One of the weakest phases in range management is the failure of field men to evaluate current degree of use in relation to that which may be considered proper. This weakness is due largely to the lack of confidence of field men in their ability to determine percentage utilization of forage species on ranges grazed by livestock. This article sets up results of utilization estimates made by average field men with moderate training and shows the accuracy with which degree of use of range grasses can be determined by using a simple field technique. The application of this study to everyday range inspection should be of interest to all actively engaged in range-management work.
