About the Species
Johnson's seagrass plays a major role in the health of "benthic" (anything associated with or occurring on the bottom of a body of water) resources as a shelter and nursery habitat.

Johnson's seagrass was the first—and only—marine plant species to be listed under the Endangered Species Act. It is listed as threatened under the ESA.
NOAA Fisheries is committed to conserving and protecting Johnson’s seagrass. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.
- Throughout Its Range
