PINUS SYLVESTRIS L. NATURAL REGENERATION AFTER GRADUAL CONTINUOUS FELLING IN VACCINIOSA, MYRTILLOSA AND HYLOCOMIOSA

Abstract

Natural regeneration takes place with those tree species that have long adapted to the given conditions. The study analyzed six Scots pine stands in Vacciniosa, Myrtillosa and Hylocomiosa forest types. Sample plots (500 m2) were established five years after the gradual continuous felling. The aim of the study is to assess the natural regeneration after the gradual continuous felling in 2014 in the Vacciniosa, Myrtillosa and Hylocomiosa forest types. The number of Scots pine regrowth trees differs significantly between forest stands (p <0.05), while the average height of trees does not differ significantly between forest types (p> 0.05). The sanitary condition of Scots pine trees does not affect their natural regeneration. The most significant damage is caused by the great pine weevil (Hylobius abietis) and the ungulates (Artiodactyla).
