STRUCTURE AND FUNCTIONING OF SOME FOREST ECOSYSTEMS LOCATED IN CURVATURE CARPATHIANS OF ROMANIA
Abstract
The research was carried out in the ecosystems of sessile oak and beech within Vizantea forests of Experimental Forestry Base Vidra. There were located three plots of 1 ha each, where information on the biometric features of component trees was collected. The purpose of the research was to know the structure and functioning of the sessile oak and beech crops stands in the Curvature Carpathians, as a result of their current status, in the context of sustainable forest management and climate change over the last decades. It has been shown that in the sessile oak and beech mixtures, the sessile oak retains its dominance only in the upper crown, in the middle and lower the beech has become dominant. The dominance of the beech (shade tolerant species) and the sessile oak tree (light tolerant species) in the composition of the stands influences the structure and diversity of the mixtures. From the analysis of the results so far, it can be concluded that without tending operations (helping natural regeneration, care cuts) or if there will be no major disturbance processes in the canopy, the beech will be the species that will dominate Vizantea forests in the future.
