Presentation Transcript

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.



Barrier island
Barrier Island productivity occurs along coastal areas. These areas include mangroves, salt marshes, tidal zones and sea grass beds.

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


Coral reef
Coral Reef productivity occurs along coastal areas. These areas include mangroves, salt marshes, tidal zones and sea grass beds.

One of the worlds most biologically diverse ecosystems

42% at low risk

31% at medium risk

27% at high risk


Open ocean
Open Ocean productivity occurs along coastal areas. These areas include mangroves, salt marshes, tidal zones and sea grass beds.

  • 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.
