tree growth response - Opis:
- The aim of this research was to assess damage to three important forest−forming trees species in the mountains – spruce, fir and larch, and to study their increment reaction to changing environmental conditions. Research concerned forests under the management of four forest districts located in the Western Sudetes (SW Poland). Index W ranging from 0 to 3 was used for the assessment of the damage to trees based on three crown characteristics: defoliation, top−crown condition and tree vitality. Trees of damage degree 2 dominated in each of the species; dying trees (degree 3) were also found. Total share of these two degrees of damage was ca 80% for spruce, 84% for fir and 74% for larch. Analysis of increment reaction of investigated species showed their similar response to changes in the environment. The increase in the share of trees showing positive responses and the decrease in the share of negative responses in the past half century, indicate an improvement in the growth conditions of spruce, fir and larch in Western Sudetes.
