Abstract

The area of investigation comprises the central part of the North Tyrolean Limestone Alps, north and south of the German-Austrian border. Historical archives are analysed to determine the frequency of historical wildfires, as well as mapping vegetation regeneration on 20 slopes of different post-fire ages, and soil erosion measurements on 2 slopes. It is highlighted that vegetation regeneration takes an extremely long time under unfavourable conditions and that soil erosion constantly increases in the years after the fires. A two-part vegetation regeneration model is proposed depending upon the degree of soil loss. It is observed that after severe soil destruction the slopes may remain degraded for a century or longer, before rather rapid regeneration occurs. The reasons are not fully understood but are probably governed by geomorphic process intensity
