How Can this Guideline Benefit You? This guideline was designed to provide land managers and ranchers with direct, helpful information on how to best use livestock for managing invasive annual grasses, such as cheatgrass, medusahead and ventenata. In many cases, livestock may be the best tool to manage annual grasses and the goal of this guide is to provide the ecological basis for using livestock to manage invasive grasses and examples of how to use livestock to manage rangelands. Whether you are faced with the threat of invasion by annual grasses, have areas where annual grasses have invaded but desired species are still present, or maybe you are challenged with areas where annual grass monocultures require the site be revegetated or restored, grazing should be a part of your management program. This guide is designed with land managers in mind. What can be the direct benefits of using this guideline? 1) Understanding of the value of grazing as a management tool, 2) Find out how grazing fits into the ecologically-based invasive plant management (EBIPM) system, and 3) Knowledge of the science behind the “Green and Brown” grazing strategy. The “Green and Brown” strategy and EBIPM both take aim at utilizing grazing to stress the undesired plants, such as cheatgrass, medusahead and ventenata (from left to right above) which can help give perennials a competitive edge in growth, seed development, and performance. 4 - How Can this Guideline Benefit You?
Strategic grazing, such as the “Green and Brown” strategy, can provide an energy-efficient, lowcost and effective method of managing invasive annual grasses and other invasive plants. When this grazing strategy can be implemented to manage invasive annual grass infestations, it can heal the land, recover the ecology of the diverse systems and see productivity return in an economical way. phenology between annual and perennial grasses and to provide land managers with an up-to-date and simple strategy for using grazing to manage land where annual grasses are codominant with desired perennial grasses. There are many general discussions about grazing and weeds, but there is no concise, detailed information specifically on grazing annual grass infestations. We developed this guideline based on exploiting the differences in How Can this Guideline Benefit You? - 5
