COMPARATIVE ANALYSIS OF THE DENSITY OF NATURAL REGENERATION FOLLOWING THE WOODLAND STAGE OF SEEDLINGS OF HUNGARIAN (QUERCUS FRAINETTO) AND TURKEY OAK (QUERCUS CERRIS)

The density of the naturally regenerated seedlings of Hungarian and Turkey oakdiminishes gradually following the woodland stage, simultaneously with their increase in height. The right proportioning of the mixed stands of Hungarian and Turkey oak is achieved during the regeneration process through the guided removal of fully grown trees and planting of seedlings. It is also achieved through the forestry works in their early stages of life. The promotion of the Hungarian oak in these mixed stands, in which it is negatively affected in the process of regenertaion due to climatic changes, is a constant concern of forestry, and the study of the process of natural removal in these mixed standsof Hungarian and Turkey oak trees lays the scientific foundations of the method and time of intervention. The research carried out indicates that the Hungarian oak trees are able to prevail and filter out the Turkey oak trees in the same conditions and positions. The proportioning of the mixed stands may be guided through forestry works meant to provide equal opportunities for the Hungarian and Turkey oak trees in their ealy stages of life, i.e. the thicket, saplings and poles stages. Awareness of the changes occurring in each tree can lead to adequate guidance of the works in space and time so as to enhance theHungarian oak growth in the competition with the Turkey oak
