Wetlands

Until recent years, wetlands were believed to be of little value, and were drained for other uses. Florida, with an estimated historical coverage of 54% wetlands, has lost over half of these precious ecosystems. Wetlands aid in pollution sequestration, flood control, and erosion prevention, not to mention wildlife habitat rich in biodiversity. Between the 1930s and 1970s, the St Johns River lost over 60% of its nearly 290,000 acre wetland coverage, leading to increased pollution and flooding problems, as well as precious habitat loss. The largest uninterrupted wetland habitat in the St Johns basin is the Three Forks Marsh and Blue Cypress Conservation areas, with over 100,00 acres. Nine distinct wetland habitats can be found within the St Johns River basin, including Hardwood Swamps, Deep Marshes, and Seepage Slopes. (Dahl, Hefner)
