The St. Martins Marsh Aquatic Preserve was established on October 21, 1969.
St. Martins Marsh Aquatic Preserve's freshwater tributaries includes two
1st magnitude spring fed rivers; the Homosassa River to the south and
Crystal River to the north.
Spring discharge does not fluctuate dramatically from season to season
allowing a constant flow of freshwater into St. Martins Marsh's productive
and well-balanced estuary.
The area's vast coastal salt marshes, mud flats, oyster bars, mangrove
islands, and seagrass beds are the southern terminus for migratory
waterfowl of the Atlantic and Mississippi flyways. St. Martins Marsh
provides stopover and wintering areas for many migratory species.
The Springs Coast is characterized by unique limestone outcroppings
and exposed karstic features. Habitats associated with these areas are
hardbottom sponge and coral communities and sargassum meadows.
