BLUEREEF - Rebuilding of Marine Cavernous Boulder Reefs in Kattegat

In Denmark, cavernous boulder reefs in shallow waters habitats have been extensively exploited –targeted for their high concentration of easy-to-excavate large boulders suitable for constructing sea defences and harbour jetties. The main project objective is to restore and maintain a favourable conservation status of the reef offshore habitat at Læsø Trindel and Tønneberg Banke in the Kattegat bay in Denmark, through restoration of the structure and function of the cavernous element of the shallow offshore boulder reefs and by stabilisation of the top of the existing boulder reef. The project includes a longer period of monitoring of the restored boulder reef. The restored is a significant contribution to maintaining reef-dependent populations in Denmark. The project also increased awareness among environmental managers, policymakers and the broader public on marine nature restoration, conservation and management issues.
