The central focus of work package 5 is on investigating and understanding biogeomorphic feedbacks in vegetated ecosystems that inhabit the inter-tidal zone of the Wadden Sea. With a focus on the adaptive capacity and response of inter-tidal vegetation to abiotic conditions we aim to better integrate biotic processes into long-term predictions of habitat dynamics. This work will contribute to the integration of nature-based solutions in coastal defence by improving predictions of habitat dynamics that can impact habitat capacity for hydrodynamic energy attenuation and sediment retention. 

The impact of abiotic stressors, such as wave action, on vegetation morphological traits including flexibility, height, diameter, density, and biomass allocation will be isolated and observed in field and laboratory experiments. Greenhouse experiments and novel monitoring techniques will be employed to carry out long-term, continuous monitoring. This will be used to develop new models of dynamism and regulatory service capacity of intertidal habitats in a changing climate.
