  1. Impacts of Inland Activities on our Estuaries: Mitigation, Improving, and Reverting the Impacts of the Past, Present, and Future

  2. Impact Sources • Population Growth • Agriculture • Pollution • Sedimentation • Traffic • Attempted Remedies • Invasives Did you know that over half of the U.S.A.’s population lives within 50 miles of the coast? That area is less than 17% of the USA’s total land mass.

  3. Removal of Water Less flushing Less dilution Little Vegetated Buffers Siltation Runoff Animal tracks Habitat Modification Rice Levees/trunks Nutrient loading Eutrophication Dead Zones Agriculture Why is this “Dead Zone” Here???

  4. Large debris Plasticland Nutrient loads Agriculture (Eutrophication) Chemicals Drains Sewage treatment Hormones How are these things involved in impacting the estuary? Pollution

  5. Construction Road building Population centers Agriculture Vegetated buffers Animal Tracks Fecal coliform Humans? Farm animals? Wild animals? Displacement Estuaries are supposed to trap small amounts of sediment. Right? How might sedimentation directly impact an estuary. Sedimentation

  6. Wave action Erosion Siltation Loss of plant life Petroleum Large debris Plastic bottles/cans clothes Traffic Explain this to me!

  7. How Do Activities in our Estuaries Effect Inland Waters?

  8. Estuarine activities • Shipping: Estuaries are homes to our ports • Pollution • Dredging • Tourism/Recreation • Boat traffic • Impacts to wildlands • Overfishing • Estuaries provide essential habitat for marine and freshwater species

  9. Shipping lanes • Pollution • Petroleum/debris • Maintenance: • Dredging • Flow change/Salt wedge • Habitat for migratory animals including fish and birds.

  10. Overfishing • Some freshwater fish species depend upon the estuarine habitat for: • Nursery • Spawning

  11. Summary:The Butterfly Effect • Inland activities may effect estuaries since rivers flow to the sea and must cross the estuary. • Estuarine activities can effect inland waters since tides push estuarine water inland and estuarine waters are home to a plethora of wildlife
