Even with the use of single or combined nonlethal methods, livestock losses to predators often continue.”. Treves wants the findings to prompt governments and hunters to stop shooting, trapping, and using other methods to kill “problem” predators until better science becomes available. It is understandable for struggling ranchers to blame coyotes for economic losses, since kills leave tangible signs and killing predators seems like a logical solution. But these killings might not solve any problems after all. This means that we need to choose prevention and mitigation methods carefully. In 2010 predators killed 220,000 cattle and calves in the United States. However, many of these methods are implemented without first considering experimental evidence of their effectiveness in mitigating predation‐related threats or avoiding ecological degradation. 2020 National Geographic Partners, LLC. “People deserve to hear the options and understand the evidence, especially if our government claims to be science-based in our policies,” Treves says.

Some studies looked at whether killing predators meant fewer livestock deaths, while others examined the success of nonlethal deterrents, such as the use of guard dogs and flag-lined ropes or wires. What are my options? Animal and Plant Health Inspection Service, Fruits and Vegetables Import Requirements (FAVIR), http://digitalcommons.unl.edu/icwdmhandbook/. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, killed more than 1,100 domestic dogs between 2000 and 2012, unintentionally killing numerous animals and birds, overprescribing antibiotics to human patients, Deliberate Efforts to Achieve Herd Immunity to COVID Are Dangerous, Restoring Seagrass Brings Barren Bays To Life, A Brief History of Presidents Disclosing--Or Trying to Hide--Health Problems. A State office can be reached by dialing toll free 1-866-4USDA-WS (1-866-487-3297).

"Lethal methods tend to be more risky for livestock and therefore for livestock owners than nonlethal methods," Treves says. These findings extend beyond the United States. This story was produced by National Geographic’s Special Investigations Unit, which focuses on wildlife crime and is made possible by grants from the BAND Foundation and the Woodtiger Fund. And farmers and ranchers often act based on deeply rooted traditions and cultural attitudes. Patients often demand antibiotics for common colds, although doctors understand that these infections are caused mainly by viruses, so antibiotics will be ineffective. The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Read more stories from the SIU on Wildlife Watch. Other research indicates that even if predation is one factor in ranchers’ economic losses, lethal control is not the best way to reduce it. Predators including coyotes, wolves, foxes, mountain lions, grizzlies, and eagles play vital roles in our ecosystems, and their presence among people creates opportunities and challenges. All rights reserved. But receiving a prescription makes patients feel that their concerns are being addressed. As for the studies that did evaluate the effectiveness of lethal predator control, seven used shoddier science but were reliable enough to “draw an inference about,” Treves says.

Pelts from four gray wolves shot by United States federal officials in Montana hang over a truck. Even research by USDA supports this pattern. Nonetheless, their range has expanded from the western plains across most of the continent. Wolves killed this Montana rancher's calf. There has been significant interest in using livestock guard animals, sometimes also referred to as predator control animals or mobile flock protectors, as a non-lethal means of reducing predation. Killing predators such as wolves, mountain lions and bears to protect livestock may have intuitive appeal, but a review of multiple studies published Friday shows little or no scientific support RESEARCH ARTICLE Killing wolves to prevent predation on livestock may protect one farm but harm neighbors Francisco J.

External review would be useful because even experienced ranchers may have trouble determining in some cases whether a sheep was killed by a coyote or a dog (dogs are second only to coyotes in reported predation on livestock), or died from other causes and later was scavenged by coyotes.

As in warfare, there is collateral damage. The United States used this justification to kill thousands of coyotes, wolves, bears, and other predators last year. For detailed information about the biology and ecology of predators, as well as predation management information for various predator species, the handbook entitled, “Prevention and Control of Wildlife Damage” is available online. In a recent case study at a cattle station, researchers found that ceasing all lethal and nonlethal predator control reduced predation of cattle by dingoes as the social structure of the resident dingoes stabilized. Nonlethal methods included fladry, guard animals, chemical repellents and livestock protection collars. At the same time, research shows that predators play key roles in maintaining healthy ecosystems. Wildlife Watch. This article was originally published on The Conversation. Predators may provide recreational benefits via observation and photography, and yet they may pose challenges for ranching operations.

Instead the papers concluded that certain nonlethal predator-control methods helped ward off future attacks on livestock. A new study found that there’s little evidence that lethal predator control does anything to help ranchers.
