disturbances - Opis:
- The study was conducted in the Jata reserve (total area is 1117 ha), which is the furthest natural silver fir (Abies alba Mill.) location in north−eastern Europe. The aim of the investigation was to: (i) determine influence of stand structure and species composition on regeneration, (ii) reveal the role of canopy gaps in the forest development, (iii) recognize how the gap size determines the establishment, growth and development of tree species in the mixed stands. The investigation was carried out in chosen mixed stands with the share of fir (≤50%). All gaps defined as openings in the canopy ≥20 m2 in area that intersected the transect were localized. Natural regeneration was measured in gaps. Gaps initiated the processes of regeneration in mixed stands. It was found that gaps increased biodiversity in mixed stands – the regeneration of shrubs was possible only in gaps. Gap size did not influence the quantity of tree species regeneration. On the quantity of fir, spruce, hornbeam, sycamore and aspen influence the number of tree species in gap surrounding. Better conditions for regeneration of tree species were under the fresh mixed broadleaved site type (LMśw). The dominant tree species regenerated in gaps were hornbeam and sycamore.
