Alpine garden on Mount Patscherkofel

The alpine garden of the University of Innsbruck is situated on the north-western exposed slope of Mount Patscherkofel at the forest line between 1,890 and 1,950 m a.s.l. The area is about 2 hectares large and contains a research station, a public area and restricted space for scientific experiments. The research station was built in 1997, it is equipped with laboratories, a kitchen, bedrooms, sanitary installations and stowage space.

The station is used for university courses and research on survival mechanisms and adaptation strategies of alpine plants facing extreme conditions like frost and drought.
