Target ecosystem state
Select a state
Description
One community exists in the Savannah State, the Tallgrass/Wax Myrtle Community. The site is dominated by warm season perennial grasses and has a presence of 5 to 10 percent woody species intermixed.
Submodel
Description
One community exists in the Shrubland State, the Wax Myrtle/Blackberry Shrubland Community. The state is defined by woody canopy cover from 20 to 40 percent. Herbaceous production is limited compared to the Savannah State (1).
Submodel
Description
One community exists in the Woodland State, the Cottonwood/Elm Community. The site is defined by woody canopy cover over 40 percent. The site has reduced herbaceous production compared to the Savannah and Shrubland States.
Submodel
Mechanism
The driver for this transition is abandonment, lack of fire, and/or lack of prescribed grazing. Woody species are allowed to continue to grow until reaching over the threshold of 20 percent. This signifies the transition to the Shrubland State.
Mechanism
Prescribed grazing, periodic fire, and brush management are practices that will restore the site back to the reference state. The key to successful restoration is controlling the growth of woody species throughout the site.
Mechanism
The driver for the transition to the Woodland State is further abandonment, lack of fire, and lack of prescribed grazing. The woody species have grown to a canopy cover greater than 40 percent, which signifies this transition.
