Description
Site is in reference condition with seasonal variation of native annual forbs.
Characteristics and indicators
Low-laying microsites across the landscape pond during the winter.
Submodel
Description
Introduced species have suppressed native forbs.
Submodel
Mechanism
This transition is caused by the introduction of invasive grasses and forbs, which out compete native grasses for resources on upland sites and force the ecological site over a threshold.
Mechanism
This transition is caused by human practices or natural processes that disconnect the soil surface from the high water table, such as, land leveling, deep ripping and creek down cutting through the duripan.
Mechanism
This restoration pathway occurs only when significant time and money inputs are focused on removing introduced species and restoring the seedbank of native species. Grazing to low RDM levels and low intensity fire have been shown to reduce the cover of annual grasses and increase diversity, depending on timing, intensity and duration.
Mechanism
This transition is caused by human practices or natural processes that disconnect the soil surface from the high water table, such as, land leveling, deep ripping and creek down cutting through the duripan.
