The Trilateral Governmental Conference is a quadrennial meeting of the members of the Trilateral Wadden Sea Cooperation to map their course for the subsequent years until the next conference.

Every three to four years, national and regional authorities, scientific institutions, and environmental NGOs engage in topics of paramount importance for the protection of the Wadden Sea World Heritage Site.

With the establishment of the Wadden Sea Flyway Initiative (WSFI) in 2012, Denmark, Germany and the Netherlands recognized their specific responsibility to contribute to conserving migratory waterbirds along the entire flyway.

Small and medium sized enterprises (SMEs) often lack access to business tools that could help them enhance their sustainability. This is especially true in business ecosystems where interactions, access to knowledge and exchange, happen on a (s)lower scale, such as in the Wadden Sea protected areas region.

Harbour seals, the most well-known seal species in the Wadden Sea, are monitored annually through aerial surveys that cover the entire Wadden Sea World Heritage site and the island of Helgoland.

The trilateral Wadden Sea Plan was adopted at the 8th Trilateral Governmental Conference in Stade in 1997.
