As a whole, grasshopper densities were greater on ungrazed sites compared to grazed sites. Melanoplus sanguinipes and all species of Melanoplinae were greater on ungrazed sites, while Oedipodinae species were greater on grazed sites. Gomphocerinae species were not influenced by grazing. Total density and species composition of grasshoppers were impacted by grazing. This study suggests that grasshopper populations are negatively effected by livestock grazing during drought conditions in the area.
