In a joint research project with Ukrainian partners we compare the structures of the virgin beech forest Uholka in Ukraine with those of the Sihlwald near Zurich and assess the development process of Sihlwald from commercial forest back to "virgin forest".

The chemistry of soil solution and the soil water availability for plants have been monitored since 1997 in seven forest plots in Switzerland. This project, linked to the Swiss Long-term Forest Ecosystem Research project (LWF), aims to assess the soil response to atmospheric pollution (acidifying substances and nitrogen) and to climate change.

Microclimate, fluxes of CO2 and other gases by eddy covariance and tree physiological measurements under field conditions have been recorded at the Seehornwald Davos research site for two decades. Currently, we are analyzing the unique data sets in terms of tree physiological responses to climate change over the recent decades.

In Valais, Scots pine (Pinus sylvestris) and pubescent oak (Quercus pubescent) grow at least temporally at the edge of their physiological capabilites. We investigate the (potential) adaptation of these and co-occurring tree species to climate change and search for limits they might reach with increasing temperatures and droughts.

Within the frame work of the UNECE Convention on Long-Range Transboundary Air Pollution, the WSL investigates the physiological and growth effects on trees by means of ozone flux modeling in order to assess the risk of ozone on forest ecosytems.

Querco, in the sense of "quid Quercus, quo vadis?" To study the reaction of 3 local species of oak (each species with 4 provenances) to drought, increasing air temperature and a combination of the two will be the focus of this experiment.

Aktuelle und historische Waldschutzdaten bilden die Grundlage für die laufende Beurteilung der Waldschutz-Situation sowie für Prognosen und Risikoabschätzungen von abiotischen und biotischen Einflüssen auf den Wald. Die Daten werden mit verschiedenen Methoden beschafft und laufend ausgewertet.

Insekten prägen massgebend die Dynamik unserer Waldökosysteme, z.B. durch Massenvermehrungen. Informationen zur Verbreitung, Biologie und Epidemiologie der Waldinsekten dienen dazu, angepasste Massnahmen der Überwachung und Bekämpfung zu erarbeiten. Praxis und Behörden stützen sich bei ihrem Risikomanagement auf unsere wissenschaftliche Beratung und Diagnose.
