Description
This phase is a dry/mesic oak woodland. As such, this has a reference plant community which includes trees, grasses and forbs.
Submodel
Description
The reference state will transition to this state phase due to fire suppression and timber management. A restoration path is also possible to the reference state by proper prescribed fire, extended rotations and selective thinning. The timber managed state can transition to either a high graded / grazed woodland state or to a fire managed woodland state. The high graded / grazed woodland state is formed by high-grading harvesting and uncontrolled grazing. In order to return to the timber managed state, thinning, forest stand improvement and ceasing grazing are required. The fire managed woodland is formed by prescribed fire and thinning and can return to the timber managed state by fire suppression and forest timber management.
Submodel
Description
This state has three other possible states it can change to, the timber managed woodland, the high-graded / grazed woodland and restoration to the reference state. Restoration requires extended rotations and selective thinning. Transitioning to the timber managed woodland requires fire suppression and forest timber management. High-grading harvesting and uncontrolled grazing will cause a transition to the high-graded / grazed woodland state.
Submodel
Description
The grassland state has only one possible transition, which is directly from the tall fescue – white clover / multi-flora rose phase to the black oak – hickory / black cherry – buckbrush – gooseberry –multi-flora rose / black snakeroot – geranium phase of the high-graded / grazed woodland state.
Two possible transitions to this state are from the reference state and the high-graded / grazed woodland state. Transitioning from the high-graded / grazed woodland state requires clearing, pasture planting and grassland management.
Many species are possible in this State.
Submodel
Description
This state can transition to three other possible states, the grassland state, the timber managed woodland state, and the fire managed woodland state. A transition to the grassland state requires clearing, pasture planting, and grassland management. The timber managed woodland state can be formed by forest stand improvement ceasing grazing, and thinning. Transitioning to the fire managed woodland state also requires forest stand improvement and a ceasing of grazing, but will require prescribed burning as well.
Submodel
Mechanism
Prescribed fire; extended rotations; selective thinning.
