Wpływ czynników otoczenia na przeżywanie i ubywanie drzewostanów w klasach wieku w przerębowo−zrębowym sposobie zagospodarowania

The impact of natural and economic factors on the survival and decline of stands by age class was examined in 30 forest stands under a selection−clear cutting system. The results point to economic reasons, particularly a forester's decisions, as factors restraining or allowing unscheduled final cuts. Regeneration of stands is often initiated by unscheduled cuts, particularly by incidental sanitation felling. No final felling is performed in stands under regeneration with scheduled cuts concurrently restrained.
