"Abstract: The condition and snow damage to stands dominated by birch were studied in the area of interest in northern Moravia. The share of birch ranging by basal area from 68 to 88%. The stands came to existence on fertile sites through natural regeneration and exhibited growth at a level of the best site classes for the Czech Republic. The most severe snow damage to the stands was recorded at an upper stand height of 8--15 m. The extent of damages in the analyzed stands amounted to 67--95% of all trees. The unambiguously predominant type of damage was bending while breakages were recorded in only up to 4% of trees. Slenderness ratios of intact trees differed according to the age (height) of stands. The highest values of about 180 were observed in the youngest, ca. 5-year old and about 5 m high stand. Slenderness ratio values of intact trees in a 17-m high stand ranged about 100. The analyzed stands did not show differences in the slenderness ratio values of intact and damaged trees. Lower values of the ratio for solitary trees (ca. 130) in a 5-year stand were accompanied by markedly longer crowns (80% of stem) as compared with trees growing in the stand (60% of stem). Differences between intact and damaged trees within a stand of about 9 m in height consisted in the root system architecture. Keywords: birch; fertile sites; growth; natural"@en . . .
