Description
This State is native tall grass prairie dominated by little bluestem, switchgrass and forbs, but also a substantial component of wet tolerant sedges. This State occurs on level to gently sloping soils that have a seasonal high water table that is perched above the abrupt textural change or clayey subsoil during the spring months in most years. This condition influences the species composition and site productivity. 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 gray dogwood and eastern redcedar. When fire intervals shorten these woody species will decrease.
This State is extremely rare. Nearly all sites have been converted to cool season grasslands and cropland.
Submodel
Description
Degraded Reference States that have experienced fire suppression for 20 or more years will transition to this State. With fire suppression, woody species such as pin oak and eastern redcedar will begin to dominate transitioning this state from a prairie to a Woody Invaded Savanna. Native ground cover will also decrease and invasive species such as tall fescue may begin to dominate. Transition to cool season grasslands (State 3) or intensive 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 the Missouri Central Claypan area. Occasionally, these pastures will have scattered pin 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.
Submodel
Description
This is the dominant state that exists currently with intensive cropping of corn, soybeans, and wheat 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. Most sites have installed surface drainage systems to mitigate wetness problems.
Submodel
Description
Conversion from the 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 is the most easily transformable state back to a Reference State. Substantial restoration time and management inputs will be needed.
