PRESERVING OUR WETLANDS

This presentation delves into the significance of wetlands within the Madison County Park System. It covers various types of wetlands, including freshwater marshes, tidal marshes, fens, bogs, swamps, mangrove flats, and floodplains. Learn about the critical characteristics and benefits of wetlands such as biodiversity, flood control, and nutrient retention. The presentation highlights alarming trends in wetland loss, driven by agricultural expansion and urbanization, with 80% lost in the U.S. and 50% globally. Understand the severe impacts of wetland loss on flood severity, water quality, and wildlife habitats.

  1. PRESERVING OUR WETLANDS A Presentation of theMadison County Park System

  2. Types of Wetlands • Freshwater marshes • Tidal marshes • Fens • Bogs • Swamps • Mangrove flats • Floodplains and deltas

  3. Wetland Characteristics

  4. Benefits of Wetlands • Wetlands are regions where soils, water, plants, and animals interact • These interactions generate healthy wildlife, fisheries, and forest resources • Flood control • Shoreline and storm protection • Nutrient retention and export

  5. Mammals in the Wetlands

  6. Wetland Loss • Historic approach has been to drain wetlands to convert land for agricultural use • Approximately 80% of U.S. wetlands have been lost to agriculture • Approximately 50% of wetlands worldwide have been lost

  7. Local Wetland Losses

  8. Local Wetland Losses

  9. Rate of Wetland Loss

  10. Impacts of Wetland Loss • Floods—more damage to areas that were once wetlands • Water quality—more sediments, nutrients, and contaminants downstream • Animal habitats—loss of habitats for animals that inhabit wetlands
