Title: Habitat selection by the Texas tortoise in a managed thornscrub ecosystem: Journal: Journal of Wildlife Management; Authors: R. T. Kazmaier, E. C. Hellgren, and D. C. Ruthven; Date: 2001; Summary: Kazmaier et al. looked at the effects of cattle grazing on the habitat selection of the Texas tortoise. Tortoises preferred areas of multiple canopy layers of woody brush, while avoiding riparian areas and old-fields (grasslands). Riparian areas lacked herbaceous vegetation and were higher in predators. Old fields, or grasslands, were avoided due to lack of mobility with the increase of grass and the lack of canopy cover. However, the authors conclude that mechanical means of converting shrublands into grasslands for increased cattle forage would have little effect on the Texas tortoise be ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Animals for biological brush control: Journal: Agronomy Journal; Authors: G. M. Wood; Date: 1987; Summary: Effectiveness of cattle, sheep and goat grazing to control undesirable shrub species was examined in a 4 year study in West Enosburg, VT. Cover density was estimated by analyzing photographs taken on a transect line in pastures grazed by sheep, cattle and goats to determine their effectiveness as a potential biological control in brush infested land in the northeastern US. Stocking rate for each paddock was 100 kg of metabolic weight per 0.4 ha (2 cows, 8 sheep and 8 goats). Plots were grazed from mid-June to mid-October. Photos were taken before and after grazing. ...; Agrovoc Control Words: Shrubs, Rangelands, Grazing; View more details about this article
