Title: Vegetation response to the Santa Rita grazing system
Journal: Journal of Range Management
Authors: S. C. Martin, and D. E. Ward
Date: 1988
Summary: Changes in vegetation under yearlong grazing were compared with those under Santa Rita grazing system, a rotation system designed for southwestern US rangelands where 90% of the forage is produced in mid-to late-summer. The study was conducted in Arizona from 1972 to 1984. In 1984 there were no significant differences in grass densities, forb densities, shrub densities, or shrub cover on pastures grazed yearlong or in the Santa Rita rotation. The authors attribute annual variation in grass species densities to precipitation, which reduced shallow-rooted species in gravelly and sandy soils w ...
