poland - Opis:
- The aim of the research was to assess the degree of damage to spruce trees and stands and to study their growth responses to the changing environmental conditions in the Sowie Mountains (Central Sudety Mts.). To assess the degree of damage to trees, three methods based on crown characteristics were used. The types of growth responses of trees to changing environmental conditions were additionally taken into account in one of the methods. Regardless of the assessment method, spruce stands in the Sowie Mountains demonstrated a high level of damage. The poorest growth conditions were found in the period 1966−1980 when a large number of trees showed negative growth responses, indicating a decrease in radial increment. The period 1996−2010 showed an improvement in the growth conditions of trees because the proportion of trees with negative growth responses decreased, while the proportion of trees with positive growth responses increased. It was also found that the growth conditions for spruce were more favourable in the lower montane forest zone (above 600 m a.s.l.), and less favourable at the foothills (below 600 m a.s.l.), which may be caused by the competition of beech replacing spruce in the lower locations in the mountains.
