Growth characteristics of Austrian pine (Pinus nigra) were researched in the artificially established stand on the site Quercetum–frainetto cerris Rudski. The stand was 53 years old. The characteristic elements of stand growth were mean diameter (dg=24.9 cm), mean height (hL =20.0 m), basal area 43.2 square m, wood volume (V=408 cubic m/ha) and number of trees (N=891/ha). Based on the analysis of diameter structure, diameter increment, crown development and form ratio, it was concluded that the actual stand state did not enable the appropriate stand development and the conservation of its stability. For this reason, the Model of optimal stand state was designed, based on the optimal crown cover area. Optimal crown cover area is the crown cover area which ensures the maximal basal area of the stand. Based on this Model, the stand should have 661 trees per hectare, mean diameter 28.3 cm, basal area 40.2 square m and volume 400 cubic m per hectare. Also, a considerably larger mean diameter (28.3 cm) is achieved, as well as the conditions for the greater stand stability and quality.
