NATURAL REGENERATION IN BEECH STANDS WITH COMPLEX STRUCTURE ON THE EXAMPLE OF THE BIESZCZADY NATIONAL PARK
Keywords: The Bieszczady National Park, beech stands of the lower-mountain zone, natural regeneration, beech, fir, sycamore, natural seedling, undergrowth
The paper presents the results of the analysis of the number of trees, construction and structure of natural regeneration layer in beech stands of lower-mountain zone (about 700–1220 MSL) in the Bieszczady National Park (BNP). The research was performed in 1993–2003 on 100 circular sample plots of the statistical- mathematical system of inventory and control of forest resources of the BNP. The obtained results prove, that the beech stands of the Bieszczady belong to the forests that regenerate very well themselves at each stage of their development, which ensures stability and sustainability in the lower mountain zone. Tree species composition of natural regeneration layer is similar to the species structure of the upper layer of the stand, while its characteristic feature is its uneven occurrence, that may be associated with differentiated lights conditions inside stands. The observations display a high variability of features of beech undergrowth, especially in case of increment of tree main stem.
