Large numbers of gulls, and migratory birds live at Uvs Nuur in summer. This immense lake (80 km wide and 80 km long) is located 28 kilometres northeast of Ulaangom. Although, at a relatively low altitude, it’s one or the coldest places in the whole country in winter. The basin' of Uvs Nuur is characterised by remarkable ecological diversity-desert, marsh, dunes, semi-desert, steppe, taiga, tundra, and glaciers-in a relatively compact zone. For this reason, it is now among the ten world sites chosen for an international research programme on biospheres.
Since 1993, the basin has acquired four strictly protected zones. The zones include Uvs Nuur, Mount Tsagaan Shuvuut, Mount Turgen and Altan Els. All the mountain valleys in the basin are rich' ill funerary sites. More than 2,000 belong to various periods (Scythian, Xiongnu, Turkish, Mongol ).
