Seagrass meadows significantly support world fisheries production and global food security, providing valuable nursery habitat for over one fifth of the world’s largest fisheries (Unsworth et al. 2019), as well as shelter and food for thousands of species including threatened charismatic species such as turtles, dugongs, seahorses and waterfowl. Recognizing the importance of seagrass ecosystems to biodiversity and human well-being (Figure 4) can help in conservation, better management and restoration of seagrass meadows.
