Drought in Switzerland is further intensifying. Particularly forest trees in the lowlands (Mittelland) show steadily increasing tree water deficit-induced stem shrinkage (TWD, Baumwasserdefizit). The values are far above the TWDs…

Rain over the weekend brought some stress relief to forest trees in Switzerland, particularly in the Northern Alps and in the Valais (see situation on July 16). In these two…

Trees in the Northern Alps and in the Valais show distinctly higher tree water deficit-induced stem shrinkage (TWD) than in the years before. We conclude that the investigated tree species…
