GR: Kelp and seagrass form critical habitats within marine ecosystems. Both grow in shallow water where they serve as essential habitat for animals, and important nutrient recyclers. Compared to terrestrial vegetation, we know little about these vegetation types. Biogeographers have mapped general distributions, but they have not made detailed maps of species associations.
The seagrass vegetation map accompanies a report on the decline of seagrass due to pesticides washing from the land into the ocean. The infographic below shows the distribution of seagrass genera in various habitats. The authors point out that there have been few attempts to restore destroyed seagrass meadows. Most attempts have failed.
