South Tyrol is a mountainous country. A considerable part of the land area is above 2000m a.s.l. The conditions are extreme, making tree growth no longer possible above a certain altitude. Soil formation is also very slow. This makes the substrate all the more important: whether the soil is limestone or silicate, results in completely different vegetation. This, in turn, results in very different communities of insects and other small animals. In total, we investigate 60 alpine areas at an altitude of 2300 to 3000m above sea level in biodiversity monitoring. We have assigned the areas to two major categories: Areas with a closed meadow layer and more extreme areas dominated by rock, scree and open soil.
