It has reconnected two old meanders and widened the River Enns, whilst also se- curing and regenerating the natural alluvial forests. This is to the benefit not only of Mother Nature but also of people living in the Enns valley. “River Landscape Enns” constitutes an impressive example of just how possible it is to reconcile differing objectives. The project improves local people’s safety and creates more space for nature and recreation. The river is undergoing ecological improvement in accordance with the EU Water Framework Directive whilst, at the same time, flood protection for local people is strengthened. Cooperation between the local project partners, the organisations respon- sible for the project and the participating municipalities enables the creation of attractive natural and recreational areas. Additi- onally, the implemented measures provide an important contribution to the conservation of habitats and species protected under European law. We offer our heartfelt thanks to everyone who has contributed to the success of the project and wish you all necessary strength for the tasks ahead.

Description of the area | 07 The history of the River Enns The shape of the Enns valley as we see it today arose as a result of the erosive power of the last Enns glacier. A flat river basin emerged, and the Enns became a meandering river with numerous loops. Originally the River Enns flo- ruction measures and the se- wed from one side of the val- dimentary material was held ley to the other.
