Site description (2007 baseline):
Site location and context
This is a beautiful steppe lake located in a valley between Bulnai and Khan Khokhii
mountains. The site comprises Oigon Lake and two nearby lakes: Shorbog Nuur; and Nogoon
Nuur. Several small rivers enter the lake from the north, creating a marshy and wet grassland delta. Some streams have stopped running because of drought, however.
The Globally Threatened Saker Falcon Falco cherrug (EN) occurs at the site. The site regularly supports at least 1% of the flyway population of Ruddy Shelduck Tadorna ferruginea, while Common Goldeneye Bucephala clangula and Herring Gull Larus argentatus occur in numbers that almost meet the 1% threshold.
Non-bird biodiversity: Grey Wolf Canis lupus, Red Fox Vulpes vulpes, Pallas’s Cat Felis manul (NT) and Siberian Marmot Marmota sibirica (EN) occur at the site.
