L.  aPattern of retrogression of native vegetation in North Central Oklahoma.h[electronic resource]  c1965  aAbstract: The pattern of retrogression due to grazing for native vegetation was established for the important plants of the loamy prairie range site. Total forb numbers increased as range condition declined but there were usually as many perennial forbs in high condition pastures as in low condition ones. Total available water was significantly greater in excellent condition than poor condition range.  aRange management  aConservação  aErosão  aSolo1 aDWYER, D.
