Bobcats and other carnivores can remove over 95% of chronic wasting disease - or CWD - prions from infected meat, according to early findings by Wyoming Game and Fish and researchers at the University of Wyoming.

CWD has spread rapidly across the state - putting deer, elk, and moose populations at risk.

Wyoming Game and Fish Wildlife Veterinarian Samantha Allen said bobcats and other carnivores could be a natural ally in the fight to contain CWD prions.

"It just might be another way to stop some of the transmission, and take some of the CWD off the landscape," said Allen. "Which is really important, and we have a really tough time doing that right now."

While some have warned that carnivores and scavengers help spread CWD prions across landscapes, Allen said that's not exactly what her team is seeing.

Researchers found that just 2% of prions remained in bobcat scat after being fed CWD infected materials. The next day, just 1% remains, and on the third day zero prions remain.

These results are similar to a 2021 study of mountain lions, according to a Wyofile report.

Prions are proteins that can't be destroyed like bacteria or a virus. They remain infectious on the land and can even end up in plants that animals eat.

Allen said the science is mixed on whether chronic wasting disease can be transmitted to people, but advises hunters not to eat contaminated meat.

"My recommendation is to get your animals tested, and to not consume CWD positive material" said Allen. "Because we don't want to push this kind of prion disease to change in a way that it does become more likely that we get infected with CWD."

The challenges of stopping the spread of chronic wasting disease, fatal in all cases except in some moose, are multi-faceted.

Wyoming's winter elk feeding grounds are widely seen as potential super-spreaders. But Allen said if the research is confirmed, carnivores could play an important role in clean up.

"It's not going to be one thing that is going to fix or alter the trajectory of CWD prevalence or even management in some of these populations," said Allen. "It's going to be a lot of different things working together."

Indiana is considering a limited bobcat trapping season and the Department of Natural Resources is seeking public input on the proposal.

The plan would allow trapping in about 40 southern Indiana counties starting in November 2025, with a statewide quota of 250 bobcats. Trappers would have a one-bobcat bag limit and be required to purchase a special bobcat license.

Geriann Albers, furbearer and turkey program leader for the Indiana Department of Natural Resources, said the proposal includes strict monitoring, and requires trappers to report their catches within 24 hours.

"We do have a population model for bobcats," Albers explained. "We're very confident with that 250 quota that it will not negatively impact bobcat populations. What that 250 was set on was the population model we have that shows that's a sustainable level of harvest."

Opponents argued even a limited season could threaten bobcat populations. Environmental groups, including the Humane Society, said the DNR's population model may not fully account for the bobcat's slow reproductive rate and threats from habitat loss. They contended reintroducing trapping could undermine years of conservation work that helped the species recover in Indiana.

Albers noted the DNR invited public feedback on the proposal.

"On that rule-making docket page the comment button is available for people to submit comments now," Albers pointed out. "That went up pretty quickly after the meeting but the first round of comments, we haven't scheduled yet because that usually coincides with when we do a public hearing."

A public hearing, tentatively set for November, will offer both in-person and virtual participation options. The DNR said updates will be posted on its website.

Environmental groups are slamming a Biden administration effort to remove federal protections for the endangered gray wolf.

The U.S. Fish and Wildlife Service just appealed a 2022 court decision reinstating protections for the gray wolf under the Endangered Species Act; protections lost in the Trump era.

Derek Goldman, Northern Rockies senior field representative for the nonprofit Endangered Species Coalition, said federal officials are making contradictory moves.

"On one hand, they said earlier this summer that they want to write a national recovery plan. But then they appealed to reinstate the Trump wolf delisting rule, which would presumably mean they don't have to do a recovery plan," Goldman pointed out. "This is kind of sending a mixed message here."

In the suit, Justice Department attorneys argued the gray wolf is no longer in danger of extinction. The National Rifle Association and hunting and livestock groups also supported the Trump-era policy, which would send protections back to the states.

The California Department of Fish and Wildlife said seven confirmed packs of gray wolves have made their way down from Oregon. Goldman acknowledged the wolves enjoy state-level protections but have a long way to go.

"They certainly haven't recovered throughout all the suitable habitat that's in California, like the Sierra Nevada mountain range," Goldman noted. "But without the resources provided by the Endangered Species Act, they won't fully recover."

The U.S. Fish and Wildlife Service set a deadline of December 2025 to produce a new federal gray wolf recovery plan.

Following the torture of a wolf by a Wyoming man, a state panel is seeking a bill to protect the killing of predators with vehicles, but Federal lawmakers are pushing back.

After Cody Roberts in February hit a gray wolf with his snowmobile, taped its mouth shut and brought the injured animal to a bar, he was fined just $250 and an international outcry followed.

The gray wolf was removed from the federal endangered species list in 2021. In Wyoming, it is considered a "predator" and is legal to kill. The state's newly formed Treatment of Predators Working Group approved a bill, which clarified using vehicles to run over "predators," a practice called "whacking," is legal, as long as all "reasonable efforts to kill" the injured animal are then taken.

Elaine Leslie, retired agency chief of biological resources for the National Park Service, said Wyoming "sanctions this kind of behavior."

"The dialogue during that meeting was focused on, 'Oh, we can't identify or articulate the exact meaning of the word humane or ethical. So let's take that out of the bill,'" Leslie recounted.

In an opposing move, Rep. Nancy Mace, R-S.C., last week introduced a bill to prohibit the intentional use of motor vehicles to harm wildlife on federal lands, establish a protocol for enforcement and penalties and maintain exemptions for human safety.

The bill is co-sponsored by legislators in North Carolina, Florida and Louisiana but notably none in the Mountain West, where the practice of "whacking" coyotes and wolves is legal in several states, as a practice distinct from hunting.

Leslie pointed out the behavior is likely happening elsewhere, too.

"We have no idea what the extent of this behavior is nationally," Leslie acknowledged. "I think it does need to have national attention and be a national bill right now."

A Wyoming legislative committee will hear recommendations from the Treatment of Predators Working Group Sept. 30.
