The scope encompasses managing hydrilla, floating plants, and nine additional invasive species across designated water bodies including the Little Wekiva River, Rock Spring Run, and Blackwater Creek, with objectives to maintain navigation, protect native habitat, and reduce impacts from invasive species.
