Description
The dominant vegetation is allscale saltbush (Atriplex polycarpa) with a broad uniform spacing. During the spring if sufficient levels of moisture are available a variety of annual forbs and grasses will grow for short periods, the rest of the year >25% bare ground is common
Submodel
Description
This state has varying levels of saltbush and high levels of invasive species.
Submodel
Description
This community phase represents all the varied land uses that significantly alter this ecological site. This is an extremely varied community phase that includes all types of alterations that so significantly alter the ecological site that it is permanently changed and no longer has typical or even representative ecological dynamics.
Submodel
Mechanism
This transition was caused by unsustainable levels of grazing and invasion by introduced annual species.
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 only when significant time and money inputs are focused on returning ecological function and native seed source to 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.
Mechanism
This restoration pathway occurs only when significant time and money inputs that would require constant maintenance and weed management and should be focused on areas that have not been permanently altered by urban developments.
