The Real Significance of Colorado's First Wolf Pups

You may have heard the great news: Colorado has its first officially documented wild wolf pups in more than eight decades. Six pups have been spotted by Colorado Parks and Wildlife (CPW) agents. This is wonderful. And those pups now entering the wild world are clearly significant. But as I researched the birth, I realized that the pups are only one of several significant aspects of this event. Let’s look at some others. 

The wolves that produced the premier pups are collared and designated as F1084 and M2101. The female, F1084 (pictured at top of post), has been living in northern Colorado near the Wyoming line since July of 2019. She dispersed from Wyoming’s Snake River pack near Yellowstone in search of a mate. Sometime last year, she somehow connected with a four-year old, 110-pound male in good health. In February of this year, CPW collared that male and gave him the number M2101. He was the first wolf ever collared by CPW, another significant detail of this birth.


An interesting side note to this historic event is that F1084 when she entered Colorado was known as M1084—“she” was considered a “he.” This was due to a clerical error when she was collared in 2017. So when CPW found another male accompanying M1084, officials considered the two males to be hunting partners. 


But when data from M1084’s collar revealed what could be denning behavior—staying in one place for long periods of time—CPW agents figured there might be more than hunting going on. They contacted Wyoming Game & Fish Department and asked them to double check their records. Sure enough, a blood sample revealed M1084 was F1084. 


The starting of a family by F1084 and M2101 was so significant it was covered by media across the US and even internationally. Kris Middledorf, area wildlife manager for CPW, said in a press release, “It’s incredible that these two adult animals have traveled the distance and overcome the challenges they have to get here, and to now have pups in Colorado,”


Distance and challenges indeed. Colorado has not been a safe destination for wolves. A handful of dispersers have reached the state but most have ended up dead: poisoned, hit by a car, shot illegally, or killed by a hunter who claimed he thought he shot a coyote. For F1084 to have survived in Colorado for two years is very significant.


That she actually reached Colorado from Wyoming is also significant. As I have written before, Wyoming’s wolf management plan amounts to creating a wolf prison in the northwest corner of the state on the public lands that surround Yellowstone and Grand Teton National Parks. Wyoming calls this prison its Wolf Trophy Game Management Area. Data from Wyoming Game & Fish Department (WGFD) reveals that almost every one of the state’s wolf packs roam within the trophy zone most or all of the time. 



Trophy hunters need a license to kill in the zone and there are limits to how many wolves can be taken in the three-to-six-month long hunting season. If a wolf evades trophy hunters and disperses from the trophy zone, it then enters the 85% of the state where it can be shot on sight, anytime, anywhere, by anyone. No license needed. Wyoming calls this area surrounding the trophy zone its Predator Zone. In a recent year 24 wolves were reported killed in the Predator Zone. That’s just the number reported. I wouldn’t be surprised if others were shot and not reported. They are, after all, considered vermin in the Predator Zone.

Of course, F1084 couldn’t see prison walls designated by lines on a map when she felt compelled to disperse. She didn’t know she might go from being sought as a trophy to being slaughtered as vermin. She just knew that she had to go find a mate. And for reasons known only to her, she chose to head south toward Colorado. 


As the map above shows, it’s only about 250 miles (not a long wolf journey) from the wolf prison to elk-filled northwestern Colorado where all of Colorado’s few confirmed wolf sightings have occurred. There are ample elk and deer to take along the way. 


Somehow F1084 escaped the prison, survived the Predator Zone, and reached Colorado. Her journey and survival may be even more miraculous than that of Oregon’s famous wolf OR-7. He dispersed from northeastern Oregon to northern California. While on his longer journey, OR-7 was almost always protected by the Endangered Species Act. But F1084 had not a shred of protection in Wyoming’s Predator Zone.


Yet another significance of this first Colorado breeding pair is the home territory—Jackson County—the wolves chose. Most of Jackson County sits in a high basin surrounded by mountain ranges. The area has been known for wildlife. At one time many bison lived in the area and the basin was hunting ground for the Ute and Arapaho tribes. While the bison are now gone, elk and deer remain and will provide sustenance for a growing wolf family. 



Jackson County is the fourth least populated county in Colorado. The county’s population has fallen since 1980 and as of the 2010 census, only 1,394 people lived there. That head count is significant.
 

A while back, three scientists wrote a journal paper, “A Framework for Envisioning Gray Wolf Recovery.” The scientists, John Vucetich, Jeremy Bruskotter, and Michael Nelson, believe wolf recovery is feasible in the Lower 48. They calculate that wolves will recover best where fewer than 142 of us humans crowd each square kilometer. With only 1,394 people in 4,177 square kilometers, Jackson County has less than one person per square kilometer. That’s clearly good news. The potentially bad news is that a number of Jackson County residents are cattle ranchers, a group that typically does not like coexisting with wolves.


But like it or not, more wolves are coming to Colorado. Last year Colorado voters narrowly approved Proposition 114, which directs CPW to reintroduce wolves to the state by the end of 2023. The people who voted for wolf reintroduction mainly lived in the urban areas of the state. But people in the rural areas—areas like Jackson County—overwhelmingly voted against reintroduction. 


Some of those voters against reintroduction are now claiming that these first pups are significant because their birth shows that Colorado does not need to reintroduce wolves; the animals will naturally repopulate the state. History proves them wrong.


When 66 wolves were reintroduced into the Rocky Mountains in Yellowstone and central Idaho in 1995, conservationists hoped that those wolves and their descendants would create a healthy population that would in turn produce dispersers that repopulated the Rocky Mountains and the West. 

That hope became reality—with the help of federal protection under the Endangered Species Act. Dispersers increased Montana’s wolf population. By 2008 dispersers of reintroduced wolves had created the first confirmed packs in Oregon and Washington. By 2020 dispersers had even made the long trek to California and created at least one pup-producing pack. Yet by 2020 dispersers had not formed a single breeding pair in Colorado, the only Rocky Mountain state still without a permanent wolf population. 

If wolves can’t survive a natural journey to Colorado, they can be reintroduced. And protected. Wolves are an endangered species under Colorado law. Killing one can result in a $100,000 fine and up to a year in prison.

Proposition 114 will bring more wolves to Colorado just about the time that Colorado’s premier pups are ready to breed, start their own packs, and help create a genetically healthy, self-sustaining wolf population. And that accomplishment will be incredibly significant.

One State's Wolf Prison Reveals Need for Federal Wolf Protection

When wolves were reintroduced into the Rocky Mountains in Yellowstone and central Idaho in 1995, conservationists hoped that these wolves and their descendants would create a healthy population that would in turn produce dispersers. Dispersal is a fact of wolf life; wolves regularly leave their birth packs in search of food, open territory, or a mate to start a pack with. 

By 2008--with the help of federal protection under the Endangered Species Act-- that hope became reality: dispersers of reintroduced wolves had created the first confirmed packs in Oregon and Washington. By 2020 dispersers that had made the long trek to California had established the state’s only pack, one with a breeding pair and 13 other members. 

Yet by 2020 dispersers had not established a single breeding pair in Colorado, the only Rocky Mountain state still without a permanent wolf population. This shortage of successful dispersers speaks to the necessity of ESA protection for wolves.


A handful of dispersers did reach Colorado but most ended up dead: poisoned, hit by a car, and killed by a hunter who claimed he thought he shot a coyote. In July of 2019 a collared male disperser from Wyoming’s Snake River pack arrived in northwest Colorado and is still in the state according to the Colorado Parks and Wildlife website. 


In January of 2020, Colorado Parks and Wildlife confirmed that a pack of six wolves, mostly brothers and sisters, was living in northwestern Colorado. Since most of those wolves are related, reproduction is unlikely without unrelated dispersers reaching the state and finding the pack.  


But they better hurry. In September of 2020, the Center for Biological Diversity reported that at least three of the six wolves in that pack had been illegally shot and killed.


So that’s it: After a quarter-century of wolves successfully dispersing elsewhere across the West, Colorado has a confirmed lone wolf and three survivors of poaching. 


Why Don't Dispersers Reach Colorado? 


Wyoming, right on Colorado’s northern border, has a well established wolf population that generates dispersers. So I looked at Wyoming’s wolf management plan, and the more I dug into that plan, the more I saw how Wyoming has created what I call a wolf prison that keeps dispersers from reaching Colorado.



As the map above shows, Wyoming’s prison sits in the northwest corner of the state on the public lands that surround Yellowstone and Grand Teton National Parks. Wyoming calls this prison its Wolf Trophy Game Management Area (WTGMA). Recent data from Wyoming Game & Fish Department reveals that almost every one of the state’s 50 or so wolf packs roam within the trophy zone most or all of the time. 


Trophy hunters need a license to kill in the zone and there are limits to how many wolves can be taken. In 2020, 31 wolves were killed in the trophy zone.


If a wolf isn’t killed in the trophy zone, it can still be killed trying to escape, to follow that natural urge to disperse. When a wolf disperses from the trophy zone where it can be hunted three to six months of the year, it enters the 85% of the state where it can be shot on sight, anytime, anywhere, by anyone. No license needed. Wyoming calls this area surrounding the trophy zone its Predator Zone.


Of course, a wolf can’t see prison walls designated by lines on a map when it is compelled to disperse. Consider a wolf who busts out and heads south in search of elk, a favorite meal. Plenty of elk can be found between the Wind River Reservation that sits at the southeastern corner of the prison and the Colorado border, according to three web sites oriented to elk hunters. So the escaped wolf may take an elk right away or continue south. 


As the map below shows, in about 250 miles (not a long wolf journey), the escapee—if not shot on sight anytime, anywhere, by anyone—could reach elk-filled northwestern Colorado, where all of Colorado’s few confirmed wolf sightings have occurred.



But with the way Wyoming has set up the prison, an escapee’s chances of reaching Colorado are deathly slim. Last year 24 wolves were reported killed in the Predator Zone, according to Wyoming Game & Fish. That’s just the number reported. I wouldn’t be surprised if others were shot and not reported. They are, after all, considered vermin in the Predator Zone. 


Yet that collared male from Wyoming’s Snake River pack escaped the prison, survived the Predator Zone, and reached northwestern Colorado. His escape and survival may be even more miraculous than that of Oregon’s famous OR-7 that dispersed from northeastern Oregon to northern California. While on his longer journey, OR-7 was almost always protected by the Endangered Species Act. But the Snake River escapee from wolf prison had no protection in the Predator Zone.


Wyoming’s Management Necessitates Reintroducing Wolves to Colorado 


Clearly, the prison system Wyoming uses to manage wolves keep dispersers from reaching Colorado—a state with plenty of elk and suitable wolf habitat. Surely some of those 24 wolves killed in the Predator Zone—probably many of them—were heading towards Colorado when they were senselessly killed. If they had reached Colorado, those dispersers could have found one another, bred, and created a permanent wolf population. 


If wolves can’t walk to Colorado, they can still be trucked in. Proposition 114, which Colorado voters approved in November 2020, instructs their Parks and Wildlife Department to develop and implement a science-based plan for reintroducing gray wolves to the state. 


The impact of Wyoming’s wolf management plan on Colorado’s wolf population reveals why dispersing wolves need federal protection under the Endangered Species Act. When federal protection is stopped and management is handed over to individual states, one state’s approach can stop dispersing wolves from reclaiming territory in a neighboring state. Just as Wyoming’s Predator Zone has stopped wolves from reclaiming habitat in Colorado.
