The restoration project on Læsø Trindel is yielding results! This is the edifying message from The Danish Agency for Spatial and Environmental Planning, the responsible institution. “Observations made by an underwater camera show shoals of fish, crabs and algae”, says Mrs. Else Marie Stamphøj from the agency, and adds: “This is certainly a successful outcome.”

Læsø Trindel just 12 km north-east of the Danish island of Læsø used to be a large cavernous boulder reef formed during the ice-age.

Over the years the reef has gradually vanished as the easy to get at boulders have been excavated for constructional purposes, leaving a much depleted reef. This has severely impaired the habitat.

Shallow water boulder reefs have a high biodiversity and are important habitats for a wide range of species. BlueReef is the first large marine nature restoration project in Denmark and is expected to provide a wealth of knowledge on how marine habitats can be improved.
