[3][4] The Sokhondo Reserve is in a mountainous area of the trans-Baikal region (east of Lake Baikal).
To the southeast of the Sokhondo massif is the Altan-Kyra Depression, an area of Mongolian steppe character.
[4] Sokhondo is located in the Trans-Baikal conifer forests ecoregion, a region of extensive conifer forests, primarily of Dahurian larch, in the mountains and hills east and southeast of Lake Baikal.
The light coniferous taiga is of larch (Larix gmelinii) and pine (Pinus sylvestris).
At the higher elevations the plant life is that of mountain tundra, with elfin cedar (Pinus pumila).
[8] By far the most common predator in the territory is the sable, which lives at much higher density in the reserve boundaries than in the surrounding area.
