Summary of Methods: This is a scientific opinion paper highlighting the use of prescription grazing as a tool for managing weeds on rangelands.
Article Summary / Main Points:
• Livestock grazing can be used to control in invasive plant by placing the weed at a competitive disadvantage by either modifying the grazing animals behavior, or controlling the timing and frequency of grazing to when the plant is most vulnerable.
• Development of a grazing prescription requires the selection of the right grazer (species, sex, body condition, age, and physiological state), and matching that with the correct season and intensity required for control of the target plant.
• Use of prescription grazing will be limited until it has been proven to be compatible with production goals.
• Like all tools, grazing has its limitations; therefore integrating grazing with other weed control options holds the most potential for the development of a successful weed management strategy.Vegetation Types: All Vegetation Types

Annotation: This paper touches on the many things that have to be considered when using prescription or targeted grazing as a potential tool in weed management, though the specifics on how to apply grazing to a specific site were not touched on. DiTomaso (2000, Weed Science 48:255-265, available in the RSIS database) also presented the idea of integrating grazing and other management options in the development of a weed management plans.
