Abstract

The Wadden Sea areas in Denmark, Germany and the Netherlands were surveyed for grey seals (Halichoerus grypus) during the pupping season (November 2019 –January 2020) and during the moulting period (March-April 2020) by means of coordinated aerial surveys and in the case of Helgoland, by land based counts. These surveys provide data on the changes in grey seal occupancy of the area and changes in the local breeding population. In part, the grey seals observed in the Wadden Sea during the moult may breed in the UK where the largest part of the greater North Sea population are observed (~100.000 individuals).

Abstract

During the grey seal (Halichoerus grypus) pupping season in the winter of 2014-2015, the Danish, Dutch and German Wadden Sea areas were surveyed by means of coordinated aerial and boat counts. On Helgoland (Germany), surveys were carried out from land, whilst in Schleswig-Holstein the pup counts were conducted either from land or by boat. Furthermore, in the spring of 2015, dedicated grey seal aerial surveys were carried out during the moulting period (March-April) throughout the Wadden sea area. For the Danish Wadden Sea it was the first time that dedicated grey seals surveys were performed.
