Description
The floodplain is that portion of the site adjacent to the ephemeral stream channel formed by recurring flooding and alluvial deposition. Sideoats grama and cane bluestem are the dominant grass species. Blue grama also occurs in significant amounts. Apache plume and mariola are the dominant shrubs. Shrubs normally occur in decreasing densities moving away from the channel across the floodplain. Sideoats grama, cane bluestem, plains bristlegrass, green sprangletop and Arizona cottontop decrease under heavy grazing pressure, or from a decrease in available soil moisture, while blue grama, tobosa, and burrograss increase. The amount of rock fragments and/or carbonates in the soil profile, and moderate to low available water capacity contribute to the susceptibility of this site becoming dominated by creosotebush.
