Ochlockonee River State Park's primary ecologic biome is
East Gulf coastal plain near-coast pine flatwoods, with some
live oak thickets also present within the park boundaries; The park is considered to be one of the best remaining examples of a natural flatwoods environment in the state, and it contains a significant habitat for the endangered
red-cockaded woodpecker, which nests in
longleaf pines. In addition to a large number of other birds, The park's location at the top of Ochlockonee Bay is within a
tidal estuary, with
fresh water from the Ochlockonee and Sopchoppy Rivers mixing with
tidal salt water from the
Gulf of Mexico to produce a
brackish environment, inhabited by both fresh and saltwater fish.
Largemouth bass,
bream,
catfish,
speckled perch, and other fish are found in the
brackish river waters, along with
blue crabs. ==Recreational activities==
