Description
This is the reference or diagnostic state for the site. The description is based on early range site descriptions, clipping data, professional consensus of experienced range specialists, and analysis of field work.
Submodel
Mechanism
If the water table drops below the rooting zone for many species in State 1 for long periods (multiple years), the site will transition to state 2.
Mechanism
With hydrology restored and the water table elevated to the rooting zone, the site may be restored to state 1.
Mechanism
Many of these sites are converted to cropland through cultivation. Soil properties and hydrology have been altered significantly.
