Florida's Coral Reef Disease Outbreak

Scientists, policy makers, and the public are responding to a disease event affecting the continental United States' only living barrier reef.

Florida's Coral Reef is experiencing a multi-year outbreak of stony coral tissue loss disease. While disease outbreaks are not uncommon, this event is unique due to its large geographic range, extended duration, rapid progression, high rates of mortality and the number of species affected. The disease is thought to be caused by bacteria and can be transmitted to other corals through direct contact and water circulation. Researchers are working to identify potential pathogens and relationships with environmental factors, strategies to treat diseased colonies, and identify genotypes of corals that are resistant to the disease.

Economic Impact

Florida's Coral Reef ecosystem supports 70,000+ jobs equaling $8.5 billion in sales and income annually.

In the Florida Keys, 58% of all jobs are tied to the reef with marine activities generating $3.38 billion in sales and income annually.

The reef is a natural buffer for Florida's shoreline, lessening the strength of waves and protecting human life and property.

The Coral Reef Economy is bigger than you think.
