Abstract

The woodland stage in the mixed stands of Hungarian and Turkey oak triggers ecosystem processes on account of the passage from the individual growth stage to gregarious growth. Interspecific and intraspecific competition due to density and competition for resources leads to a level of self-regulating of the ecosystem that makes each tree to behave according to the global strategy of the stand to ensure maximum stability. In the context of the current climatic changes, the Turkey oak has been affected more than the Hungarian oak, which has taken advantage of the well-known frequency rate (2-5 years), managing to install through higher natural regeneration rates. The proportioning of the mixed stands can be achieved through forestry works. For these reasons, research on the behaviour of the Hungarian oak and the changes at different growth stages is needed. Knowledge about the changes of each individual tree leads to the management of works in space and time in order to protect them in the competition with the Turkey oak.
