Mapping studies of phytocenoses at environmental interface require a set
of approaches and methods providing obtaining of detailed information on
vegetation structure and dynamics under contrast environmental conditions.
Phytocenoses at environmental interface can be a regional model for indication
of current processes and of past changes in vegetation structure under different
environmental conditions. Mapping of environmental interface cenoses allows
revealing the peculiarities of phytocenoses structure and formation at regional
and topological level of plants organization. This is, in turn, an information
basis for identification of current processes within zonal vegetation type
(environmental zone). In the present article, the results of large-scale
mapping of phytocenoses under the conditions of interdependence of development
of zonal taiga and extra-zonal steppe at Lake Baikal western coast are
presented. We use a study method combination of geobotanical survey with
large-scale schematic mapping and vegetation mapping on the base of field
deciphering of aerospace pictures made in different years together with phytocenoses
monitoring during different seasons and years forming at the interface of zonal
forests and extra-zonal steppe.
