Dunes & Maritime Forests by Justin & Jordan

SUBSTRATE-The surface on which a plant or animal lives

  • Sandy

  • Sometimes mixed with calcium carbonate

  • linear barrier islands

  • typically contain parallel zones of upper beach, undulating foredune

  • transition or "backdune," and stable dune, sloping upward and away from the water's edge.

Processes/Dynamics/Abiotic Factors

  • Wind- and wave-driven sand interact with pioneer grasses to build dunes

  • Waves from hurricanes may destroyed dunes.

Human Impact


  • Development of beach front, with greatest impacts near Ft. Walton, Jacksonville, Palm Beach, Ft. Lauderdale, Miami, and Clearwater-St. Petersburg

  • By 1975 nearly 20% of Florida's barrier islands had been developed; exotic plants such as Australian pine, Brazilian pepper, and sisal are also a serious problem.

  • Non-native plants are killing off native plants.
