Description
The Reference State represents the historic range of variability for this ecological site. The ubiquitous naturalization of non-native species in the Mojave Desert has converted the Reference State to a Representative State. Periodic drought and water erosion are the natural disturbances influencing this ecological site.
Submodel
Description
State 2 represents the current range of variability for this site. Non-native annuals are naturalized in this plant community. Their abundance varies with precipitation, but they are at least sparsely present within the current year's growth or in the seedbank.
Submodel
Mechanism
Introduction of non-native species due to a combination of factors including; surface disturbance, changes in the kinds of animals and their grazing patterns, drought, changes in fire history or any other type of vegetation removal. Non-natives can alter disturbance regimes significantly from their natural or historic range and change ecological processes therefore creating an unlikely scenario to restore the site back to reference.
