About 395,000 breeding pairs of coastal breeding birds occur in the transnational Wadden Sea, of which 75% inhabit the islands and Halligen.

In January 2020 the third Total Count of the East Atlantic Flyway was organized. The now published compilation of national reports gives a first overview of the bird numbers counted in 32 countries along the Flyway.

On 19 November 2020 the Wadden Sea Board chair, members and advisors as well as the Common Wadden Sea Secretariat (CWSS) came together in a 2-hour online session.

In August 2020, 28,352 harbour seals were counted in the Danish-Dutch-German Wadden Sea and Helgoland. This is the highest count yet recorded since 1975.

Due to the ongoing pandemic, the ISWSS15 will now take place on 30 November to 3 December 2021.
