Isar renaturation: Nature experience near Ettling inspires over 60 participants!

On Wednesday there was an exciting evening excursion to the renaturation of the Isar near Ettling, organized by the Landau Nature Conservation Association. Over 60 nature and environmentalists, many of whom arrived by bicycle, gathered at the sports field to find out more about the valuable ecological measures. Excursion leader forester Tobias Schropp from AELF Landau Pfarrkirchen led the group through the fascinating landscapes that unfold along the river.

Mayor Franz Aster opened the event, which was also supported by BN board member Franz Meindl. An important topic of the excursion was the historical course of the Isar. Historical maps from 1850 document the original course of the river, which was rich in tributaries and backwaters. In the 20th century, however, the Isar was straightened and reinforced with concrete, which reduced the dangers of flooding but also had negative consequences for the ecosystem. The river now has little power to shape itself, which is why changes now usually have to be brought about by machines.

Renaturation brings back diversity

During a tour of the new steep banks and gravel islands, the participants were able to admire the first results of the renaturation measures. These extend over around four hectares and were deliberately created without paved footpaths and cycle paths in order to give priority to nature. Forester Schropp introduced the group to the remarkable birdlife that has settled in the renovated area, including kingfishers, goosanders and greylag geese. With a bit of luck, some of the participants were also able to spot herons, ducks and even ringed plovers.

Another highlight was the visit to a bridge on the right side of the Isar, where forester Schropp explained the characteristic vegetation of the renaturation area. The experts expect that a softwood meadow with willows, poplars and other tree species will emerge here in the coming years. The old pollard willows are particularly valuable, as they provide a habitat for more than 50 species of rare beetles, including the endangered hermits.

Sustainability in focus

The renaturation of the Isar is not only a sign of the return of habitat for flora and fauna, but also part of larger programs to improve water quality in Germany. As part of the EU Water Framework Directive and the federal “Blue Ribbon” program, numerous projects aim to improve the ecological status of water bodies and thus also ensure flood safety. Such measures are of great importance in a broader context, where it is shown that semi-natural water habitats have a positive influence on biodiversity.

The excursion ended at the Holunderhof in Westerndorf, where the participants ended the evening with good food and interesting conversations. The event demonstrated the importance of collaboration between citizens, conservation groups and the community to bring back nature and create a balance between use and protection of the environment.
