Johnson’s seagrass, (Halophila johnsonii) is a species native to the Indian River Lagoon System (IRLS) and southeastern Florida coast. It is the first and only marine plant to carry the formal status of a Threatened Species under the Endangered Species Act. With this listing, this spatially and temporally dynamic plant has an elevated status of protection – which by default extends to a large portion of the coastal lagoon seafloor throughout the entire IRLS. As long as Johnson’s seagrass is listed under the ESA, many forms of coastal development are limited or prohibited and mitigation for its disturbance is not an option. We recently wrote an article for ECO Magazine (see link below) where you can learn more about this issue, along with the ins and outs of today’s DNA analysis methods.
