Uvs Nuur BasinAbout Uvs Nuur Basin
The Uvs Nuur Basin is a large endorheic drainage basin in western Mongolia centred on the saline Uvs Nuur (Uvs Lake). It contains a wide range of ecosystems from desert and steppe to alpine and tundra within a single basin.
The basin’s mosaic of ecosystems supports traditional pastoral use and important wildlife populations; camping and overland travel are common visitor activities but infrastructure is sparse. Seasonal access varies widely, with the summer months providing the most reliable conditions for travel and observation.
The basin is a natural landscape shaped by closed drainage and long‑term climatic and geological processes; human use has included nomadic pastoralism for centuries and localized settlement patterns adapted to the basin’s varied environments.
The basin lies in northwestern Mongolia’s Uvs Province and extends northwest into the Tuva Republic of the Russian Federation, occupying a broad inland area around Uvs Nuur.
- Large, transboundary basin: The basin covers a very large area of varied environments including deserts, steppes, alpine meadows and tundra, and extends across the Mongolia-Russia border into Tuva.
