Dry forests raise risk of falling branches in Switzerland

Swiss broadcaster SRF reports that extreme heat and a lack of rain have severely weakened forests across Switzerland, increasing the risk of branches and entire sections of tree crowns falling without warning.

Forest association Wald Schweiz advises visitors to stay on official forest paths and roads, follow local information and check conditions with the local forestry service. Some particularly dangerous sections have been closed for safety reasons, and visitors are urged to observe those bans.

Follow forestry instructions

Visitors should follow all instructions from forestry services, Wald Schweiz director Christoph Niederberger said. The guidance applies both to the dangers caused by extreme drought and to the logging season, which has already begun in many places.

People should remain on paths, respect nature and follow information from forestry authorities and forestry companies.

Beech trees show signs of stress

The effects of the drought are especially visible in beech trees. Their crowns are often completely dry, while their leaves and bark have turned brown. In windy conditions, branches and entire crown sections may break off. The same applies to individual dead branches.

Wald Schweiz recommends leaving detailed assessments to forestry specialists. Visitors should remain particularly alert and avoid forests altogether when winds become stronger.

Jura foothills among the worst affected

The exceptional situation affects all regions of Switzerland and every elevation, following the extreme summer heat of 2026. Wald Schweiz identifies the southern foothills of the Jura as one of the hardest-hit areas. Prolonged drought and the region’s barren limestone soils have further worsened the already critical condition of the trees.

Rain and cold needed

Wald Schweiz says there is considerable uncertainty about how the situation will develop in the near future. Current measures are focused on protecting forestry workers and the public.

The association is also concerned about a possible severe outbreak of bark beetles, which could lead to extensive compulsory felling. Only substantial rainfall can relieve the dried-out soils, while a cold winter would be needed to limit the spread of the beetles. Forestry services are closely monitoring conditions and will take the necessary steps at the appropriate time.
