Correct substitution rates of one grazing animal for another under common use are uniform, being governed at any point by the utilization standard of some single species. This key species may vary at different levels of animal combinations, thus changing the rate of substitution to another but still constant rate. Under certain conditions, common use can add capacity in one direction only, e.g. when the animal to which the range is less suited is substituted for the other. In this case the best suited animal alone provides maximum grazing capacity. The capacity under common use may be greater than that realized with the less suited animal alone, or greater than either animal alone, depending upon the particular combination of animal numbers that are present and the particular range. No blanket statement may be made that common use increases grazing capacity. Each situation must be determined independently upon the basis of animal preferences and the forage present. Administrative problems and social objectives, which were not considered here, may justify allocations of range resources on other bases than grazing capacity. Table 1.
