Successful renaturation of the Dreisam: Fish population explodes!

Successful renaturation of the Dreisam: Fish population explodes!

Nimburg, Deutschland - The renaturation of a section of the Dreisam near Nimburg, in the district of Emmendingen, has now been completed. With a budget of around 30,000 euros, an approximately 700 meter long section of the river was redesigned. The aim of these measures is to improve the habitat for fish and other water creatures, which should also increase local biodiversity. This initiative ensures that cold groundwater seeps into the river bed with temperatures around 12 degrees, which is a survival condition for many species. Excavators created several fish pools with a depth of up to 1.60 meters, which offer a lifelike place even at low water levels.

To ensure flood protection, protective walls were also built from V-shaped tree trunks. These tree trunks ensure water displacement and increase the oxygen content in the water, which is vital for the aquatic ecosystem. In addition, the large root plant of the trees ensures shade and protects the fish from predators. Before and after the renaturation, experts examined the fish stocks: the population has more than doubled from around 1,100 to over 2,500 fish, while the number of types has grown from 11 to 14. Bernd Walser, the river champion of the Freiburg regional council, emphasized that this project was a real success. He hopes that the experiences gained as a blueprint for similar projects on other rivers can be used, so SWR.

background of the renaturation

The renaturation of the Dreisam is part of a larger initiative that aims to revitalize the life rooms in Germany. Although the term "renaturation" is used, in many cases it is more correct to speak of "revitalizations". A complete return of the Dreisam to its original state is not possible due to the strong construction. Instead, the measures carried out aim to design the rivers in natural seamies. These projects are not only important for the flora and fauna, but also contribute to reducing flooding and increasing the quality of life in the city and country, as can be seen at the Federal Environment Agency

The Dreisam interest group emphasizes that the cooperation of numerous organizations as well as municipal and state departments is necessary in order to successfully implement such projects. It is important to protect ecological rivers from harmful human interventions. The spectrum of possible measures ranges from the elimination of hard bank fortifications to the re -connection of alarms so that the waters can regenerate themselves. One goal is that the life of water can take on an even stronger ecological function and can withstand the challenges of climate change better.

outlook and meaning

The success of the renaturation at the Dreisam could go to school. Projects like this are crucial to protect nature and promote biodiversity. In times of climate change, the creation of nature -related habitats becomes a central task - both for the environment and for the people who outgrow in their living environment. The knowledge gained should help to implement similar measures sustainably and thus also have a good knack in the country in the country.

For people who are interested in sustainable planning and implementation, the online platform "Renaturation of flow waters" offers valuable information and support. Intact rivers are more than just watercourses-they are habitats that are important for humans and the environment, such as ig Dreisam.
