In the course of this paper four forest districts of the Österreichische Bundesforste AG (Austrian Federal Forests) were examined concerning costs incurred over the past 40 years caused by browsing and fraying damage. Goal of this paper was to obtain operation figures of the segregation costs caused by game damage on district level as well as for the surface areas of the first age class. The calculation of the segregation costs was effected by a target-actual comparison of the forest stand target for the current age classes I and II. This was calculated separately for every forest stand target altitude zone. The results are stated in Euro per hectare and year, separately for the first and second age class and as average costs of the first and second age class. Since the forest districts are not always composed of the same bedrock, subareas with the homogeneous bedrock were analysed in every district. These were two subareas of limestone, one of silicate and one of flysch. The reason for this is to receive a comparison of the segregation costs depending on the bedrock. For every rock type there are different forest stand targets with varied tree species composition and tree species distribution. The varied tree species composition and tree species distribution affect in turn the amount of the segregation costs. The investigation areas (forest districts respectively subareas) have different age class distributions and thereby a varied amount of game damage vulnerability. In order to compare segregation costs the forest districts and subareas with each other, a normal forest scale model was calculated for every investigation area with the same age class. The results of this paper should provide support for business-related questions concerning silvicultural and game managerial issues and calculations.
