Wilkin School of Renewable Natural Resources, College of Agriculture, University of Arizona One of the principal mechanisms operating in any grazing management program is the differential utilization of forage species. An ability to predict this differential utilization pattern and diet, prior to the application of a grazing program, would allow more accurate prejudgment of the program's expected success. A predicting scheme is discussed, along with an actual application of this scheme to prediction of utilization of forage species and diet by sheep on Utah winter range. S. S. Hutchings and G.
