As far as any adjustments to feeding, we will continue to start feeding as late as possible and end feeding as soon as possible to shorten the feeding season or not feed at all where possible. He pointed to a map provided by Game and Fish that showed where the CWD elk north of Dubois was killed. Privacy Policy | Terms of Service | About Us | Contact Us As thousands of elk congregate into the Jackson Valley each winter, their concentrated living conditions raise the risk of disease spreading throughout the herd. Once an elk, deer or moose is infected, it can take around 16 months for the animal to appear ill, though it is still shedding prions and potentially getting shot and eaten by hunters if they don’t have it tested for disease. Where would the elk go? “It really underscores the importance of the, Contract workers with the Wyoming Game and Fish Department distribute rations of hay to elk at the state-run Patrol Cabin feed ground in the Gros Ventre River drainage north of Jackson, Wyoming and east of the National Elk Refuge and Grand Teton National Park. There is also no evidence the practice is likely to increase harvest sufficiently to overcome the negative effects of those increases by disease transmission” if and when animal mortality outpaces reproduction in a population. Baltimore (MD): The John Hopkins University Press. With an elk testing CWD-positive in the Jackson Elk Herd, and many of its animals wintering on the Elk Refuge, the Elk Refuge immediately started adhering to its “Disease Response Strategy” that is 19 pages long, Refuge Manager Frank Durbian told, The Elk Refuge, in response to court action brought by the environmental law firm EarthJustice and conservation groups it represents, has been actively engaged in what it calls a “step-down” plan to wean elk off alfalfa pellets and hay over a course of years. “Unfortunately, CWD has since been documented throughout most of the state, with many mule deer and white-tailed deer herds now exhibiting CWD prevalence levels high enough to potentially impact population performance. Perhaps the closest thing to a mea culpa for inaction coming from Wyoming is this passage in its CWD plan, which people like Roffe, Reiswig, Smith and others agree with. and some weigh around 40 pounds (18 kg). You can view. Prion uptake in plants is being studied at the USGS National Wildlife Health Center. A Yellowstone wolf. In its CWD plan, Wyoming Game and Fish recommends consideration of CWD suppression strategies utilizing an adaptive management framework developed by the Western Association of Fish and Wildlife Agencies (WAFWA) comprised of state and federal wildlife agencies. The current supplemental feeding regime will exacerbate the effects of CWD on the Jackson Elk Herd because elk density at NER far exceeds elk density reported at Rocky Mountain National Park, which was the source of the annual infection rate used in the model.”, Elk are fed on the same 5,000 acres of [the National Elk Refuge] each year, and “given the persistence of CWD prions in the environment, these areas will likely become heavily contaminated with the CWD prion over time if status quo management continues. “At that point, the response will be not asking what we should be doing, but who is going to take the blame?”. The need to develop proven methods to manage CWD is now readily apparent, and doing nothing to combat this disease is no longer acceptable, a sentiment strongly echoed within hunter survey data.”, Connie Wilbert, state chapter director for the Sierra Club in Wyoming, one of the groups that sued to compel the Elk Refuge to halt feeding says, “There is no time to waste. Retired wildlife biologist Smith, who wrote a critically-acclaimed book about elk feeding and the menace of CWD. Keeping more elk alive provides more wapiti available for clients to hunt. Barry Reiswig, former chief Elk Refuge manager now retired, says the moment is rapidly approaching when Wyoming’s willingness to deal with the feedgrounds in a rational, science-based way becomes too little, too late. On August 10, 1912, Congress set aside $50,000 to buy lands and establish a National Elk Refuge north of Jackson. A similar strain is found in cattle and is commonly known as mad-cow-disease (bovine spongiform encephalopathy).

The Triangle X Ranch operates three hunting camps in the Teton Wilderness region of the Jackson Hole, Wyoming directly south of Yellowstone National Park. Elk (Cervus elaphus) are the most abundant large mammal found in Yellowstone; paleontological evidence confirms their continuous presence for at least 1,000 years.Yellowstone National Park was established in 1872, when market hunting of all large grazing animals was rampant. They cannot be destroyed simply by cooking meat at higher temperatures. “We continue to be concerned about the steady progression of CWD westward across Wyoming and of course this CWD-positive elk in close proximity to elk feedgrounds is of particular concern,” he said. “Unfortunately the U.S. With the money that was left over from the land purchase, managers bought supplemental feed for elk. Share this article share ... A great white shark nicknamed Deep Blue is considered by many to be the … An outbreak of CWD that begins in Jackson Hole is not going to stay confined to Jackson Hole, epidemiologists say. Over 15,000 elks can be found in the park. The overture was ignored. As a result, it created an unnatural massing of elk in the high-elevation valley that previously did not exist prior to the arrival of white homesteaders. “Regardless, endemic CWD will likely depress some cervid populations at an unknown but potentially significant level. If a disease infected the Yellowstone elk population, it could negatively affect many other species that are dependent on the elk. "The Refuge can hardly provide such a sanctuary if, every winter, elk and bison are drawn by the siren song of human-provided food to what becomes, through the act of gathering, a miasmic zone of life-threatening diseases.”. “It indicates that the disease is likely in elk that range from the Bighorn Basin through the Absaroka Mountains, into the Jackson Hole area.

Healthy ungulate herds are the basis for the tradition and economy of hunting. ©1986 Panda Symbol WWF “As far as what happens next, we are really encouraged by the early participation and feedback we've gotten so far in the feedgrounds public collaborative process. Additionally, the studies of collared elk by the partners of the Wyoming Migration Initiative and Montana’s wildlife managers, in their excellent maps of elk movements throughout the Greater Yellowstone Ecosystem, show that all Greater Yellowstone elk herds mingle over time.”, Coupled with the specter of environmental contamination occurring at the Elk Refuge and Wyoming’s 22 feedgrounds,  there are. “Mr. Reiswig, Smith, and other Elk Refuge managers refused to be muzzled. “The best ideas for managing CWD and elk in western Wyoming” have actually been known and touted for a quarter century—and that’s phasing out feeding, he said. The elk herd that resides in the northern part of Yellowstone National Park and the southern end of Montana’s Paradise Valley is growing, according to a new count conducted by The impacts on elk numbers in Yellowstone were initially quite dramatic. Authors of the AFWA also refute Wyoming’s argument. Now, in more ecologically-enlightened times, this management practice is highly controversial. - Yes, they’ve been carrying out a public process, a series of events called ‘listening sessions’. While the establishment of the NER undoubtedly contributed to the preservation of a species that was on the brink of catastrophe, the NER’s feeding program is now rapidly trying to phase out. This, then, raises a question: how could thousands of acres encompassing feedgrounds and the Elk Refuge be decontaminated in a way that renders prions inactive and unlikely to infect elk and deer year after year? Yet bewildering to conservationists is that while some agencies have written general plans for responding to CWD, there is not yet a single uniform strategy for addressing CWD in a way that recognizes elk and deer moving in long distance migrations, across the lines of three different states, 20 different counties and a mosaic of federal, state and private land. Elk - Yellowstone National Park (U.S. National Park Service) “Based on research that grass plants can bind, retain, uptake, and transport prions, the potential prion transmission risk of contaminated hay harvested from the CWD endemic area being fed at state elk feedgrounds should be considered,” authors of Wyoming’s CWD plan note. Led by world-class naturalist guides, our eco-conscious expeditions take you to the world's most remarkable nature locales.

Roffe scoffs at this, noting that there probably won’t be any overt clinical signs of CWD in many affected animals and that by the time an animal looks sick, transmission of prion contagions to other animals has already happened. The elk (Cervus canadensis) or wapiti is one of the largest species within the deer family, Cervidae , and one of the largest terrestrial mammals in North America, as well as Central and Northeast Asia . What’s noteworthy is this: At the National Elk Refuge there are ten times more elk than at Rocky Mountain Park, they are clustered together in much smaller areas than at Rocky Mountain and they are on feedlots which is not the case at Rocky Mountain. The prions can continue to alter the brain without any resistance. In places like the lower Ruby River corridor in southwest Montana where the infection of rate of white-tailed deer tested. The Northern Yellowstone elk herd, one of the most famous and closely watched in the world, is finally growing at a healthy clip. What if there were fewer elk and they weren't fed? “Surveillance for the majority of these populations is difficult because they are widely distributed in high mountain habitats during summer and winter at lower elevations outside the park,” authors of Yellowstone CWD Surveillance Strategy add. Most worrisome to infectious disease authorities is that Grand Teton Park, where Jackson Hole CWD Elk Case No. After decades of debate over whether this range was overgrazed by too many elk, some concern has shifted to the herd’s small size. We may be better off than trying to initiate or use too much science to manage maybe what science shouldn’t be doing that.”, Apparently lost on Taylor was that letting animals kind of do their thing would mean not feeding elk. The NER is truly a refuge for this migratory species. Let the animals kind of do their thing. If an area becomes contaminated, it will continue to harbor infectious agents for a substantial amount of time and may spread indirectly to other animals visiting the area.

Following an outbreak of CWD in white-tailed deer in southwest Montana along the lower Ruby River, the Montana Fish and Wildlife Commission has enlisted hunters to aggressively reduce the number of deer. With the first case of Chronic Wasting Disease in a Jackson Hole elk confirmed in nearby Grand Teton National Park, wildlife officials worry about the deadly disease spreading to animals at the Elk Refuge. But it is not merely a local concern. He predicts Wyoming will fight those possibilities until it can no longer deny the facts. Following her departure, Wyoming in July 2020 released an updated CWD Management Plan and offered this assessment of the toll CWD is likely to take. All TSE variations are contagious and fatal to animals that become infected. “Prior to hay being purchased and transported to elk feedgrounds, the [Wyoming Game and Fish] Department will consider the spatial and temporal relationships between the location of potential source hay fields and the prevalence and distribution of CWD in cervids in these areas. As competition between Jackson residents and wildlife persisted, the region’s elk population began to dwindle. An elk taken by a Montana bowhunter this past season was the largest ever taken in the state and the largest recorded in the U.S. in 48 years — and it could yet turn out to be a world record. Key to slowing the proliferation of any disease is some semblance of contact tracing, so that epidemiologists can get a handle on the source of hot spots and whether different strains are emerging. Federal and state feeding programs for elk and deer are excellent ways of spreading the disease quickly and with devastating efficiency. Reiswig agrees, saying he experienced it firsthand.

Current research reveals the dangers of manipulative wildlife management and surplus feeding, and the issues have no clear solution. After years of continuous warnings from a chorus of wildlife disease experts, government whistleblowers and conservationists, the bad news no one wanted to receive has arrived: Chronic Wasting Disease has reached wild elk in the geographic heart of the Greater Yellowstone Ecosystem. Hence, that’s what scientists mean by potential superspreading. Earlier in the fall, tourists in Wyoming got to see the unique sight of a grizzly bear taking down an elk in Yellowstone. Elk, also called wapiti, experienced a vast reduction of its historic range. Back in the late 1990s, the Clinton Administration was poised to support the gradual phase out of feeding.

In a study produced by Yellowstone National Park, biologists determined that elk make up approximately ninety percent of winter wolf (Canis lupus) kills and are an important food for grizzly and black bears (Ursus arctos, Ursus americanus), mountain lions (Puma concolor), and at least twelve scavenger species, including coyotes (Canis latrans), ravens (Corvus corax) and bald eagles (Haliaeetus leucocephalus). In the fenced bottleneck of the NER, one infected animal could transmit a fatal disease to the rest of the herd, creating a dire circumstance for the Greater Yellowstone Ecosystem, of which elk are considered a keystone species. “Wildlife on National Wildlife Refuges and National Park lands in the US is a public trust managed for the benefit of all citizens, not just a few, and not just the state of Wyoming,” Roffe wrote. CWD infectious agents are resistant to chemical and environmental degradation. Many indicate exactly the opposite. Indeed, as illustrated in this map from the Wyoming Migration Initiative, elk from Jackson Hole stream into Yellowstone during summer where they come in contact with other herds that disperse widely across the three-state region. 1 represents the start of a troubling new era for big game herds in America’s most iconic wildlife-rich region or possibly something much worse, the most stunning reality is that CWD is present among the most famous, migratory elk and deer herds on the continent. Diseased animals ultimately lose their motor skills and eventually waste away and die from the degeneration of the central nervous system. Prior to Euro-American expansion across the continent, elk herds numbered in the millions, but by the late 1800s, they were reduced to approximately 50,000. Both groups claim that stopping or drawing down feeding would result in a massive die-off of elk—an assertion that has never been tested nor is there compelling research to suggest it’s true.

At first light this morning I pulled over noting a Bull Elk with a few cows in the upper right of the meadow depicted in the opening photograph. “Heaven help us if a human ever catches a case of CWD or if the number of CWD cases explodes in Wyoming in our region,” he said. On January 20, 2017, only weeks after the CWD forum was held in Jackson Hole, Eric Cole, a longtime Elk Refuge senior biologist, delivered a corroborating shot across the bow. Guilford (CT): Lyons Press. “Our sampling here is robust,” Durbian said. “One basic epidemiological principle serves as the foundation for a response to CWD at the National Elk Refuge: Limit transmission of prions to susceptible animals and limit contamination of new geographic areas to the greatest extent possible,” the document reads. About 800 moose inhabit the southern part of Yellowstone, Grand Teton National Park and surrounding national forests. ®WWF and World Wildlife Fund are WWF Registered Trademarks. “Where possible, elk feeders [will] work to expand their feeding areas in order to feed on clean snow and new areas to increase the opportunity for elk to feed on areas with less biological contamination each day. Part of the park's CWD surveillance plan is identifying animals that appear ill or in physical distress. Notably, the WAFWA’s national governing body, the Association of Fish and Wildlife Agencies, recently issued a technical report identifying the best management practices for confronting CWD. Hoffman knew what we were proposing to do and when we were together he said, ‘Not going to happen.’”. Get your free copy of our catalog of The World’s Greatest Nature Journeys! This can lead to exposure to larger doses of infectious agents, multiple exposures, or exposures sustained over prolonged periods of time all resulting in greater probability of infection. In November 2018, Chronic Wasting Disease (CWD), an incurable affliction that infects all species of North American deer, manifested itself near Jackson, WY. At that meeting, Rocky Mountain National Park was cited as a reference point. Using Smith’s figures, wolves residing primarily in Yellowstone kill between 1,568 and 2,156 elk annually. “It is incumbent upon wildlife managers to explore ways to manage CWD prevalence and contribute to the broader understanding of effective CWD management. Some biologists observe that traditional winter-feeding of wild elk has generated a habitual dependency on the Jackson Valley. I love seeing the elk in Yellowstone and the herds of bison and hearing the sounds they make. "Thus, our disease management objectives will focus on early detection and monitoring. 2nd ed.
