Daurian forest steppe

The Daurian forest steppe ecoregion (WWF ID: PA0804) is a band of grassland, shrub terrain, and mixed forests in northeast Mongolia and the region of Siberia, Russia that follows the course of the Onon River and Ulz River, and part of the northwestern China. The region has been described as a "sea of grass that forms the best and most intact example of an undisturbed steppe ecosystem and is also one of the last areas in the Palearctic that still supports stable herds of larger vertebrates" in a semi-mountainous area. The area also has flat wetlands that are important to migratory birds. The ecoregion is in the Palearctic realm, with a dry-winter subarctic climate (Köppen Dwc) that borders on a very cold semi-arid climate (BSk) in its southwestern parts. It covers 209,012 km² (80,700 sq mi).
