Аннотация: The comparison of increment dynamic of northern phytocenosis main compo-nents (trees and bushes radial increment, linear increment of mosses) has been carried out. The analysis showed that in the same year increase of radial increment in woody species was accompanied by decrease of moss linear increment, and vice versa. Stable negaПоказать полностьюtive correlation between annual linear moss increment and trees and bushes annual radial increment (r = -55-0.68, when P 0.05) was revealed in northern ecosystems (forest-tundra, northern taiga), i. e. external conditions that favour trees and bushes annual increment increase depress annual increment of mosses, and vice versa. It was also shown that during the last decade there has been observed a tendency of trees and bushes stem wood annual production de-crease and moss annual production increase, which conforms to long-term chan-ges in temperature in the region. Average values of annual production were: 0.05-0.14 t/ha for tree-stands, 0.05-0.18 t/ha for boscage, 0.66-0.54 t/ha for mosses cover.
