The livestock industry has been running a smear campaign against wolves for years.
It intensified when the Colorado Cattlemen’s Association joined forces with the Rocky Mountain Elk Foundation, the Colorado Farm Bureau, the National Rifle Association’s electioneering arm, and the Colorado Woolgrowers’ Association to oppose Proposition 114 — a 2020 citizens’ ballot initiative requiring Colorado to reintroduce wolves to the western part of the state.
Fearmongering was a big part of the campaign to prevent the restoration of wolves to their native Colorado habitats: The hunting groups peddled the narrative that wolves would kill all the elk. The ranching interests claimed that wolves would drive cattle and sheep operations out of business.
Notably, neither outcome has materialized since the 1995 wolf reintroductions in Yellowstone and Idaho, and indeed elk populations and cattle and sheep ranches there remain abundant three decades after wolves returned. In 2020, the Stop the Wolf Coalition lost the election, 51% to 49%. But the hysteria over livestock losses from wolves was only beginning.
So it makes sense to put these fears, and the livestock industry messaging that amplifies them, into perspective.
Weather events can kill a lot of cattle. In 2007, a single blizzard caused an estimated 15,000 cattle deaths in Colorado, according to the Colorado Cattlemen’s Association. In 2024, a single lightning strike knocked 100 cattle off their feet, killing 32 of them as well as a rancher, who was engaged in branding the calves. That’s more than Colorado wolves have killed in an entire year. The weather slaughters far more livestock than predators in the state.
Then there is cattle rustling. In late 2025, 23 cattle disappeared in a single incident on the High Plains of northeastern Colorado, and law enforcement characterized the incident as unlikely to be random chance and likely meant they had been stolen. In 2024, 187 cattle went missing on the Uncompahgre Plateau in Western Colorado. Fifteen of them eventually turned up, demonstrating that missing cattle are sometimes simply lost by inattentive ranchers. The Colorado brand inspector estimated in mid-December of that year that about 500 cattle were expected to be reported missing for the year in the state.
Mystery deaths and sickness also plague Colorado’s cattle herd. In May of 2025, 15 cattle in south-central Colorado in a single day. Was it eating poisonous plants? An abandoned oil well on the property? Water contamination? While some sort of toxin was suspected, there have been no definitive answers. A 2010 USDA report calculated that 38.9% of all cattle lost in 2007 died from sickness, injury, or poisoning. Only 0.1% of the losses were attributable to predators of any kind.
In Colorado, the number of cattle killed in slaughterhouses in 2025 was 2,269,600, according to the USDA’s Livestock Slaughter Report. The number of calves slaughtered in the state was “[w]ithheld to avoid disclosing data for individual operations,” but would presumably add to that total.
The most important predator of cattle in Colorado, by a vast margin, was humans. Specifically, the livestock industry has raised such a hue and cry over a comparatively tiny number of wolf-caused mortalities. We have met the enemy (of cattle, at least), and he is us.
It’s hard to tell how many cattle and sheep have been killed by wolves, because 聽lump together livestock that are killed with livestock that are injured, but recover.
There were 13 cattle killed or injured by wolves in the two years prior to the wolf reintroduction, or an average of 6.5 cattle per year. In the slightly more than three years since reintroduction, there have been 44 cattle killed or injured by wolves, 37 sheep and one llama. That’s an average of 15 cattle and 12 sheep confirmed killed or injured per year.
The fraction of Colorado’s livestock losses attributable to wolves is minuscule, and some of the state’s news outlets are starting to get it. The general public, and lawmakers in particular, need to be aware of the tiny proportion of Colorado’s 2.6 million cattle that are falling prey to wolves, and we can all rest easy in the knowledge that when a livestock loss is reported, and wolves are suspected, there is a full investigation.
And when a wolf kill is confirmed, the rancher in question gets a payment from the state that not only covers his losses, but might also cover up to seven times the value of the animal(s). That’s an excessive level of generosity, which creates a perverse incentive to blame wolves.
But when ranchers are getting paid 鈥� in fact, paid far more than the fair-market value they deserve 鈥� when beef is what’s for dinner for one of Colorado’s new population of wolves, who really cares whether the diner is wildlife or human?
