the results <strong>of</strong> analytic evaluations <strong>of</strong> animal population dynamic;
(modeling) based upon actual bait consumption <strong>of</strong> 1080 large-baits at
640 sites for which data was available in Wyoming during the 1976-77
period. The analyses were performed under a contract with the Animal
Plant Health Inspection Service (APHIS) <strong>of</strong> the USDA. Expected sheep
and lamb loss reduction in Yyorning was computed by aggregating
