%X During last decades, new trends appeared in the ecotones of the upper boundary
of forests at the ridges surrounding Lake Baikal: ones to advance of wood species
(<i>Pinus sibirica </i>Du Tour, <i>Abies sibirica </i>Ledeb., <i>Larix sibirica </i>Ledeb.) out of timber stands
into the area of sub-goltsy with <i>Pinus pumila </i>(Pallas) Regel. up to mountain tundras. In average, this is from 100 to 200
- 300 meters in linear distance from the margin of dense timber stand. A burst of
forests renewal occurred in 1989-1995, it resulted probably from a high productivity
of the seeds of wood species due to warmer winters in 1980ies-1990ies which favoured
the formation of favourable climate-edaphic conditions for the development of forest
communities above the forests boundary on the ridges surrounding Lake Baikal.
