Submodel
Mechanism
The Mid and Shortgrass Savannah Community (1.2) is reversible with grazing management and prescribed burning practices until brush canopy exceeds 40 percent. When woody plant canopy exceeds 40 percent, the plant community crosses over to a threshold identified as the Brushland State. The Mixedbrush/Shortgrass Community (2.1) within the Shrubland State is not reversible to the Mixed Prairie Community (1.1) without extensive and expensive inputs.
Mechanism
Brush management, pasture planting, range planting, and crop cultivation are some conservation practices that can shift from the Grassland State to the Converted Land State.
Mechanism
Alternatives for restoration include: (a) brush management and seeding to return vegetation and grazing management and prescribed fire to maintain the desired community; (b) brush management, cultivation and cropping with adapted crops and/or (c) brush management and seeding with introduced pasture species followed by proper grazing and pasture management.
