Tree water deficit (TWD) The extremely dry summer 2018 left clear effects in forest trees. Trees at about 25 of the 30 measured TreeNet-sites showed record-high values of TWD exceeding…

La mise au point: La canicule tue nos forest? TreeNet contributes scientific information about the damages induced by the drought summer 2018

Etzold, S.; Zweifel, R., 2018: TreeNet – Daten und Analysen der ersten fünf Messjahre. Mit Beiträgen von: Haeni, M.; Burri, S.; Braun, S.; Walthert, L.; Dawes, M.; Buchmann, N.; Haeler,…

Rain over the weekend reduced the tree water deficit (TWD) in most trees of all species. However, we are far from an average situation. Most trees are still showing TWDs…

3Sat – nano Bäume leiden unter akutem Wassermangel Die Wissenschaftssendung nano synchronisiert den SRF Beitrag ins Deutsche. 15.8.2018 SRF – Schweiz aktuell Bäume leiden unter akutem Wassermangel Wegen der Trockenheit…

Drought intensity reaches a new (last?) peak in this summer. Forest trees of all regions investigated are heavily affected according to our drought-indicator TWD (tree water deficit). The values are…

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…
