AbstractTen sheep ranches in southwestern Utah were chosen for a verification study of sheep losses during 1972-1975. Using the ratio of verified predator kills to total lamb carcasses discovered, total lamb loss to predators was estimated. Predation accounted for 5.8% of total lambs docked or 62% of the total lamb loss. Coyotes made 94% of all predator kills. For the 10 herds (1972-1974) direct income loss due to lamb predation averaged $2,800 per herd; for a three-herd subsample (1972-1975) direct income loss averaged $3,500 per herd. Applying our study rate of predation to the entire Southwest region of Utah gave an estimate of 14,900 lambs killed by predators and a direct income loss of $419,000. In addition, the region suffered indirect or multiplier losses of $1,166,000 to $1,816,000 during the 4 years studied. Further data needs in predation economics could be achieved by integrating predation loss, predator population, and predator control data into a standard production function model.
