Forest fire

Forest fires are frequently caused by humans and refer to the uncontrolled burning of scrub, grass or woodland. Forest fires can arise throughout the whole of Switzerland, especially in valleys, where the ‘foehn’ (hot south wind) is prevalent and during extensive periods of drought. Forest fires may impair the functions of the forest (e.g. protection). As a result of the changing climate, the frequency and extent of dry periods will continue to grow in the future, which will also raise the risk of forest fires.

Forest fires can block traffic routes. Danger zones may be closed off. If a forest fire threatens individual houses or neighbourhoods, they may have to be evacuated. Fortunately this happens only very rarely, as Switzerland does not permit houses or neighbourhoods to be built in the woods. Attention must also be given to the indirect consequences of forest fires, such as the loss of protection or ash mudslides that may have an impact on the daily lives of the population. If there is an evacuation, it may take several days or even weeks before you can return to your home.
