Description
This state includes the Historic Climax Plant Community (HCPC). This site is characterized as a perennial grassland with a few scattered shrubs and forbs.
Submodel
Description
This plant community is characterized as a perennial grassland with introduced non-native annuals.
Submodel
Description
The factors that may contribute to a disturbed state include prolonged drought, unmanaged grazing, off road vehicle use, and other possible disturbances. There is a loss of soil surface stabilty and hydrologic function as perennial herbaceous cover is removed. The soil surface has been severly degraded or lost, exposing the more sodic soil layer. This plant community has lower capability to capture and store moisture and now erodes readily.
Submodel
Mechanism
Introduction and establishment of of exotic annual grasses and forbs.
Mechanism
Disturbance to soil surface; drought; repeated fire; continuous improper grazing. Loss of soil stability and hydrologic function.
Mechanism
Normal precipitation patterns for several years good management of grazing, vehicles, and other disturbances that reduce herbaceous cover or disturb the soil on the site will allow the dunes to stabilize and revegetate. Planting may help stabilize critical areas.
