Summary of Methods: The bio-economic model used in this study found that grazing cattle (Bos taurus), in a system featuring two years of non-use and one year of use between June and late September, led to an increase of 14.6% in the potential carrying capacity of mule deer (Odocoileus hemionus) summer range. The loss from reduced livestock production, which was required to increase deer hunting value, was greatly exceeded by the net economic value gain of hunting. This model proved to be helpful for multiple use land managers in finding the most beneficial land management strategy.

Annotation: Three different grazing systems were used. The first system was 2 years of non-use by cattle followed by 1 year of moderate grazing. The second system was 1 year of non-use followed by 2 years of moderate grazing. The third system was 1 year of non-use followed by 2 years of heavy grazing. Moderate grazing is defined as 0.71 AUM/ha and heavy grazing as 1.33 AUM/ha.
