Wetlands

Wetlands

  • Wetlands contain fresh water for part of the year

    -trap and filter sediments and pollutants

    -protect shorelines from erosion

    -spawning grounds for many commercially important species

    -habitat for rare and endangered animals and plants

  • Includes marshes and swamps

  • Act as transitional areas between freshwater and saltwater


Marine ecosystems

Marine Ecosystems

  • Estuary (FW and SW)

  • Salt marsh

  • Mangrove swamps

  • Barrier Islands

  • Coral reef

  • Open ocean


Estuary

Estuary

  • area where freshwater from a river meets salt water from the ocean

    -very productive ecosystems

    -rich in nutrients and minerals

    -plenty of sunlight (shallow water)

Salt marsh

Salt marsh

  • Develop in areas where estuaries deposit nutrient rich mud

  • Characterized by marsh grass

  • Provide support for clams, fish, crabs, shrimp, and aquatic birds

  • Absorb pollutants and protect

  • inland areas


Mangrove swamp

Mangrove Swamp

  • tree vegetation that grows in the muddy coastal areas between high and low water

  • mangrove forests protect the coastline from erosion; provide nursery grounds for fish, shrimp, clams, crabs and snails

  • provide food via

  • nutrient-rich mud

  • and leaf litter.


Aquatic ecosystems cont

  • Approximately one-third of all marine biological productivity occurs along coastal areas. These areas include mangroves, salt marshes, tidal zones and sea grass beds.


Barrier island

Barrier Island

  • These geographic features serve as protection for mainland and coastal wetlands


Coral reef

Coral Reef

One of the worlds most biologically diverse ecosystems

42% at low risk

31% at medium risk

27% at high risk


Open ocean

Open Ocean

  • Represents 65% of the Earth oceans.

  • Some areas of open ocean contain little or no life at all, while other areas support large numbers of species

  • Approximately 10% of all

  • marine life is found in the

  • open ocean.

Marlins, Tuna, Dolphins, Swordfish, and Sharks.
