Ecological Reserves (ERs) are the largest of the sanctuary zones and are able to protect an entire range of marine habitats found in Florida Keys National Marine Sanctuary. These large, contiguous, diverse habitats help protect natural spawning, nursery, and permanent-residence areas needed for sustainable populations of fish and other marine life.
There are currently two ERs in the sanctuary, the Western Sambo Ecological Reserve and the Tortugas Ecological Reserve, which together protect nearly 160 square nautical miles. The Tortugas Ecological Reserve is separated into two parts, Tortugas South and Tortugas North.
Regulations for ERs limit consumptive activities while continuing to allow activities that do not threaten resource protection.
In addition to activities prohibited by sanctuary-wide regulations, with certain exception, the following activities are prohibited in Ecological Reserves:
- Discharging any matter except cooling water or engine exhaust.
- Fishing by any means; removing, harvesting, or possessing any marine life.
- Touching or standing on living or dead coral.
- Anchoring on living or dead coral, or any attached organism.
- Anchoring when a mooring buoy is available.
Additional regulation for the Tortugas South Ecological Reserve:
- Vessels may only enter if they remain in continuous transit with fishing gear stowed (diving and snorkeling are prohibited).
Additional regulations for the Tortugas North Ecological Reserve:
- Access permit required to stop or use a mooring buoy.
- Anchoring is prohibited.
- Mooring by vessel(s) more than 100 feet in total or combined length overall is prohibited.
- No access permit necessary if vessel remains in continuous transit with fishing gear stowed.
