San Felasco Hammock is a designated National Natural Landmark by the National Park System. For more information, see National Natural Landmark.

San Felasco Hammock was purchased in 1974 under Florida's Environmentally Endargered Lands Program because of its diversity of plant communities and geological features. Now at over 7,000 acres, San Felasco Hammock Preserve State Park is one of the largest protected contiguous stands of mesic hammock in Florida. It exemplifies the principal that the larger a habitat is, the more species it will support. For example, of the 45 species of birds that breed in north Florida's hardwood forests, all breed in San Felasco Hammock Preserve State Park. No other forest in Florida can claim this distinction.

The limestone outcrops and changes in elevation provide conditions for at least 18 biological communities, including areas of sandhill, hydric hammock, upland pine, and swamp. Sinkholes, steephead springs, ponds, and small lakes dot the landscape. Blues Creek, Turkey Creek, and Cellon Creek enter San Felasco from outside the park boundary and flow through the park, dropping into swallows, which drain into the aquifer.
