A FORTRAN IV model of the inter- and intra-seasonal energy flow through deer populations was developed for evaluating the potential biological productivity ofland for deer. The productivity per unit cost is suggested as a means for evaluating land being considered for acquisition for deer management areas. The model uses the "Standard Deer Unit," an integration of climatic, behavior, and other factors. To characterize the energy dynamics of deer maintenance and production subjective probability estimations are made by the user of successional changes in cover and forage production. Indices of the potential sightable and harvestable deer production are calculated in standard deer units at 5-year intervals over a SO-year planning horizon.
