Importance of Wetlands & Their Preservation
What is a wetland? • Marsh: soft-stemmed vegetation • Swamp: woody plants • Bog: freshwater, spongy peat, evergreens, mossy floor • Fen: freshwater, peat-forming, covered in grass, reeds, and wildflowers www.nwi.fws.gov
Wetlands: • The link between the land and water • An ecosystem characterized by: -hydrology -soils -vegetation • “Nurseries of life”
Prevent/reduce flooding Improve water quality Fishing Maintain biodiversity and aesthetics Reduce soil erosion Serve as ground water recharge areas Make wonderful outdoor classrooms! What Wetlands do for you:
Despite all of these benefits, 60,000 acres of Wetlands are lost each year, in the US alone • The Clean Water Act of 1972: • Goal: To restore and maintain the chemical, physical, and biological integrity of the nation’s waters • Support: “the protection and propagation of fish, shellfish, and wildlife and recreation in and on the water” • The Act does not deal with ground water or water quantity issues • It employs ways to sharply reduce pollutant discharge, finance wastewater treatment, and manage runoff
Reversing the impact of degradation “The nation behaves well if it treats the natural resources as assets which it must turn over to the next generation increased, and not impaired, in value. -Theodore Roosevelt • Wetland Mitigation: -improvement upon wetlands that is made as exchange for damage done to wetlands elsewhere • Restoration: -returning one of the wetland characteristics to a drained wetland site • Creation: -impounding water to excavated, depressed areas that did not previously contain wetland soils or vegetation
Mitigation • 1980’s President Bush> “no net loss” • Each developer must first obtain a permit before beginning construction • “no net loss” policy fails • Index of Biotic Integrity (IBI) • Army corps of Engineers>enforce • Fish and Wildlife Service>consultants
REstoration • Provides landowners an opportunity to benefit wildlife, themselves, and community -USDA Natural Resource Conservation Service (NRCS) & Wetlands Reserve Program • Takes place where hydric soils remain • From 1982-1992 768,700acres of wetlands gained
CREATION • All 3 characteristics are missing • Difficult, costly, and often unsuccessful • A Success Story: -NHC/DEM Landfill, treating leachate -awarded CAMA grant from NC division of Coastal Management -lowers costs, and reduces 60,000gal of discharge from entering Cape Fear
