Marine Debris
Florida Keys
Why is it a concern?
Increasing levels of debris in both the ocean and at the land-sea interface are of growing concern to stakeholders of the Florida Keys National Marine Sanctuary (FKNMS). Marine debris in the form of derelict fishing gear can destroy benthic organisms, entangle both benthic and mobile fauna, and reduce the structural complexity of habitats. Currents associated with strong storms can move debris onto reefs, where corals and other benthic organisms are damaged or killed. In 2005, it was estimated that approximately 300,000 lobster traps were lost during a series of hurricanes and strong storms. The ecological impacts caused by hook-and-line fishing gear that is lost when cut or broken after snagging on the bottom is also a growing concern to managers and stakeholders.
Surveys of marine debris in the sanctuary have found that types causing the greatest degree of abrasion damage to sessile invertebrates such as sponges and corals were hook-and-line gear (68%), especially monofilament line (58%), followed by debris from lobster traps (26%), especially rope (21%). A concerted effort to document the spatial extent, amount, and impacts of marine debris in 2008 indicated derelict angling and trap gear is ubiquitous in the sanctuary, even within no-take zones. The sheer amount of debris recovered annually is testament to an increasingly visited and exploited marine ecosystem.
Overview of Research
Research conducted by Sanctuary scientists and partners provides critical information to address existing and emerging resource conservation and management issues. The Overview of Research highlights some, but not necessarily all, of the research activities completed or ongoing at the Sanctuary.

Science Needs and Questions
The best available science is used by Sanctuary scientists and managers working to address priority resource conservation and management issues. As priorities change and new issues emerge, each Sanctuary develops new science needs and questions and works with partners to address them.
- What are the accumulation rates of marine debris within the sanctuary?
- Are certain areas of the sanctuary more or less susceptible to marine debris accumulation and/or impacts?
- Are there critical habitat areas that should be prioritized for marine debris removal efforts?
