Classification of the Vegetation of Technogenic Landscapes of the Russian Far North
Abstract:During the past 15 years, much progress has been made in the classification of vegetation on diverse manmade/technogenic habitats (bulldozed ground, roadsides, quarries, mine dumps, terraces from open-pit mining, etc.) in the Russian Far North, ranging from northwest Siberia to Chukotka. This experience has provided the foundation for synthesizing the information into a provisional region-wide prodromus. This prodromus is based on the matherials of 11 publications devoted to the classification of vegetation of technogenically disturbed areas of the Russian Far North. All authors of the papers reviewed here used the Braun-Blanquet approach. As a result, six levels of classification are distinguished, including (from the more general to the more specific): class, order, alliance, association, subassociation, and variant (or community type). Each level of classification is related to specific spatial scales, environmental conditions, and successional gradients. Eight classes represent the vegetation of technogenic landscapes of the Russian Far North, three of them new ones identified in Yakutia. Difficulties accompanying the classification of the vegetation of technogenic habitats are discussed.
