Seagrass meadows fringe many temperate and tropical coasts and provide a range of ecosystem services, such as sediment stabilization, nutrient recycling, carbon sequestration and a habitat and/or nursery ground for numerous marine species including economically important fish. Seagrass meadows are worldwide in decline as a consequence of eutrophication & pollution, physical destruction (e.g., dredging, coastal development, boat moorings) and global warming.
