This book was released on 1981 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheep and lamb losses to predators have been determined since 1958. Predators kill many more lambs than sheep and therefore the upward trend of lamb losses in relation to sheep losses indicates that relative predator losses are increasing. Losses were estimated separately for each of the 33 states that showed definite losses and were then added together for areas and for the United States. The fact that independent estimates of predator losses in National Forest regions showed a high correlation with losses estimated from U.S. Department of Agriculture mortality data helps verify the accuracy of each set of estimates. During the 21-year period from 1958 through 1978, the area of predator damage was enlarged as losses tended to increase both eastward and southward. In general, adult sheep losses were about one third as great as lamb losses in the range states and two thirds as great in the farm states. Total numerical losses of sheep and lambs to predators were 1.5 million head in 1958 and 1.3 million in 1979. The percentage of loss steadily increased from 4.0 in 1958 to 6.8 in 1977, the year of the greatest percentage of loss. Sheep numbers declined during this period, in part because of predator losses. In fact, predator losses appear to have been a major cause of the decline of the sheep industry since 1960. The value of the loss increased fairly steadily from a low of USD25 million in 1961 to a high of USD103 million in 1979, the most recent year statistics were available. All of the eastern states showed relatively minor losses when compared with losses in the western states. Predator losses have had a significant effect on income from sheep. On the average, net income per ewe in 1974 would have increased from USD3.88 to USD8.12 if predator losses could have been eliminated.

Available in PDF, EPUB and Kindle. Book excerpt: Much of the decline of the U.S. sheep industry has been attributed to losses caused by predators. Most predatory losses are inflicted on lambs rather than ewes. Losses have historically ranged from 4-8% of lamb crops, inflicting significant financial loss on ranchers. However, most research providing data on sheep predation is over 20 years old. Changes in the sheep industry as well as predation rates may make previous loss rates inapplicable to current conditions. Coyotes (Canis latrans) are the primary predator of concern when it comes to sheep losses, but increasingly, cougars (Felis concolor) and black bears (Ursus americanus) are reported to be responsible for an increased proportion of lamb losses. I replicated a sheep depredation study conducted during the early 1970s in southwestern Utah and compared the results of the two studies to reassess losses and the predator species responsible for those losses. Total lamb losses to all causes in my study were comparable to losses reported in the 1970s as well as categories of verified and estimated predator losses. There was a significant variation in lamb losses between the 2 years of my study due to an increase in predator kills on sheep. Cougar and bear depredations occurred at significantly higher rates during my study than during the 1970s but did not produce an additive effect to overall predator losses. Most lambs killed by predators were located on or near pasture bed grounds as reported by other studies, but a large number were found>500 m from bed grounds. Rough terrain and scavenging by California condors (Gymnogyps californianus) made location of missing sheep difficult. The ability of cougars and bears to remove sheep carcasses from kill sites made the finding of sheep carcasses more difficult and caused an underreporting of sheep killed by these predators. I found that the loss of sheep to predation continues to be a problem for the sheep industry and its magnitude was unchanged from historic predation levels.
