Description
This State represents what is believed to show the natural range of variability that dominated the dynamics of the ecological site prior to European settlement. This site, in Reference, is dominated by salt-tolerant warm- and cool-season grasses, forbs, and shrubs. As grazing pressure and hoof action increases, the resulting soil compaction will cause salts to accumulate closer to the soil surface and inland saltgrass will increase. Greasewood will also increase on the western side of the MLRA.
Submodel
Description
Heavy, long-term animal impacts have altered soil site stability, hydrologic function, and the biotic integrity of the site. Salt accumulation near or at the soil surface has reduced the vigor of many of the species present in the Reference State (1.0). This State is resistant to change and a restoration pathway may not be feasible.
Submodel
Mechanism
Heavy, continuous grazing, excessive haying with no recovery opportunity or heavy disturbance will shift this plant community to the Inland Saltgrass Sod Plant Community (2.1).
