Mechanism
Once the woody canopy exceeds approximately 20 percent and is taller than three feet, a threshold will have been crossed to the Shrubland State (2). In this case energy in the form of heavy equipment and/or herbicides will be required along with prescribed grazing to shift the plant community back to the Grassland State (1).
Mechanism
The Grassland Savannah State (1) can be converted to the Seeded State (3) by controlling the brush and seeding to native or introduced grasses. It may also be plowed and converted to cropland.
Mechanism
Brush management is the key driver in restoring Shrub/Woodland State (2) back to the Grassland Savannah State (1). Reduction in woody canopy below 20 percent will take large energy inputs depending on the canopy cover. A prescribed grazing plan and prescribed burning plan will keep the state functioning.
Mechanism
The Shrubland State (2) can be converted to the Seeded State (3) by controlling the brush and seeding to native or introduced grasses. It may also be plowed and converted to cropland.
