Description: In this study, we used a modified version of a meta-analysis (compilation and analysis of the literature in which an individual area is subjected to the disturbance and its response is noted) to analyze grazing effects on grassland ecosystems. Prior efforts have focused on one aspect of ecosystem behavior such as productivity or species diversity. In this analysis, we examined several components of ecosystem function that are seldom explored including measures of nutrient cycling and soil compaction. In general, cattle grazing appears to decrease production measures, increase soil compaction, and have mixed impacts on nutrient cycling rates. In studies that examined nutrients, cattle grazing tended to increase amounts of available phosphorus and nitrogen while decreasing the amounts of other nutrients. We located several studies of sheep grazing and found that their impacts are not much different from those of cattle.
