ExpeER (Experimentation in Ecosystem Research) is a European project (2010-2014) which aims to bring together, for the first time, the major observational, experimental, analytical and modeling facilities in ecosystem science in Europe. By uniting these highly instrumented ecosystem research facilities under the same umbrella and with a common vision, ExpeER intends to form a key contribution for structuring the very fragmented research community on terrestrial ecosystems within the European Research Area and improving the quality and the performance of these infrastructure components in a durable and sustainable manner.

It is tested experimentally if autochthonous Scots Pine (Pinus sylvestris) can adapt to future climatic conditions at the Central Alpine forest-steppe ecotone, or whether tree regeneration might be assured by facilitating the migration of more drought resistant provenances and species, e.g. from southern Europe.

The toxic effects of tropospheric ozone concentrations on the natural vegetation have been reported primarily for ecosystems from the northern hemisphere with a mediterranean, temperate or boreal climate. In the southern hemisphere with its tropical climate, the impact of ozone on natural ecosystems is still unknown.

With a quickly growing world population and raising demand for agricultural products, the productivity of irrigated agricultural soils is threatened as a consequence of soil salinization in many places with arid climates. Main objectives of this research project are to investigate the compartmentation-based mechanisms contributing to tolerance in foliage of poplar trees grown on soils contaminated with elevated levels of Boron and salts in the San Joaquin Valley in Central California.

Das im QUERCO-Experiment der WSL erworbene Forschungswissen über das Verhalten von Eichen im Umweltwandel wird für die Praxis (Forst und Naturschutz) aufgearbeitet und zielgruppengerecht kommuniziert. Dabei soll auch das Verständnis und die Zusammenarbeit zwischen Forschung und Praxis weiter verbessert werden. Zudem wird auch eine breite Öffentlichkeit informiert.

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.

Ziel dieses Dienstleistungsprojektes ist die Erhöhung der Vertrauenswürdigkeit aller LWF-Meteodaten von 1997-2011 mittels einer zentralen, einheitlichen Qualitätsprüfung und Bereinigung mit den Methoden, wie sie MeteoSchweiz verwendet. Auch soll die Datenzugänglichkeit erleichtert und damit der Aufwand zur Bearbeitung von Datenanfragen reduziert werden.
