The Tyrolean Lech Nature Park is an extremely species-rich area. It is a reserve for many endangered plants!
After the ice ages, many plant species spread on the gravel areas along the Lech towards the Alps or the Jura. Like no other river landscape in the Northern Alps, the Lech Valley has a central importance as a migration and dispersal line (floral bridge) for the flora between the Alps and the Jura. The Lech serves as a dispersal axis. The seeds of the plants are not only spread by water, but also by wind. This allows them to spread both downstream and upstream. In this way, many plants can establish themselves. But also the close interlocking with the riparian forests contributes decisively to the species richness, as many plants find a suitable habitat as a home here.
Therefore, it is not surprising that the floodplains are called the "jungles of Central Europe". No other type of landscape in Central Europe is as diverse and species-rich! One third (1,116 species) of all plants native to Tyrol grow in the Tyrolean Lech Nature Park. Of these, one third (392 species) are very valuable and classified as endangered and are at home at the Tiroler Lech!
