FURTHER INFORMATION

Projekte

VPDrought: A novel approach to disentangle atmospheric and soil drought

Mit dem Projekt «VPDrought» werden die Einflüsse und Auswirkungen von Luft- und Bodentrockenheit auf den Wald wissenschaftlich untersucht. Der weltweit erstmalige Versuch in dieser Kombination und Qualität wird im Pfynwald auf der bereits bestehenden Forschungsfläche der WSL umgesetzt.

Acclimation and environmental memory

Which are the main mechanisms conveying adaptation on the organ and whole tree level, how fast does acclimation occur and how long is an acclimation potential sustained?

Irrigation Experiment Pfynwald

Drought-induced forest decline will gain in importance as the frequency and severity of drought events are expected to increase in the context of climate change. To understand how chronic drought affects tree growth, we study mature Scots pine in an irrigation experiment in an inner-Alpine dry valley since 2003.

Crown condition assessment

It is important to have good information on the condition of the trees in the plots. Therefore scientists determine the relationships between crown condition and a number of environmental parameters.
