Research Station Praxmar

The research station Praxmar is situated in the Sellrain valley at an elevation of 1,667 m a.s.l in a forest of spruce and stone pine. The facility is a chalet previously owned by the federal forestry service of Tyrol but has been used by scientists of the University of Innsbruck for botanical and ecophysiological research for about 20 years. The chalet was acquired by the university in 2019 and is currently under conversion to cope with latest research demands. The chalet is within easy reach by car and a road leads up to the tree line region.

Current research projects address questions on hydraulic performance of tissues of wooden alpine plants under severe weather conditions as well as on rust fungus infections of spruce trees.
