In the 1990s four storms in the Alpine regions caused quite a stir: in February 1990 Vivian and Wiebke, and in December 1999 Lothar and Martin. What they all had in common was the devastation they caused; what was also remarkable was the short time span between them. The Dossier's background report, which is available only in German, outlines the extent and causes of the damage caused in the forest areas and the way in which the storm areas were addressed depending on the different interests governing the use of those areas.
