Why a Life+ project devoted to Rohrschollen Island? These pages describe the context of which it is part, its objectives, which habitats and species are concerned by the project and what results are expected.

Of the many ecosystems found in the great alluvial plains of Europe, the richest and most complex are the gallery forests. They form long corridors stretching along the banks of the rivers flowing from the Alps, occupying land that is regularly flooded. Their virgin forest-like appearance is due to the exceptional wealth of ligneous species (trees, shrubs, large creepers)

These forests are now regressing as a result of the major works that have been carried out in recent decades to domesticate these rivers. Consequently, the four major European rivers flowing down from the Alps (the Rhine, Rhone, Danube and Po) have lost most of their riparian forests.

Project objectives

This project aims to re-establish a dynamic flood regime on Rohrschollen island, based on the hydrological rhythm of the Rhine.

Habitats and species targeted by the project, expected results

By restoring this key habitat, the project aims also to encourage species that are listed in Annexes I and II of the Habitats and of the Birds Directive. These include the Peregrine falcon (Falco peregrinus), the Great egret (Egretta alba), the Great crested newt (Triturus cristatus) and the Spined loach (Cobitis taenia), which is scarce in the Rhine-Ried-Bruch alluvial sector of the Bas-Rhin département.
