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. It has been documented as a food source for endangered West Indian manatees and threatened green sea turtles. 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
We published a final rule to list Johnson's seagrass as threatened under the Endangered Species Act in 1998. We designated critical habitat on April 5, 2000. In addition, we published a recovery plan for the species on October 4, 2002.
Johnson's Seagrass may have the most limited distribution of any seagrass on earth, known to only occur...
