Find all of the actions planned on the nature reserve as part of the Rohrschollen Island Life+ Project here.

The project includes a total of 22 actions, grouped by category according to the coding of Life+ projects

Preparatory actions

Eight studies are planned in the context of the project. The first ones began in autumn 2010 and continued in 2011 through 2012. They concern the definition of works and their implementation, hydraulic modelling of the effects of planned developments, the compilation of the regulatory dossiers needed to carry out the works, mapping of current status and the drafting of a scientific monitoring protocol on actions intended to restore dynamic flooding.


Concrete conservation actions

These actions concern the construction and completion of works, which have begun by the end of 2012.

In order to re-establish dynamic flooding conditions on the island, the various components of the works scheduled are the following:

  • Water diversion structure on the Rhine upstream of the Strasbourg diversion dam to be used to control a variable flow rate according to hydrological conditions.
  • Crossing structure over the dam road and headrace canal, enabling transit of the maximum flow rate injected without causing overflow on the first 250 metres of the course, in order not to erode the foot of the diversion canal dyke and the feet of the electricity pylons.
  • Connection channel to the Bauerngrundwasser, establishing the link between the headrace canal and the Bauerngrundwasser. Its specifications will be as close as possible to the natural arms of the Rhine: variable cross section profile with pools and riffle areas, development of spawning areas, connection to the surrounding depressions…

Public awareness and publication of the results

In the context of the project, there are plans to produce: a trilingual internet site to track and present the results, informative leaflets, display panels, educational outings, work with the media, a seminar to exchange views on issues regarding the restoration of the alluvial habitats of the great rivers and a layman's report at the end of the project.

Project monitoring

Monitoring and a scientific assessment of the impact of project are planned, as is the networking of information with other projects.
