Changes in Vegetation and Grazing Capacity following Honey Mesquite Control

Abstract
Honey mesquite kill and suppression, vegetation response, as well as changes in grazing use and capacity were evaluated following brush control in north-central Texas [USA]. Tree grubbing was most effective for eliminating honey mesquite, but because of soil and plant damage the treatment did not increase grazing capacity or improve range condition compared to nontreated rangeland. Aerial application of 2,4,5-T + picloram was more effective in killing and defoliating honey mesquite than 2,4,5-T alone, but both treatments significantly increased forage production. The 2,4,5-T + picloram and 2,4,5-T sprays provided a 7-16% increase in grazing capacity over a 4-yr period on light and heavy honey mesquite infested pastures, respectively.
