Partnerships for Protection

Coupon Bight Aquatic Preserve is the southernmost aquatic preserve. It is located in the lower half of the Florida Keys archipelago and lies within the boundaries of the Florida Keys National Marine Sanctuary (FKNMS). Established in 1990, the FKNMS afforded a higher level of protection through both state and federal management. Due to the increasing threats to each of the habitats that comprise the sub-tropical ecosystem of the Florida Keys, this state - federal partnership provides protection to 2,900 square nautical miles surrounding the entire archipelago of the Florida Keys, including the Coupon Bight Aquatic Preserve.
