Har Us Nuur National Park. 13/04/99; Hovd Province; 321,360 ha; 47°58'N 092°50'E. National Park. Three large but shallow lakes - Har Us Nuur, Har Nuur and Dorgon Nuur. Vast reedbeds and extensive aquatic plant communities provide a suitable habitat for a large number of breeding and migratory waterbirds, including the globally threatened Swan Goose, Ferruginous Duck, White-headed Duck and Relict Gull. Three species of fish endemic to Western Mongolia occur in these lakes. The lakes are of fundamental importance for the groundwater recharge of the area, and are of social and cultural significance because of the presence of a number of sacred places and archeological sites. Current land use around the lakes is semi-nomadic animal husbandry. Ramsar site no. 976. Most recent RIS information: 1999.
