[1] The ecoregion covers the Greater Khingan mountains in Northeast China and crosses the Amur River north into the Dzhagdy in Russia.

[4][5] These climate regions tend to be found at higher elevations in the middle of continents, with wide differences between day and night temperatures.

Because the ecoregion forms a transition zone between northern (Siberian) taiga and southern (Manchurian) flora types, it features examples of both - approximately two-thirds of the 1,200 local species of vascular plants are Siberian, the other third Manchurian, Daurian and Mongolian.

The dominant trees are Dahurian larch (Larix gmelinii), with pine and spruce stands.

Mongolian oak (Quercus mongolica), hazel, alder, birch, poplars and elms also can be found at lower elevation.
