Parallel to coastal protection, measures for nature conservation are undertaken to eliminate invasive aliens from the natural ecosystems that take over.

We consider the elimination of S. acutifolia from its spontaneous locations as a reduction in both its erosion-control services and the willow’s role in nature conservation. We present some principles for action in case of a conflict between coast protection and nature conservation.
