State 1
Reference
Description
The reference state is considered to be representative of the natural range of variability under pre-Euro settlement conditions. This state is characterized by a Mid and Tallgrass Savannah community.

State 2
Oak/Juniper Woodland State
Description
The Oak/Juniper Woodland state has juniper and oak as co-dominates.

Mechanism
This Transition reflects the crossing of a threshold into a different vegetative state. This transition is driven by a lack of fire, no brush management and no prescribed grazing.
Mechanism
The recovery is driven by significant inputs of energy from equipment such as skid loaders, bulldozers, or other brush management equipment. Slope and rockiness will preclude some equipment. Only hand equipment can be used on the steeper slopes. Usually at this state, prescribed fire is a high risk option.
Mechanism
Mechanical conversion of primarily juniper canopy to a mulch cover restores the energy flow to the remaining species, usually oak. The hydrologic cycle retains nearly all the rainfall because of the heavy mulch. Little evaporation takes place.
