What kind of pests do North-American trees in Europe encounter?

We will explore what pests attack North-American trees in Europe, to inform an early-warning system and blacklists in the USA.

Stand- und Bruchsicherheit von Eschen mit Eschentriebsterben und Hallimasch

Viele Eschen in der Schweiz sind vom Eschentriebsterben betroffen und zeigen Kronenschäden. Wir untersuchen, wie das Eschentriebsterben und sekundärer Hallimaschbefall die Stand- und Bruchsicherheit von Eschen beeinflussen, damit Risikobäume gezielter identifiziert und gefällt werden können.

Effects of bark beetle resource pulses on woodpecker populations

The project aims to assess how the abundance of spruce bark beetles affects populations of woodpeckers. Long-term datasets on the annual amount of spruce timber infested by bark beetles and woodpecker abundance data, along with environmental variables are being used to model these relationships.

Patterns and processes of biological invasions in freshwater and terrestrial ecosystems

Insects are among the most successful invasive species but there are surprisingly few aquatic insects that invaded freshwater ecosystems. In this collaborative project between WSL and Eawag we are analysing several international datasets to determine why insects are under-represented among aquatic i

RESISTASH: Resistance mechanisms of ash to Ash dieback and the emerald ash borer

Switzerland’s ash trees are currently decimated by an invasive fungal pathogen causing the “Ash dieback” (ADB) disease. In addition, the emerald ash borer (EAB) might reach Switzerland in the near future. The joint project between WSL and IAP aims to establish a nation-wide ash monitoring that informs on the spread of ADB in Switzerland and to identify potential chemical resistance mechanisms against ADB.

Drought & beech: Effects of the 2018 summer drought on beech on the northern side of the Alps

In this project, we investigate causes for the impacts of the extreme summer drought 2018 on the vitality of beech trees in different regions of the Swiss Plateau and Jura.

DEFENDASH

Ash is currently suffering from Ash dieback ADB and a new threat, the Emerald Ash Borer EAB, is spreading towards Central Europe. The project aims at understanding the milti-trophic interactions between different ash genotypes, ADB, EAB and its natural enemies under different climatic conditions.

Ash Dieback in Switzerland

In Europe, the Ash Dieback disease caused by Hymenoscyphus fraxineus has led to high mortality rates of common ash. We analyze how radial growth and wood anatomical parameters influence the disease progression in trees.

Tolerant ashes are examined

Tolerant ashes reported in Switzerland are measured and assessed by specialists.

chestnut blight

The introduced chestnut blight fungus Cryphonectria parasitica causes severe damage to chestnut forests and orchards across Europe. We investigate the biology and epidemiology of the disease and provide the scientific basis for biological control.

Kastanienrindenkrebs

Der eingeschleppte Kastanienrindenkrebs gefährdet die Edelkastanienbestände auf der Alpennordseite. Um diese Bestände zu erhalten, wird im Rahmen dieses Projektes der Kastanienrindenkrebs auf der Alpennordseite mit hypovirulenten Pilzstämmen bekämpft

Diagnose von Wald- und Baumkrankheiten

Wichtige Informationen zur Beurteilung der Waldgesundheit stammen aus der Beratung, bei welcher mittels differenzialdiagnostischen Methoden die Ursachen von Baumkrankheiten analysiert werden. Die Kunden agieren als externe Mitarbeiter und erhalten als Gegenleistung die Diagnose inklusive einer Empfehlung für das geeignete weitere Vorgehen.

Schadenanalysen in Forstentomologie

Insekten prägen massgebend die Dynamik unserer Waldökosysteme. Informationen zur Verbreitung, Biologie und Epidemiologie der Waldinsekten dienen dazu, für Praxis und Behörden angepasste Massnahmen der Überwachung und Bekämpfung zu erarbeiten.
