EG-Marine Mammals harbour seal surveys in the Wadden Sea and Helgoland in 2020-2021: Harbour seal population size in the Wadden Sea plateaus close to the level it was in 1900 ...
The harbour seal counts are synchronised to the degree possible between the three Wadden Sea countries, Denmark, Germany and the Netherlands, in order to obtain a combined estimate for the number of harbour seals and newborn pups in the entire Wadden Sea and Helgoland. Harbour seals are counted when...

The harbour seal counts are synchronised to the degree possible between the three Wadden Sea countries, Denmark, Germany and the Netherlands, in order to obtain a combined estimate for the number of harbour seals and newborn pups in the entire Wadden Sea and Helgoland. Harbour seals are counted when hauling out on land and counts are scheduled to be carried out when low tide occurs around midday. The counts are carried out on five coordinated dates. The counts are carried out on five coordinated dates: three counts during the pupping season in June and two during the moulting season in August. In June the number of pups is counted and in August the total number of harbour seals is counted in the respective regions.The variation in the number of seals hauling out from year to year and over longer periods may be affected by different weather conditions, disturbance, distance to food patches, or a change in the age and sex composition of the population (Härkönen et al. 1999).
