Submodel
Description
Composition is altered from the reference state depending on tree selection during harvest. This state will slowly increase in more shade tolerant species and bur oak will become less dominant. Without periodic canopy disturbance, stem density and fire intolerant species, like hackberry, will increase in abundance. Some periodic grazing may be occurring.
Submodel
Description
Conversion of other states to non-native cool season species such as tall fescue, orchard grass, and white clover has been common. Occasionally, these pastures will have scattered oaks. Long term uncontrolled grazing can cause significant soil erosion and compaction. A return to the reference state may be impossible, requiring a very long-term series of management options and transitions.

Mechanism
Lack of disturbance events greater than 20 years ; repeated timber harvests.
Mechanism
Woody removal; tillage; vegetative seeding; grassland management.
