Workshop: How much salt marsh management do we want and need in a changing climate?

Salt marshes constitute an inherent part of the Wadden Sea World Heritage Site. Apart from their natural values, they deliver significant ecosystem services by storing carbon dioxide and for coastal flood defense.

Salt marshes are protected and managed differently in the three Wadden Sea countries Denmark, Germany, and the Netherlands. Passive (hands-off) and active management, the latter with different levels of intervention, are being conducted for multiple purposes: to enhance biodiversity actively, to support coastal flood defense (Nature based Solution), agriculture, etc. Climate change induced stronger sea level rise will affect salt marshes.

With the workshop "Nature conservation and coastal flood defence: How much salt marsh management do we want and need in a changing climate?" we would like to bring together ecologists, and engineers, site managers, scientists and decision-makers in the field of nature conservation and coastal protection for Wadden Sea salt marsh conservation and management, and enable them to exchange and learn from each other. While we focus on the Wadden Sea area, experts and stakeholders from other regions, in particular from the North Sea Region, are welcome to enrich the discussion.

The final programme of the workshop on 10 October 2024 is here.

An outline of the excursion on 11 October 2024 is here.
