Site details
Site description: Orog Lake is a saltwater lake. Water levels vary, depending on in-flow from the Tuin River, which rises in the Khangai mountain range. The lake is frozen from November until May. The Tuin River creates a large wetland on north side of the lake. To the south, the lake is bordered by the slopes of Ikh Bogd Mountain, which support desert steppe, and give rise to several streams with associated wetlands. On the northern side of the lake, there is a wide sand dune which stretches along the shore. Orog Lake is located within the Valley of Lakes Ramsar Site.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance because it meets one or more previously established criteria and thresholds for identifying sites of biodiversity importance (including Important Bird and Biodiversity Areas, Alliance for Zero Extinction sites, and Key Biodiversity Areas)
Additional biodiversity: Globally Threatened species occurring at the site are Dalmatian Pelican Pelecanus crispus (VU), Swan Goose Anser cygnoides (VU), Pallas’s Fish-eagle Haliaeetus leucoryphus (VU), Saker Falcon Falco cherrug (EN), Lesser Kestrel F. naumanni (VU) and Relict Gull Larus relictus (VU). The site supports an assemblage of species restricted to the Eurasian steppe and desert biome. The site supports at least 1% of the flyway populations of the following congregatory waterbirds: Great Crested Grebe Podiceps cristatus; Common Shelduck Tadorna tadorna; and Ruddy Shelduck T. ferruginea. Non-bird biodiversity: No information on other fauna and fl ora is available.
