Title: Slow recovery in desert perennial vegetation following prolonged human disturbance: Journal: Journal of Vegetation Science; Authors: Q. Guo; Date: 2004; Summary: Guo determined the long-term recovery of a Sonoran Desert plant community from historical human and livestock disturbances, using current and historic data sets. Since the removal of livestock from the Desert Laboratory in 1907 there has been a large increase in plant cover and species richness which is composed of increases in cacti, herbs, and half shrubs while no invasive species were found on the site. Plant community dynamics were similar in all plots in 1907 and since have diverged into unique plant communities, however, community dynamics are still not related to climactic changes and ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Winter sheep grazing in the irrigated Sonoran Desert: II. Soil properties and alfalfa regrowth: Journal: Journal of Production Agriculture; Authors: A. R. Mitchell, J. N. Guerrero, and V. L. Marble; Date: 1991; Summary: Mitchell et al. conducted a two-year lamb grazing trial, at the University of California Imperial Valley Research and Extension Center near El Centro, California, to test the effects of lamb grazing by measuring alfalfa (Medicago sativa) yield for the first harvest following grazing, and the soil parameters of penetration resistance and infiltration rate. Authors used a severe degree of grazing, after 600 hd d/acre, only bare ground and grazed alfalfa crowns remained. Despite this severity, yields were 5.4% greater at the first spring cutting in comparison to mowed, ungr ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
