Vegetation change was evaluated for 4 years following aerial application of 2,4,5-T + picloram (1:1) at 0.56 kg/ha to semiarid rangeland with a light canopy cover of honey mesquite (12%) and sand sagebrush (2%). Stand reductions of woody plants exceeded 95% at 4 years after treatment whether in grazed or ungrazed pastures. Forage production increased on areas with brush control and protection from grazing only in years of average or above-average rainfall. However, sprayed, ungrazed areas produced during the study period an average of 3 kg/ha/year more grass for each centimeter of precipitation received than did untreated, ungrazed areas. At the end of the study, areas sprayed and protected from grazing supported more grasses of fair to good grazing value than did unsprayed areas.
