"Changes were documented in the tree species spectrum and the origin of substitute tree stands with the dominant proportion of birch Betula pendula Roth. in the eastern Kru?n\u00E9 hory Mts. (Czech Republic). Forest protection is aimed at the specification of harmful biotic, abiotic and anthropogenic air pollution factors decreasing the ecological stability of birch stands. Hypotheses were expressed and criticized associated with the disintegratioin of birch stands in the eastern Kru?n\u00E9 hory Mts. at the end of the 20th century. As for biotic factors limiting the assimilatory area gradation phytophagous species (loopers, Lochmaea capreae, Eriocrania), leaf rusts and wood-destroying fungi are studied. Impacts of abiotic factors (frost deposit, frost ribs) appear to be highly negative). The failure of birch budbreak is related to the effect of a nonspecific pollutant. The chemistry of assimilatory organs indicates the response of birch by the decrease in the content of sulphur as a response to the fall"@en . . "P(1G46002)" .
