The riparian forest

What is a riparian forest? Definition:

As Auwald Vegetation zones are designated along rivers and streams, which are subject to a frequent change of high and low water. Often these biotopes are also under the synonymous term Auenwald known. The word "Aue" originally comes from the Old German and means something like "land on the water". Depending on the state of flooding, the season and the speed of the river, the vegetative appearance of the forest can vary greatly.
Rural meadows make special demands on the fauna, because the plants not only have to cope with the changing conditions (permanent wetlands and longer dry periods), but also have a stable root system, so as not to be washed away at high tide. In particular, ash, alder, elm and willow are often found in alluvial forests. On the one hand, these robust trees tolerate temporary amazements and on the other hand they have a deep, stabilizing root system.
A large part of the natural floodplains in Germany have already disappeared, due to man-made river strains. In the meantime, by restoration (restoration of natural conditions) at least in sections along rivers or streams, attempts are being made to favor the emergence of alluvial forests. Alluvial forests are among the most species-rich ecosystems because of their frequently changing environmental conditions.
The flooding in recent decades brought many communities in Germany to rethink. Renaturation of the rivers (including the concession of large open spaces) allows the immense amounts of water to escape, causing flooding in inhabited areas to be much rarer. For instead of crossing the rivers in the cities, the water is scattered on the open spaces outside the cities, creating a habitat for fish, birds, amphibians and smaller mammals.
