Harbour and Grey Seal Numbers in the Wadden Sea and on Helgoland in 2006

As in the foregoing years, in 2006 the surveys to monitor the harbour seal Phoca vitulina population in the entire Wadden Sea were coordinated and carried out trilaterally according to the Seal Management Plan.

This is the first time that we report on trilaterally coordinated surveys on grey seals in the Wadden Sea. We therefore introduce this species and report on this year’s counts.
