Alpengartenhaus Patscherkofel

Der Alpengarten der Universität Innsbruck liegt auf einer Höhe von 1.890 bis 1.950 m im Waldgrenzbereich knapp unterhalb des Patscherkofelhauses und in unmittelbarer Nähe zur Bergstation der Patscherkofelbahn. Der Garten erstreckt sich über eine Fläche von circa 2 Hektar die großteils frei zugänglich sind und ein beliebtes Ziel für Besucherinnen und Besucher des Patscherkofels darstellen. Das 1997 errichtete Alpengartenhaus wird durch das Institut für Botanik für Lehre und verschiedenste Forschungsaufgaben genutzt, es ist außerdem die Basis für die Betreuung des Alpengartens durch die Gärtnerinnen und Gärtner des Botanischen Gartens der Universität Innsbruck. Das Haus verfügt über zwei Laborräume, Küche, Schlafräume und Sanitäranlagen sowie Stauraum für Geräte und einen Pumpraum für die hauseigene Quelle. Ein Teil des eingezäunten Grundstücks ist nicht öffentlich zugänglich und daher für Experimente sehr gut geeignet.

Am Patscherkofel werden unter anderem Anpassungsmechanismen und Überlebensstrategien alpiner Pflanzen – vor allem Nadelhölzer – auf extreme Umweltbedingungen wie Kälte und Trockenheit erforscht.
