The ecoregion is known for its unique "Daurian flora", which is transient between Siberian and Manchurian floras.. There are over 1200 species of vascular plants, two thirds of which are Siberian, and one third is local Daurian, Mongolian and Manchurian. Daurian larch dominates on the altitudes of over 500 m a.s.l., forming the typical landscapes’ features. Mongolian oak, hazel heterophyllous, alder, silver and black birch, poplar, elm, Siberian apricot, Siberian hawthorn, etc., are found here. This ecoregion represents the southern range for several rare mammals of the Palaearctic fauna, including wolverines (Gulo gulo), lynx (Felis lynx), and elk (Alces alces).

Justification of Ecoregion Delineation
This ecoregion is concentrated in the Da Hinggan range in northeastern China and extends into subboreal forests with similar characteristics in the Amur basin north of the Russia border. The CVMCC (1979) Vegetation Map of China classes montane larch forests of Siberian origin (1) mixed with pine and spruce (2b, 3a) were used to form the area within China.This corresponds roughly to the Mackinnon et al. (1996) Da Xingan region of the Northeast China Province biogeographical zone. In Russia, ecoregion lines correspond to the southern taiga within the Central Siberian forest province in Kurnaev’s (1990) forest map of the USSR.
