State 1
Reference
Description
This State is native prairie dominated by little bluestem, big bluestem, and forbs, along with numerous shrubs and occasional, widely scattered, stunted trees such as post oak and blackjack oak. Two phases can occur that will transition back and forth depending on fire frequencies. Longer fire free intervals will allow woody species to increase such as post oak and eastern redcedar. When fire intervals shorten these woody species will decrease.
This undisturbed State is uncommon but some excellent examples still exist. Most sites, however, have been converted to cool season grasslands, cropland, or degraded by domestic grazing.
Submodel
Description
Reference States that have experienced fire suppression for 20 or more years and heavy domestic grazing will transition to this state. With fire suppression, woody species such as post oak and eastern redcedar will begin to increase transitioning this state from a prairie to a woody invaded state. Native ground cover will also decrease and invasive species such as tall fescue and sericea lespedeza may begin to dominate. Transition to cool season grasslands (State 3) or cropland (State 4) is very common.
Submodel
Description
Conversion of other states to non-native cool season species such as tall fescue and red clover has been common in this area. Occasionally, these pastures will have a few scattered post oak and eastern redcedar. Long term uncontrolled grazing can cause significant soil erosion and compaction. A return to the reference state may require a very long series of management options.
Submodel
Description
This is a common state that currently exists in the region with milo, wheat, and hay land production occurring. Some conversion to cool season grassland occurs for a limited period of time before transitioning back to cropland. Limited acres are sometimes converted to native warm season grassland.
Submodel
Description
Conversion from Degraded Native Grassland (State 2) Cool Season Grassland (State 3) or the Cropland (State 4) to this State is increasing due to renewed interest in warm season grasses as a supplement to cool season grazing systems or as a native restoration activity. This State, once established, is the most easily transformable state back to a Reference State. Substantial restoration time and management inputs will be needed.
