Description
State 1 represents the historic range of variability for this ecological site. This state no longer exists due to the ubiquitous naturalization of non-native species in the Mojave Desert. Periodic drought was the natural disturbance influencing this ecological site.
Data for this State does not exist, but dynamics and composition would have been similar to State 2, except with only native species present. See State 2 narrative for more detailed information.
Description
State 2 represents the current range of variability for this site. Non-native annuals, including Mediterranean grass and Asian mustard are naturalized in this plant community. Their abundance varies with precipitation, but they are at least sparsely present (as current year’s growth or present in the soil seedbank).
Submodel
Description
This state is characterized by increased rates of erosion, with an active eolian environment. This state has been significantly altered from the natural range of variability found in States 1 and 2. Increased wind erosion decreases the suitability of this ecological site for vegetation, killing established or young individuals by abrasion and burial (Okin et al. 2001). Ongoing disturbance could result in complete loss of vegetation cover.
We do not have data for this state, and further research is necessary to describe the community phases and successional pathways that may exist within the state.
