Studies Show Effectiveness of Targeted Grazing

Researchers at University of Minnesota’s College of Veterinary Medicine and the College of Food, Agricultural and Natural Resource Sciences synthesized results of 70 individual studies to assess the effectiveness of targeted grazing, which is an increasingly popular land-management tool. They found that targeted grazing was effective because it significantly reduced the abundance of the undesired plants that the livestock were brought in to control. They also found that the number of plant species in grazed areas tended to increase, although studies weren’t clear about whether these increases were in native or non-native species. The researchers say there is also a knowledge gap in the long-term effects of targeted grazing once the livestock are removed from the site, which should be addressed by future studies.
