Structure, growth and increment of the stands in the course of stand transformation in the Klokocna Forest Range

摘要

This paper deals with transformation of pure even-aged forest stands to uneven-aged irregular stands on an example of the Klokocna Forest Range. The fully operational management system according to principles of shelter-wood or selection systems has been executed here since 1993. An investigation of this transformation process started in 1999 and it is focused on the places with more distinct structural differences. On the basis of research analysis, it is possible to consider about the permanent uneven-aged forest stands in future here. But for successful achievement of this goal it is necessary to continue this transformation step by step for a long time. The transformation is still at the beginning and its result depends on the effort and the forest management goal and the priority of the particular forest functions.
