The Dwarf bellflower (Campanula cochleariifolia), which White silverroot (Dryas octopetala), which Alpine edelweiss (Leontopodium nivale), which Alpine elecampane (Linaria alpina) or the Blue-green saxifrage (Saxifraga caesia) would be more likely to be found on the mountain peaks than in the Lech valley. But here they also bloom in the riparian forests and on the gravel banks.

As the snow melts or through mudflows, their seeds are washed down to the Lech and find similar climatic conditions to those at the summit of the Allgäu and Lechtal Alps. Cold in winter, hot, dry and windy in summer, with high UV reflection from the light-coloured gravel - this can also be the climate on the gravel banks and in the pine forests on the Lech. "Alpine alluvials" on the Lech - the visitors from the mountains have rightly earned their name.
