Florida Seagrass Die-Off Can Be Reversed, Research Says

Abundance of the seagrass, Thalassia testudinum, more commonly known as turtlegrass, a foundation species of the Florida Bay ecosystem, decreased extensively during what is considered to be one of the largest declines in seagrass cover in recent history.

Researchers from the University of South Florida, the Florida Fish and Wildlife Conservation Commission (FWC) and the University of North Carolina Wilmington documented the response of seagrasses after the die-off. Their detailed data collection for over 20 years across the large area of impact has provided unique insight into seagrass resiliency or the ability of a coastal ecosystem to recover after the extensive loss. This study, published in Scientific Reports, is extremely timely as the work provides a framework for how future recovery of a new seagrass die-off, recorded in 2015 in the same location, may still be possible.

Seagrass plays an important role across much of the Gulf of Mexico and Caribbean Sea, providing critical habitat and feeding grounds for many species of fish, turtles and other wildlife. They’re considered to be one of the most productive ecosystems in the world and in Florida Bay contribute to a sport fishing industry worth hundreds of millions of dollars per year.
