"Allochthonous spruce stands of lower elevations in North Moravia showed a gradual worsening of health condition and decline at the end of the 20th century. At many places, birch self-seeding occurred in the opening stands or in the clear-cut areas. The plots mostly belong to small owners who left the forests unkempt and without intentional tending measures. These forest stands suffered a severe snow injury in the last years. The condition and the extent of snow injury to birch stands were assessed on the nutrient-rich sites of lower elevations in the cadastral area of Velk\u00E1 Polom. One of experimental stands was subjected to a detailed analysis of the aboveground part and root system in three sample birch trees for three groups of injuries (straight -- bending from the ground -- bending of stem). The analyzed stands differed in height (4 -- 25 m) and hence by age, as well as in the share of birch (68 -- 88 % by basal area). The proportion of injured birch trees in the stands ranged from 58 -- 97 %. T"@en . . "Mauer, Old\u0159ich" . . "2010-01-01+01:00"^^ . "290012" . "978-80-213-2098-7" . .
