Description
The Reference State is valley oak woodland.
Submodel
Description
This state represents a change is site hydrology and the lowering of the water table.
Submodel
Mechanism
This transition is caused by the lowering of the summer water table to a depth and for a duration such that it the ecological site crosses a threshold, causing the function and structure of the site to change.
Mechanism
This transition is caused by significant human alterations that force this ecological site over a threshold and change the function and structure of this site in extensive ways.
Mechanism
This restoration pathway occurs when the water table is restored. In the case of prolonged drought this may occur naturally, but in most instances significant time and money inputs will be required to return the ecological function of the site.
Mechanism
This transition is caused by significant human alterations that force this ecological site over a threshold and change the function and structure of this site in extensive ways
