Abstract
Though accounting for less than 1 percent of U.S. livestock industry receipts, sheep and goat operations are still important to the economies of several states in the Southern Plains, Mountain States and Pacific regions. Revenues from sales of lambs and culled ewes amount to more than three-fourths of the total receipts in the sheep industry. However, nearly 4 percent of the animals in the sheep industry are lost each year. Most of this loss is from predation. Predators include coyotes, domestic dogs, big cats, foxes and bears, and eagles. Predator losses are concentrated in the Southern Plains, Pacific States and Mountain regions, due to a high concentration of both sheep and predators in these regions.
Most previous studies have looked at the direct loss from predation. We used the Impact Analysis for Planning (IMPLAN) procedure to construct an input-output (I-O) model of the 10 USDA farm production regions to look at some of the indirect effects associated with predation. The direct value of all sheep and lambs lost due to predation for 1999 was simulated using this I-O model and the regional economic impact evaluated. The simulated impact of predator losses on the U.S. sheep industry showed that a $16 million direct loss in sheep and lambs due to predation results in a more than $12 million additional income loss over the rest of the economy. The economies of the Mountain States, Southern Plains and Pacific were most affected.
