Project Seagrass

Advancing seagrass conservation through education, influence, research and action  


At Project Seagrass, we recognise that the pressures on our oceans are urgent, and that we can't afford to do seagrass research purely for sake of it! Since day one our seagrass research has been geared towards making an impact in the real world.  

The Seagrass Ecosystem Research Group (SERG), is a joint inter-disciplinary marine research collaboration between marine biologists in the school of Biosciences at Swansea University, and interdisciplinary marine scientists at the Sustainable Places Research Institute, Cardiff University

Our team conduct basic and applied research into the structure, function and resilience of seagrass meadows, within a linked social ecological system, they also focus on their food provisioning service.
