Grey Seal Numbers in the Wadden Sea and on Helgoland in 2011-2012

Trilateral Seal Expert Group (TSEG)

In the German and Dutch Wadden Sea several aerial and boat counts are conducted during the pupping season (November-January) whilst on Helgoland (Germany), surveys are carried out from land. Two dedicated grey seal aerial surveys are carried out during the moult (March-April). In the Danish Wadden Sea grey seals are only counted during the summer counts for harbour seals.
