| Description: |
Common oak (Quercus robur L.) is one of the main forest-forming and economically most valuable broad-leaved tree species of Ukraine. Nowadays, there is a weakening of the stability of natural oak forests, which is the result of a complex of reasons, in particular the action of two powerful environmental factors – anthropogenic load and global climate changes, which lead to their degradation and mass drying. This is aggravated by the poor natural regeneration of oak trees. In the south of the country, natural oak groves have been preserved in ravine forests, which perform a number of important functions (soil protection, anti-erosion, water regulation, recreation, nature protection, a reserve of valuable vegetation, etc.). In connection with the above, forest taxation analysis and regular monitoring of the state of natural oak plantations in the steppe zone of Ukraine are important, in particular under different forest growth conditions, as they significantly affect the productivity indicators of stands.The aim of the study was to analyse the influence of different forest growth conditions on the taxonomic characteristics and life status of Q. robur in the Yatsevo ravine of the Dnipropetrovsk region. The survey was carried out in the Yatsevo ravine of the Dnipro district of the Dnipropetrovsk region, which is a forest reserve of national importance and belongs to the southern geographical variant of the ravine forests. The subject of the research is the forestry and taxation characteristics and the life status of oak stands of natural origin of the large southern spur of the ravine (the first from its mouth). Experimental Quercus robur L. plants grew under different forest growth conditions: in a thalweg and on a slope with a north-eastern exposure. Test site 1 was in a thalweg with a flat topography (slope no more than 5°). Forest growth conditions CL2-3 (hygromesophilic). Site 2 was located in the middle part of the steep slope (27°). Forest vegetation conditions – CL1-2 (xeromesophilic). Site 3 with xerophilic ... |
