Summary of Methods: Saiwana et al. suggest that scaled quail (Callipepla squamata) abundance in the Chihuahuan Desert could be maximized with a mixture of late-seral and mid-seral plant communities. Vegetation structure and composition should be maximized. This objective could be obtained by livestock grazing that removes 30% of the current year's growth of the key forage species; mesa dropseed (Sporobolus flexuosus), black grama (Bouteloua eriopoda), and threeawn. Sites in late-seral and climax ecological conditions may benefit from grazing, while grazing on early-seral conditions may negatively effect scaled quail food and cover.

Annotation: The Chihuahuan Desert Rangeland Research Center (CDRRC) site had a utilization rate of 30% for the key forage species and the BLM had a 20-40% utilization rate from 1982 to 1990. Between 1986 and 1990 the CDRRC had a stocking rate of 48 ha/AU and the BLM had a stocking rate of 67 ha/AU. A continuous grazing system had been used on the BLM. On the CDRRC land, 45% was continuously grazed and 55% was grazed under a best pasture grazing system.
