St. Marks Mitigation Bank (SMMB) is a 1,450-acre wetland site that straddles Jefferson and Wakulla Counties.   The bank site is an ideal location, adjacent to a vast assemblage of conservation lands alongside the St. Marks and Aucilla River drainages.

This UMAM assessed bank serves as viable compensatory mitigation for projects which impact flatwood, prairie, and hardwood wetlands. Substantial portions of the mitigation bank site include areas identified as potential rare species habitat. Specifically documented plant and animal occurrences within a 6-mile radius of the proposed bank include: Florida Black Bear, Suwannee Cooter, Alligator Snapping Turtle, Spotted Turtle, Bald Eagle, One-toed Amphiuma, Eastern Indigo Snake, White-flowered Wild Petunia, Incised Groove-bur, Chapman’s Sedge, Curtiss’ Sandgrass, Corkwood, Beaked Spikerush, Godfrey’s Spiderlily, and Thorne’s Beakrush.

In addition, the U.S. Fish and Wildlife Service has recently listed the area as critical habitat for the flatwoods salamander. Several areas of known breeding ponds or observed adults have been documented within a 5-mile radius of the proposed bank location.

SMMB, located in the St. Marks River Basin,  services portions of Wakulla, Jefferson, and Leon Counties.
