The main lakes are Khar Us Nuur, Khar Nuur and Dörgön Nuur. The national park was established in 1997, and then designated as a Ramsar (wetland of international significance) site in 1999. The lakes have the largest reed beds in Central Asia. Surrounded by desert landscapes, it is surprising to find that rare wild boars can survive in the reeds. Saiga antelope, though rare, have increased in later years, migrating through the park. Nearby Jargalant Hairkhan Mountain have Snow Leopards, Argali Sheep and Siberian Ibex. The mammals are, however, difficult to observe. For this reason, the many species of birds, the landscape and encounters with local nomads are the main attractions here.
Approximately 20 000 people live in and adjacent to Khar Us Nuur National Park. Most are nomads with some 200 000 livestock. Their migrations here may cover a fairly long distance, as precipitation is on average only 120mm per annum and sometimes as little as 70mm. Also, the lakeside has too many mosquitoes in the summer, why the herders usually take their livestock to higher altitudes.
