John Walker, Texas Ag Experiment Station resident director of research at San Angelo, has co-authored “Targeted Grazing: A Natural Approach to Vegetation Management and Landscape Enhancement.”

The first six chapters outline basic principles of animal and plant interactions in targeted grazing. The second section examines management applications used to control broadleaf weeds, invasive grasses and noxious brush. The last three chapters look at targeted grazing from different perspectives and offer additional resources, a glossary and photos.
