Formation of an Ecotone at the Boundary of Forest and Mountain Tundra—Morskoy Ridge as an Example, Middle Part of Eastern Coast of Lake Baikal ()
ABSTRACT
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
(Pinus sibirica Du Tour, Abies sibirica Ledeb., Larix sibirica Ledeb.) out of timber stands
into the area of sub-goltsy with Pinus pumila (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.
