During last decades,
new trends appeared in the ecotones of the upper boundary of forests at the
ridges surroundingLakeBaikal(Khamar-Daban and
Baikal’sky Ridge): ones to advance of wood species (Pinus sibirica Du Tour, Abies
sibirica Ledeb., Larix sibirica Ledeb., Larix
dahurica Lawson) out of timber stands into the area of subgoltsy
with Pinus pumila (Pallas) Regel. up
to mountain tundras. In average, this is from 100 to 200 - 300 meters (maximum
up to500 m) 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.
