- The paper assesses the performance of the risk models of the wind damage to the mountain forest stands located in the Tatra National Park (southern Poland). The models assume that the forest susceptibility to the damage from the wind depends on the characteristics of stands, their location and frequency of the occurrence of damage in the past. According to the methodology we built 5 variants of models, which take into account the following attributes: various stand features, forest type, regional factor of the damage to the the trees, thickness scrap, subversive and deadwood from the stand in the last 10 years, characteristics of the terrain: exhibition, slope inclination and altitude above sea level. The model output is a classification of the stand susceptibility to the wind damage expressed by a number between 0 and 3 (0.5 interval). The suitability of each variant was tested by comparing the in−class rate as well as the area and growing stock of undamaged and damaged stands. In this study we rated 2908 stands with a total area of 15,386.05 ha. Taking into account the risk class, it is possible to develop the appropriate procedures in order to limit the damage. The analysis conducted for the forests of the Tatra National Park showed high compliance of the developed risk models with the damages arising by the wind. This is confirmed by a particularly high proportion of damaged forest stands included in the class of high risk. Their fraction ranged from 43.8% (WR1) to 92.4% (WR5). Considering the position and stands characteristics the greatest damage arose at an altitude of 950 to 1000 m (70.2%) and the exposures NW, N and NE (60.2%).
