The thematic report on Marine Mammals as part of the Quality Status Report 2017 (QSR 2017) provides an overview of the present status of the populations of the harbour (or common) seal Phoca vitulina, the grey seal Halichoerus grypus, and the harbour porpoise Phocoena phocoena in the Wadden Sea, based on the Trilateral Monitoring and Assessment Program (TMAP).
