Abstract
On the occasion of the International Mountain Day (11 December), the Alpine Association South Tyrol (AVS), together with the Center for Global Mountain Safeguard Research (GLOMOS) and the Biodiversity Monitoring team of Eurac Research, draws attention to the special importance of mountain ecosystems for biodiversity. The South Tyrolean mountains are home to unique animal, plant and fungal species, which is why it is particularly important to treat the mountain region with care.
