Habitat quality for Grey Seals in the Dutch Wadden Sea

Brasseur, S.M.J.M.; Aarts, G.M.; Kirkwood, R.J.


Growth in numbers has seen the Netherlands become a strong-hold for grey seals in continental Europe. This report has the following subjects (questions posed by the Dutch Ministry): β€œIs a favourable status of the habitat quality of the grey seal in the Netherlands dependant on the presence of undisturbed, permanently dry breeding sites, or do the current sites, which are considered sub optimal, suffice for a long term survival of the species in the Netherlands?” and "How is the growth influenced by immigration from other areas (i.e. the UK)?”
