What is the name of our special grass?
Smooth cordgrass!
What is erosion?
The gradual wearing away of land surface materials, especially rocks, sediments and soils by the action of water, wind or glaciers.
What is a watershed?
A watershed is an area in which all water, sediments, and dissolved materials drain from the land into a common body of water.
The wearing away of the cliff or rock where the arch is.
What type of natural process do you think eroded this?
What is a salt marsh?
A coastal wetland which contains grasses and other vegetation that tolerate saltwater.
How might humans cause erosion?
Construction, Sea walls and Removal of native vegetation
Where is the largest source of freshwater in our watershed?
The Choctawhatchee river!
The steep drop off of sand/land
What salinity does smooth cordgrass grow in?
10 ppt to 20 ppt
How does smooth cordgrass help prevent erosion?
The roots of the plant are able to hold onto the soil so less or no sediment washes away.
What type of water is in the Choctawhatchee Bay?
Brackish water.
The roots of the trees are fully exposed and above ground
What are the three reasons smooth cordgrass is important?
It helps prevent erosion, provides habitat and filters and absorbs pollution.
How do oyster reefs help build the shoreline?
They create a natural barrier that slows the wave energy.
What state is most of the Choctawhatchee watershed in?
Alabama!
Remember only 42% of our watershed is in Florida, the rest drains from Southeastern Alabama.
Steep drop off of land right underneath the houses
What are some solutions to helping prevent and restore shoreline erosion?
Planting smooth cordgrass and building oyster reefs.
How might erosion impact plants and animals that rely on the salt marsh?
Why do we measure small concentrations of water in our watershed?
Small changes in concentrations can have a BIG impact on the habitat in our watershed.
Water and wind has eroded these landforms into these shapes.
