The compiled information on river restoration success factors provides input to the development of pan-Baltic recommendations and guidelines for river restoration and management of sea trout rivers and stocks. RETROUT will evaluate already completed restoration projects in order to identify what methods gives the best results. The working group includes experts in the fields of river restoration, fish biology, cultural history, water resources management and environmental communication.
As the project spans a large region, with similar problems and focus species, the joint learning from previous and on-going restoration projects constitutes an important basis for improving and facilitating future projects. The compiled information on river restoration success factors will support national, regional and local administrations to identify the most cost-efficient measures of improving water quality and fish stock status such as the management of coastal and marine resources to underpin sustainable blue growth sectors.
Within the RETROUT project, fifteen river restoration demonstration cases are being conducted to restore sea trout populations in coastal rivers in Estonia, Lithuania, Latvia, Poland and Sweden. Measures include fishways, biotope restorations, water quality improvement, and dam removal plans. These restoration activities are carefully documented and will serve as a basis for developing river restoration guidelines for the Baltic sea region, to be used by local, regional, national public authorities. The main objective is to provide a list of best available practices and recommendations for cost-efficient and effective river restoration for enhancing ecological quality and increasing sea trout productivity.
