Ecological Restoration of Ski-Runs

Bernhard Krautzer, Wilhelm Graiss and Brigitte Klug

Abstract

The basic principles for long-term ecological restoration of ski-runs are presented. </p><p> Several thousands of hectares every year require restoration in the sub-alpine and alpine vegetation belt of the European Alps. The majority of these areas are used as ski-runs during winter and for agriculture in summer. </p><p> Control of erosion and its after effects, like increased surface drainage and dislocation of soil, is one of the most essential tasks when restoring ski-runs at high elevations. Ecological restoration of such areas requires the combination of high quality application techniques and site-specific seed or plant material containing species adapted to the given site conditions. Average slope inclinations of 30% to 45% in the vicinity of skiruns require the additional use of mulch covers to avoid increased surface drainage and noticeable soil losses during the first two vegetation periods. In the long-term, sufficient protection against erosion can only be guaranteed if stable, enduring and ecologically adapted sub-alpine and alpine plant species become established.
