The reserve was created in 1997. The purpose of its classification is to protect one of the last strips of alluvial forest, which is rare and in regression everywhere in Europe. The City of Strasbourg is its managing authority.

Definition of a nature reserve

Nature Reserves are spaces that host fauna, flora and habitats, but also fossils of special importance, which it is our duty to protect. They are extraordinary places with their own history.

Nature Reserves vary in size, the smallest being the Saint Nicolas des Glénan Reserve (1.5 hectares) and the largest the Nouragues Reserve (100,000 hectares, French Guiana).

The protected habitats are various: they may be lakes, marshes, peat bogs, rivers, forests, meadows, etc.

History of the creation of the Rohrschollen Island Nature Reserve

In 1965, scientists and clubs, as well as local residents, were concerned for the future of the alluvial forests in Alsace. Indeed, these areas were suffering from river canalisation works and their surface areas were being gradually eaten away. These special ecosystems were what remained of the Rhine forests as they stood before the first development works began on the Rhine. Humid areas of this kind are particularly interesting from an ecological point of view owing to their rarity, their biodiversity and their specific treasures. It was therefore necessary to protect this heritage and classification as a Nature Reserve was the consequence of this realisation.

In 1977, Strasbourg Municipal Council asked the Prefect to apply the law of 10 July 1976 on nature protection on Rohrschollen Island. Classification proper occurred 20 years later, by Ministerial Decree, enacted on 4 March 1997 (download the Decree). The Prefect of Bas-Rhin appointed the City of Strasbourg as managing authority of the reserve. The City went on to recruit a team to join its Green Spaces and Nature Department to handle this mission.

A consultative committee chaired by the Prefect represents all of the partners (local authorities, landowners, public authorities, public bodies, scientists and nature protection clubs) and is responsible for taking decisions and administration of the site.

For the studies undertaken in the nature reserve, a scientific committee meets regularly to check the relevance of the protocols (download the Order establishing the composition of the CSRPN – Regional Scientific Natural Heritage Committee).
