The Khurkh–Khuiten is a wetland complex located in the Daurian forest steppe region of eastern Mongolia, covering approximately 58,700 hectares across Khentii Province. The site comprises a network of river valleys, steppe lakes, marshes, bogs, and grasslands within the upper catchments of the Khurkh and Khuiten rivers, which feed into the Amur River Basin. This diverse mosaic of freshwater wetlands and steppe ecosystems supports internationally important populations of migratory waterbirds, including globally significant breeding populations of White-naped Crane and staging populations of Swan Goose and Hooded Crane. The site is also recognized as a Ramsar Site, an Important Bird and Biodiversity Area, and a Flyway Network Site under the East Asian Australasian Flyway Partnership.

The Khurkh–Khuiten wetlands provide essential ecosystem services, including freshwater provision, local climate regulation, and cultural services such as recreation and nature-based tourism. While the site remains relatively intact compared with other areas in eastern Mongolia, increasing pressures from livestock grazing, agricultural expansion, waste pollution, and settlement growth are affecting wetland condition and ecosystem function. Climate-related changes, including increasing drought, are also reducing wetland extent. Strengthening site management and zonation, promoting sustainable grazing practices, restoring degraded habitats, and expanding biodiversity monitoring and nature-based tourism offer key opportunities to safeguard biodiversity while supporting resilient local livelihoods.
