| Popis: |
In the last ten years a strong intention was observed to replace spruce monocultures with mixed coniferous-broadleaved stands close to natural composition. This was accompanied by much higher rodent impact on the broad-leaved plantations than previously. To protect planted trees on forest clearings, we conducted the research in Drahany Highland (350-550 m a.s.l.) and monitored the bark damage in young beech trees, rodent density dynamics, broad-leaved trees seed harvest and a snow cover in four years period. Intensity of bark damage was not related to the rodent abundance but was influenced by high seed crop and above the average snow cover. Primary production dynamic might be a good predictive factor of broad-leaved bark damage by voles. Applicability of this method should be proved for long periods and in various natural conditions. |
