| Description | Forests in Šumava Mts. (Western-Bohemian Czech-Bavarian border area) were heavily Kyrill has damaged by this wind storm in January 2007. Various geostatistical methods were applied to identify relationships between relevant natural factors and areas with forest damages (predominantly Norway spruce stands). Only low relationships have been identified with site features (e.g. slope, aspect, soil depth and humidity). More important relationships can be seen in results of the integrated area wind storm risk assessment based on the classification of slope, aspect, soil depth, area humidity, canopy age, density and species composition using a ball scale 0-3 marks and feature weights dependently on their impact heterogeneity. Five classes of area sensitivity to forest wind damages were detected and compared with Kyrill consequences. It is clear, that the site and canopy sensitivity to wind storm damages plays only a limited role in the origin and level of damages. The decisive role is played by the wind. It behavior stays under the future research. |
