Ecologo-phytocenotic characteristics of vegetation in yana river valley (north-eastern yakutia) and processes of synanthroposation thereof

The object of investigation is revelation of the processes of synanthroposation of the flora and formation of anthropogenic vegetation in different regional sub-divisions of the Yana river valley. The researchers have developed the system of ecologo-floristic classification of the natural and synanthropic vegetation of the previously syntaxonomically unstudied region, isolated a new class, three new orders, six new alliances, two new sub-alliances and thirty four association and revealed the fact that in the tundra zone synanthropic associations form at the expence of local species. Natural vegetation syntaxonomy has provided the basis for the economic typology and system of development of recommendations for rational nature management in reindeer breeding, stock breeding, herd horse breeding inclusiveAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
