserve.
