Description
With continuous grazing, palatable perennial grasses like plains lovegrass, blue, black and sideoats grama decrease and species like tobosa and curly mesquite increase. Severe drought can reduce short grasses to very low levels. Drought - fire combinations can reduce perennial grass cover and allow annual herbs to become dominant for a short time (2-4 years) until grasses can recover. Due to heavy surface soil textures, this site can be a inefficient user of intense summer rainfall when the perennial grass cover has been removed or greatly reduced. Mesquite, when present on the site, tends to be shrubby due to the presence of clay horizons at shallow depths.
