This report documents the project work and results of the R&D project "Information Platform for the restoration of rivers", which was jointly carried out by Ecologic Institute, Planungsbüro Zumbroich and the Institute of Aquatic Ecology and Fish Biology, Jena (IGF Jena) from 2017 to 2020. The aim of the project was to create an online information platform about river restoration (Part I of the project report) and the analysis of German restoration projects in regard to their monitoring (Part II of the project report). The report is available for download.
This brochure provides insights into the contents of the Federal Environment Agency's online information platform "River restoration". The aim of the platform and this brochure is to motivate and support potential actors for increased implementation of river restoration measures. Therefore, basic knowledge on the ecological development of rivers and brooks is provided in a clear and understandable way. It also provides information on practical issues of planning, financing and land provision, but also on flood protection, nature conservation, agriculture and recreation. Restoration project examples further illustrate these topics. The brochure is available for download.
This article introduces the German Federal Environment Agency's online information platform on river restoration. It was designed, compiled and implemented between 2017 and 2020 by Ecologic Institute, Planungsbüro Zumbroich and IGF Jena. The information platform provides basic knowledge on the restoration of rivers and serves to gain acceptance for restoration measures. It addresses towns and municipalities, water management authorities, water bodies associations, fishing associations and citizens' groups.
This information platform provides information for potential actors of renaturation projects. The aim of river restoration is to return rivers and streams to their natural state and to improve their ecological status.
The water landscape of the Hase and its tributaries Lower Saxony is ecologically upgraded. The dykes are relocated, floodplain revitalisations and watercourse conversions are carried out. This can only be done in close cooperation with all those involved, but above all with agriculture, which makes land available and extensifies uses.
More than 20 individual measures were implemented to ensure the continuity and restoration of the Ruhr in Arnsberg. This resulted in a near-natural river landscape in the middle of the city. The restored Ruhr is increasingly shaping the cityscape. Flood protection has also improved significantly.
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.
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.
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.
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.
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.
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.
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.
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.
