Description
This state represents the most ecologically stable conditions in terms of resistance to erosion. Moreover, this state has the highest potential for productivity and plant diversity.
Submodel
Description
This state is characterized by decreased available soil moisture. Typically galleta or blue grama is the dominant grass species. Alkali sacaton if present is generally found in clumps or tussocks with interconnected bare areas between plants, or in patches on wetter low spots.
Submodel
Description
This state is characterized by the predominance of shrubs, especially rabbitbrush. Spineless horsebrush and broom snakeweed may also increase in representation. Blue grama, galleta, and alkali sacaton are typically the dominant grass species, however, alkali sacaton may be sparse if the transition to this state was from the Dry Grassland.
Submodel
Description
Bare State: Extensive areas of bare ground characterize this site. Surface soils in most bare areas are sealed over with physical crusts. Herbaceous cover consists mainly of annuals. If perennial grasses are present they occur only in isolated patches.
