This thesis deals with the optimization of the target thickness in the forest managed under systems involving coupes, when converting to a permanent forest (not managed under systems involving coupes) on ŠLP ML Křtiny. The optimization was focused on Scots pine, European beech, Oak sessile and Norway spruce tree species. The final optimal target thickness was established as the intersection of biometric and economic aspects for pine 45 cm (range 39-52 cm), for beech 50 cm (range 44-56 cm) and for spruce 52 cm (range 48-58 cm). In the case of oak in the natural conditions, the culmination of the thickness growth is not occurred. That could reach dimensions of trees, they need, in addition to the appropriate site conditions ensure appropriate production measures the optimal cenotic position, respectively a growth area. The average social area is for oak 26.22 m2, for pine 29.08 m2, for beech 25.26 m2 and for spruce 22.88 m2. The average available crown space is for oak 27.83 m2, for pine 26.59 m2, for beech 23.64 m2 and for spruce 19.38 m2. The average available stem space is around 74 m2 for oak, 84 m2 for pine, 71 m2 for beech and 66 m2 for spruce. Since it is an exact determination of the culmination of the thickness growth using growth ring analysis is time consuming, is better a simpler (operational) the landscaping solutions in adult stands, trip during which evaluates production potential habitats and species on the basis of the achievements of the individual dimensions of the strongest individuals in a selected population. This information is suitable ideally complement the statistical data from the operational inventory, and it must modify their best as the upper quartile breast height diameter of the wood.
