The Halligen of Oland and Langeneß, connected to the mainland by a dam, are of fundamental importance for ground-nesting coastal bird species in the Wadden Sea World Heritage Site.
Since the dam was heightened, increased sedimentation and vegetation growth have made it easier for foxes and raccoon dogs to cross over to the Halligen. This threatens colonies of ground-nesting birds such as terns, spoonbills and gulls.
This is why we carry out specialised predation management. The measures we have been implementing annually since 2020 include various deterrence tactics and hunting from a raised hide. A mobile raised hide secures the Oland dam at night to prevent foxes and raccoon dogs from crossing over.
This season, 30 employees have spent over 2,700 hours on the Oland dam and the intertidal zone of the Halligen in sun, rain, wind and water levels up to 75 cm above sea level.
This targeted intervention is essential to protect the ecological importance of these valuable breeding areas and ensure the survival of coastal bird populations.
