The coast of Baikal is bordered with rather narrow belt of the Baikal terraces (460-600 m.. .), in which the listvennichny woods prevail, sites kedrachy, pine forests, birch forests, and places – moss bogs and meadows meet. Lower and middle part of slopes of ridge (600-1250 m.. .) occupy the mountain and taiga woods. The upper bound of the wood is formed by park birch forests, pikhtach and fir groves of a podgoltsovy belt with powerfully developed vysokotravy and shrubby thickets.

The considerable spaces are occupied by almost lifeless rocks and naked stony scatterings.
