Systematische Gewässerentwicklung an der Wern

Systematic river development on the Wern

The river Wern in Franconia was modified in the 1930s in order to enable agriculture right up to the edge of the river. As a result, biotope and species diversity declined significantly. Since 1995, the Wern has been gradually regaining a near-natural state through systematic, sectional restoration measures.Read more

Flächenmanagement und Gewässeraufwertung an der Nebel

Land Management and River Restoration at the River Nebel

Long-term land management enabled extensive restoration of the river Nebel in Mecklenburg. In the lowland areas, construction measures were necessary because there is not enough flow velocity for a self-dynamic development. Restoration also increased ecosystem services such as carbon storage and landscape cooling.Read more

Renaturierung und technischer Hochwasserschutz an der Helme

Restoration and Technical Flood Protection at the River Helme

An innovative approach combines technical flood protection and restoration of the river Helme near Sundhausen in Thuringia. The risk of flooding is significantly reduced and companies are settling in the now flood-free industrial areas. Rare and protected species, such as the endangered river mussel (Unio crassus), also benefit from near-natural flood protection measures.Read more

Barrierefreiheit und Lebensraum für Fische an der Ahr

Continuity and Habitats for the River Ahr's fish

Fish can again reach reproduction areas in the upper Ahr without any obstacles. In addition, the Ahr estuary was restored and almost 100 obstacles to fish migration were rebuilt or removed over a distance of 62 km up to the Eifel region. Cooperation between water management, nature conservation and fishing enabled the creation of this habitat network.Read more

Renaturierung des Inn in Kooperation von Wasserkraftunternehmen, Freistaat und Fischereivereinen

Restoration Measures at the River Inn in Cooperation with Hydropower, the Free State of Bavaria and Fishing Associations

Technical flood protection and the use of hydropower have heavily modified the river Inn. Fish hardly find their vital habitats here. The local hydropower company restructures the river banks, creates alternative habitats and promotes biodiversity in the floodplain. The measures are implemented in close cooperation with the Free State of Bavaria and local authorities and interest groups.Read more

Verbesserung der Gewässerökologie an der Murg in Rastatt

Improving Water Ecology of the River Murg in Rastatt

In the urban area of Rastatt, river bank protection of the Murg was removed in order to create near-natural hydromorphological structures. Out of town, floodplains were reactivated for flood protection. The Yellow-bellied Toad and the Crested Newt also benefit from the restoration measures.Read more

Naturnaher Hochwasserschutz an der Fulda

Natural Flood Protection on the Fulda River

The "Masterplan Fuldaaue" is an example of good cooperation between the Hessian municipalities of Bebra, Rotenburg and Alheim. The Fulda was restored near-naturally and flood protection was improved. Financing was provided by different funding sources and the costs were kept low by creative solutions.Read more

Rückkehr von Fischotter, Lachs und Tüpfelsumpfhuhn an der Wümme

Return of Otter, Salmon and Spotted Crake at the Wümme

Today, Fischerhude's floodplain of the Wümme near Bremen is an area of recognised ecological importance, especially for waterbound breeding and resting birds. This was made possible by a large-scale nature conservation project, in which numerous measures have been carried out since 1992 to restore water bodies, including the relocation of dykes, the creation of spawning grounds and riparian buffer strips.Read more
