Florida Keys National Marine Sanctuary

The Florida Keys National Marine Sanctuary protects a large expanse of coral reefs, seagrass beds, and coastal habitats in Florida's southern waters. It encompasses diverse marine environments ranging from shallow bays to deeper offshore waters and supports thousands of marine species.

The sanctuary was established in 1990 to protect marine resources after growing concerns about reef damage and degradation. This designation marked an effort to preserve these ecosystems as human activities increased in the region.

The name reflects the Keys region and its deep connection to the sea. Visitors notice signs of fishing traditions and how the community has long depended on these waters for their way of life.

Water sports like diving and snorkeling are possible, though visitors must follow rules to protect the environment. It is important to check access points and local guidelines, as some areas may have restrictions or be off-limits.

The sanctuary contains the largest continuous seagrass meadow in the Northern Hemisphere, a feature less visible than the coral reefs but equally important. These underwater fields serve as nurseries where young fish grow before moving to deeper waters.
