Abstract:
This paper presents research into the elements of the so-called simple structure and some elements of the so-called spatial stand structure in pure mature stands of the sessile oak in the continental part of Bosnia and Herzegovina. Temporary test areas have been planted on five locations (ecological units), which were selected in order to represent the habitat of the continental region oak woods, the stands belonging to the VII age class (120-140 years). It is the following basic elements of the stand structure that were determined and analyzed, with regard to ecological units: number of trees per hectare, mean diameter, basal area per hectare, mean height, and growing stock. The diameter distributions of the mature oak stands are characterized by a small negative asymmetry. As for the tree crown structure, it was analyzed through tree crown parameters, whereas De Camino’s homogeneity index was used for defining stand homogeneity. In the stands surveyed, the homogeneity is reduced as the habitat conditions deteriorate. By applying the method for determining spatial distribution of trees, significant randomness in tree distribution was stated, with noticeable occurrence of certain level of uniformity of horizontal distribution.
