Current and alternative coyote control strategies in the Western United States are evaluated via a computerized simulation model which predicts the economic and socio-environmental impacts of each strategy. A gradual decrease in lamb losses and an increase in net economic benefits are predicted if the 1974 level of coyote control, $7 million, is increased to $20 million. Socio-environmental benefits did not change significantly under that simulation. Beyond the $20 million level of expenditures, net economic benefits are predicted to decline slightly and socio-environmental benefits decline rapidly. At expenditures below 1974 levels, both economic and socio-environmental benefits decline substantially. Changes in mixes of control methods are discovered which permit both economic and socio-environmental benefits to increase. These alternatives include increased use of the M-44 and aerial gunning and decreased use of traps.
