Grizzlies killed record high number of cattle in Wyoming, 2024 data shows – WyoFile
Every year is a conflict-prone year for the scores of cattle and grizzly bears that mix annually on Union Pass, but Coke Landers was especially glad to put 2024 behind him.
The run-ins started shortly after the historic Green River Drift delivered many thousands of cattle to the national forest to fatten up over the summer. By the time ranchers herded the domestic bovids off the vast 267-square-mile Upper Green River grazing allotment on the Bridger-Teton National Forest in the fall, some 94 head of cattle were confirmed to have been killed by large carnivores, he said.
“Ninety-one of them were bears and three were wolves,” said Landers, who took the reins of the Upper Green River Cattlemen’s Association from former president Albert Sommers a few years ago.
“That was the highest ever,” Landers said. “It was a record.”
That’s especially notable considering that the Upper Green has been the Greater Yellowstone Ecosystem’s epicenter of grizzly-cattle conflict over the last couple of decades. It’s also been the site of a not-yet completely resolved legal battle about that conflict, stemming from a federal assessment that OK’d killing up to 72 Endangered Species Act-protected grizzlies due to cattle grazing on public land.
Across grizzly range in the Equality State, it was a tough year for not only bruins killing cattle but for conflict generally. Grizzlies, in turn, were killed at record rates.
The phenomenon was partially explained by the dry year, which 2024 certainly was: More than 800,000 acres in Wyoming burned. The result is desiccated vegetation and sparse berry crops that send the adaptable omnivores looking for alternative food sources. Oftentimes, they end up finding trouble instead.
Wyoming Game and Fish Department officials ran through the numbers and nature of the conflicts during their commission meeting last week in Cody.
“They’re occurring on private lands, the majority of these conflicts,” said Brian Debolt, the large carnivore conflict coordinator for Game and Fish.
Grizzly bears have stopped expanding their range in the Greater Yellowstone Ecosystem, federal biologists say. Nevertheless, much of where they occur today is outside of what Wyoming officials believe to be “suitable habitat.”
“The amount of private land occupied by grizzly bears in the Yellowstone ecosystem — outside of suitable habitat — is bigger than the area of New Jersey,” Debolt said. “Frankly, I get frustrated.”
A graph Debolt presented showed that upwards of 60% of all verified grizzly conflicts in 2024 occurred on private property.

Another graph broke down the cause of the conflict. Cattle dominated with 188 of 242 — a whopping 78% — of all confirmed Wyoming grizzly bear conflicts attributed to domestic bovids in 2024. In order, the next largest conflict sources were pet food, livestock feed and birdseed (13 conflicts) and property damage (11 conflicts).
Grizzlies also killed a record number of Wyoming cattle, Game and Fish Large Carnivore Supervisor Dan Thompson told WyoFile.
“It’s definitely our highest level of conflict,” Thompson said. “There’s this notion that nobody’s doing anything about it. That’s not true. Those producers are doing as much as they can to reduce that conflict potential — as are we.”
About half of Wyoming’s grizzly depredations in 2024 occurred in the Upper Green. Four grizzlies there were captured and killed in response, Thompson said.

There’s been mixed results from efforts to stem the grizzly bear-cattle bloodshed on the massive Bridger-Teton National Forest allotment. Nearly a decade ago, range riders attempted an experimental herding technique to keep cattle bunched up and less vulnerable.
“The herding actually made the kills worse,” Landers said.
More recently, the Upper Green River Cattlemen’s Association tested out motion-triggered LED lights known as “flasher tags” that were fastened to calves’ ears.
“I put 250 in, and I didn’t have any calves killed with a flasher tag that year,” Landers said. “But when I pulled the flasher tags in the fall, of the 250, there were only 10 of them that were still working.”

Wyoming secured, but then lost, a federal grant that was going to allow Upper Green cattlemen to scale up the effort with more durable flasher tags, according to Thompson. He didn’t specify exactly what happened to the grant, which went away during a period of extreme turmoil for the federal workforce and grants provided by the federal government under the Trump administration.
“There’s a lot of unknowns right now, let’s put it that way,” Thompson said. “But we still figured out a way to do a pilot component to look at some of these things. We’re still moving forward.”
A new prototype of the tags, Landers said, went out on 14 calves during the 2024 grazing season.
“One of my calves with a flasher tag got killed,” Landers said, “but all of those flasher tags were working when they came home.”
In 2025, they’re going to try another design again, just not in big numbers, he said.

A few months out from the Bridger-Teton grazing season, Landers is encouraged by the relatively big snow year in the region. Snowpack readings in the Upper Green River drainage were sitting at 110% of the long-term median as of Tuesday, but a SNOTEL site up in the allotment was at 127%.
“We should have plenty of moisture and hopefully not as dry of a summer,” Landers said. “A better berry crop does make a difference.”
If an easy conflict year doesn’t come to fruition, the status quo will have to do. Although there’s plenty of carnage, the system is one that the Upper Green River Cattlemen’s Association president says is working.
“The way our cattle association has been living with the bears and the wolves — and with our state’s compensation program — is a pretty good success story,” Landers said. “Honestly, we’re living together. We’re not always getting along, but we’re living together and we’re getting it done.”
Grizzlies in Wyoming and throughout the Lower 48 continue to be managed as “threatened” under the Endangered Species Act. A Biden-era proposal to extend that classification, which precludes grizzly bear hunting, is open to public comments through May 16.

Evacuations spread from fires in South Dakota, Wyoming due to strong winds from coast-to-coast storm
CLIMATE TECH: As wildfires grow stronger, faster, and more expensive, a California-based startup is taking a high-tech approach to fight these fires using autonomous drones designed to extinguish flames before they turn deadly. Founder & CEO Stuart Landesberg joins FOX Weather to discuss Seneca’s firefighting drones.
Large, fast-moving fires are causing evacuations in South Dakota and Wyoming due to the impacts of a coast-to-coast storm.
The FOX Forecast Center said winds have been gusting up to 70 mph in the Pennington County, South Dakota area, which has caused the wildfire to spread rapidly.

University of Wyoming sues former energy research partner for $2.5M – WyoFile
The University of Wyoming filed a lawsuit this week seeking $2.5 million from an energy company it partnered with to research enhanced oil recovery.
The university in 2024 signed a contract with Houston-based ACU Energy to advance research at the university’s Center of Innovation for Flow Through Porous Media, according to the university’s complaint filed Monday in Wyoming’s U.S. District Court. ACU Energy agreed to pay the university $15 million over the six-year research period. The company, according to the complaint, was to pay the university $2.5 million annually with two payments each year.
While the university kept up its end of the bargain — by assembling a research team, training research members and incurring costs to modify laboratory space — ACU Energy “failed to pay the University even a cent owed under the Agreement, leaving $2,500,000 outstanding in unpaid invoices,” the complaint alleges.
ACU Energy did not respond to a WyoFile request for comment before publication.
The company notified the university in February that it was terminating the contract, and the university notified ACU Energy in May of its breach of contract, according to court filings. The university asked the court for a jury trial.
Enhanced oil recovery refers to methods used to squeeze more crude from reservoirs that have already been tapped for primary production, extending the life of an oilfield.
The university commonly accepts money from private businesses in return for lending resources and expertise to advance research. The Center of Innovation for Flow Through Porous Media is part of the university’s Research Centers of Excellence in the College of Engineering and Physical Sciences.
The Center of Innovation for Flow Through Porous Media, led by Mohammad Piri, a professor of petroleum engineering, bills itself as “the most advanced oil and gas research facility in the world.” The center conducts research at the university’s High Bay Research facility, which “is funded by $37.2 million in state dollars and $16.3 million in private contributions, with an additional $9.2 million in private gifts for research equipment,” according to the center’s website.
The center has received donations from oil industry heavyweights like ExxonMobil, Halliburton and Baker Hughes.
Piri was tapped to serve as “principal investigator” for the UW-ACU Energy partnership, according to the university’s complaint. As of press time, ACU Energy had not filed a response to the lawsuit.

Search for fugitive wanted for child-sex crimes leaves Wyoming town on alert
With a population under 600, Byron, Wyo., is generally a quiet town. In recent weeks, streets have been even quieter as both local and federal law enforcement search for 39-year-old fugitive Anthony Pease, who is wanted for six counts of sexual assault involving a minor.
Authorities have been searching the area for weeks, and a reward for information leading to an arrest now sits at $2,000.
See how the search impacts the town:
Search for fugitive wanted for child sex crimes leaves Wyoming town on alert
Saturday morning, law enforcement shared there was a confirmed sighting of Pease near town and reminded residents to remain vigilant by locking their doors and reporting suspicious activity. According to Wyoming’s Big Horn County Sheriff’s Office, before the weekend sighting, Pease hasn’t been seen since Nov. 1.
The Big Horn County Schools Superintendent, Matt Davidson, told MTN News a school resource officer on staff stays up to date with the latest on search efforts, and some parents say they’ve been keeping their kids indoors when they’re not at school.
As the search continues, the mayor as well as some residents, say they are taking law enforcement’s advice while keeping a watchful eye.
“I never used to lock my house during the day. I didn’t even lock my vehicles at night. In fact, a lot of the time I’d leave the keys in them. I’ve talked to other people and there is quite a few people that are nervous. I would hope that a lot of us are nervous because this is a bad thing,” said Byron Mayor Allan Clark.
In fact, investigators could be seen around Byron knocking on doors and scanning land outside of town.
“There’s just so much area and a low population, so much area for him to hide and seek shelter,” Clark said.
With so many wide-open spaces and abandoned buildings in the area, Clark understands why the search has gone on so long.
According to the US Marshals Service, Pease is 5 feet 11 inches tall and may also be going by the name Abraham. They also ask that anyone nearby who has a collection of silver dollars to ensure they are still there, and if not, to report to authorities.
Marshals say Pease is considered dangerous, and the public is told to not approach him and instead call 9-1-1. As the search has stretched over six weeks, many residents hope a capture will bring life back to normal.
“I hope that they capture him soon, and I hope that us as community members and around the area keep our eyes open and report anything suspicious,” said Clark.
