Global Distribution of Seagrasses (Polygons)

Seagrass is found on all continents except Antarctica, covering roughly 0.1% of the ocean floor. However, its global extent remains inadequately mapped, with estimates varying between 160,387 km² and 670,000 km², posing a significant challenge for conservation efforts. The UNEP-WCMC seagrass dataset indicates that Africa harbors approximately 12% of the world’s seagrass.
