From The High Country News (Ethan Linck) [March 1, 2020]:
The last wolf resident in Colorado in the 20th century died in 1945 at the edge of the San Juan Mountains, where a high green country falls into dark timber near the headwaters of the Rio Grande. It was caught by its leg in the ragged jaws of a steel trap, set by federal authorities following reports that it had killed 10 sheep.
If the wolf was mourned, it wasn’t mourned by many. Contemporary newspaper articles reflected widespread support for ridding the West of wolves. “Wolves are like people in that they must have their choice morsel of meat,” wrote Colorado’s The Steamboat Pilot in an April 1935 story on the retirement of William Caywood, a government contract hunter with over 2,000 wolf skulls to his credit. “(Some would eat) nothing but the choice parts of an animal unless they were very hungry. Wolves are killers from the time they are a year old.”
Seventy-five years later, public perception has changed, and otherwise clear-eyed Westerners regularly wax poetic over Canis lupus. “Colorado will not truly be wild until we can hear the call of the wolf,” opined one writer in a recent editorial for Colorado Politics. “That mournful sound rekindles primordial memories of our ancestors, and to most of us, brings a state of calmness that nothing else can approach.”
Wolves, it turns out, may be a part of the world we want to live in after all.
This about-face is more than conjecture. According to a recent poll of 900 demographically representative likely voters, two-thirds supported “restoring wolves in Colorado,” echoing similar polls over the past 25 years. Yet state wildlife officials have been reluctant to comply, wary of the toxic politics surrounding reintroduction in the Northern Rockies.
In response, activists seized an unprecedented strategy. A coalition of nonprofit groups in Colorado, led by the recently formed Rocky Mountain Wolf Project, spent 2019 tirelessly gathering support to pose the question to voters directly through a 2020 ballot initiative. They succeeded, delivering more than 200,000 signatures to the Colorado secretary of State. Initiative 107 was officially ratified in January and will be voted on this November. (Meanwhile, neither politicians nor wolves have stayed still. In January, a state senator introduced a controversial bill to regain legislative control of the issue; in the same week, Colorado Parks and Wildlife confirmed that a pack of at least six wolves was now resident in northwest Colorado, though it’s far from clear they represent the start of a comeback. For the moment, the future of wolves here still likely rests on the initiative.)
A new transplant to Colorado from the Pacific Northwest, I learned about the campaign from a canvasser outside Whole Foods in north Boulder on a sunny June day last year. In a parking lot filled with Teslas and Subarus, the tattooed volunteer stood opposite a wall-sized advertisement for the store, featuring the smiling faces of ranchers and farmers on the Western Slope.
It was a scene that would have done little to assuage fears that urban liberal voters were forcing reintroduction on rural residents. The canvasser caught my eye as I left the store. “Can I talk to you about reintroducing wolves to Colorado?” he asked, waving a pamphlet. I demurred and walked back to my bike. But the initiative and its backers — happy to use scientific justifications for their cause, paired curiously with populist rhetoric about its overwhelming public support — lingered in my head.
The initiative fascinated me, beyond its potential to transform the landscape of my adopted home. As an academic biologist, I tended to think science should be both privileged in debate and somehow above the fray. But my own environmental ethic operated on an independent track — drawing on the scientific literature when it supported my opinions, and claiming it was beside the point when it didn’t. The Rocky Mountain Wolf Project reminded me uncomfortably of this contradiction.
If voters decide to reintroduce wolves to an increasingly crowded state from which they were effectively absent for over 70 years, Colorado’s ecosystems and rural communities may change rapidly, in unexpected ways. Yet unlike nearly all other major wildlife management decisions, the choice would rest not with a handful of experts, but with the public.
The case poses a thorny set of questions. What will happen if wolves return to Colorado? When, if ever, can science tell us what to do? And, in the face of empirical uncertainty, could direct democracy be the best solution?
I wondered: If I knew my own research could dramatically affect ecosystems and livelihoods, would I want it to play more of a role in public life — or less?
CONSERVATIONISTS OFTEN HESITATE to frame arguments in moral terms, leaning on the perceived authority of empiricism to buttress their positions. At the same time, many conservation debates are complicated by the collision of disparate worldviews, where evidence is almost beside the point. Large carnivores — intensively studied and politically controversial — fall squarely in the center of this push-and-pull between data and belief.
In 1995, federal biologists released eight gray wolves from Alberta, Canada, in Yellowstone National Park, seeding a population that eventually grew to as many 109 wolves in 11 packs. With the wolves came the unique opportunity to test the theory that their influence on elk numbers and behavior reduced grazing pressure on riparian vegetation, with consequences for the very structure of rivers themselves.
Preliminary data suggested that this process — known as a trophic cascade — was indeed in effect. Elk numbers were down, grazing patterns were different, tree growth was up, and at least some river channels appeared to recover. A tidy encapsulation of the idea that nature had balance, it had broad appeal: In a viral YouTube video from 2014, British environmentalist George Monbiot breathlessly described these changes over soaring New Age synthesizers and stock footage of an elysian-seeming Yellowstone, calling it “one of the most exciting scientific findings of the past half century.”
Yet ecology is rarely simple, and as the mythology surrounding the return of wolves grew, so, too, did skepticism in the literature. Over the past 15 years, a cascade of papers has called into question most of the findings taken for granted in the popular account of Yellowstone’s transformation. Elk browsing might not be reduced in areas with wolves; streams and riparian communities had not returned to their original state; maybe beavers were more fundamentally important to these processes than wolves were. In sum, a 2014 review paper suggested that there are no “simple, precise, or definitive answers” to the question of whether wolves caused a trophic cascade in the park; another evocatively concluded that “(the wolf) is neither saint nor sinner except to those who want to make it so.”
Yellowstone represented a single experiment — one possible outcome among many. In a different corner of the West with more people, or different habitats, or more or fewer elk — in Colorado, for example — would wolves have had the same effect? Last June, a paper in the journal Biological Conservation attempted to answer this question indirectly by aggregating data on species reintroductions and introductions around the world and asking whether their removal or addition caused a reversion to historic conditions. Unsurprisingly, the answer was “it depends”: Restoring predators has unpredictable, complex consequences.
That paper’s lead author, Jesse Alston, was a graduate student in the Department of Zoology at the University of Wyoming. I met him on a bright fall day in Laramie, at a coffee shop in a strip mall on the east side of town. Driving up from Boulder the same morning, I marveled at the abrupt transition in landscape at the border between Colorado and Wyoming: In the span of only a few miles north of Fort Collins, the sprawl of the Front Range fades away, and the High Plains begin rolling up into a sepia-colored saucer from the flatter, hotter agricultural land of eastern Larimer County.
Alston spoke quietly and slowly, in the cautious manner of someone who anticipated a long future working with wildlife and wildlife-related controversies. Though he thought the evidence favored trophic cascades in Yellowstone, he was circumspect about predicting whether wolf reintroduction in Colorado would have the same effect. “(It) really hinges on the idea of there not being adequate predation currently. And there are a lot of hunters in Colorado.” But hunters are a minority of trail users, he added, and recreation of all kinds can influence elk behavior much the way fear of wolves does.
I asked him to elaborate on the role of science in justifying carnivore restoration and whether he thought it might backfire. He paused, thinking, then said: “I think the people who would be most turned off if you don’t see large-scale ecosystem effects are the people who are least inclined to listen to science anyway, so I don’t see that being that big of a deal. But I do think that — as scientists, particularly as good scientists — that we should be sure that our ideas are buttressed by empirical findings.”
Of course, there are empirical findings, and then there are the caveats that always accompany them — the reasons we can’t say for sure what will happen when wolves return. “I think really where the science-policy nexus is most problematic has been when there’s misunderstanding of uncertainty,” Alston continued. “I think it’s good to advocate for causes that we believe in, but we should be pretty straightforward about discussing the uncertainty that comes along with that.”
IF WOLVES ARE NOT an ecological magic bullet, it is not readily apparent in the literature of the Rocky Mountain Wolf Project, which nonetheless aims to “disseminate science-based information” as part of its mission. On its website, a blog post suggests that since wolf reintroduction to Yellowstone, “the ecosystem has balanced.” This isn’t wrong, necessarily. But it isn’t correct, either, and the simplification belied a willingness to use science as a political battering ram. I was on board with the group’s mission as a voter, a Coloradan. As a scientist, though, it made me uneasy.
Though the Rocky Mountain Wolf Action Fund is itself young — founded at the end of 2018 — its roots go back nearly to the release of wolves in Yellowstone, through its Boulder-based predecessor, Sinapu. In 2008, Sinapu — whose name was taken from the Ute word for wolves — was folded into Santa Fe-based WildEarth Guardians, which also sought to restore large carnivore populations to the Southern Rockies. On an October evening at a brewery in South Boulder, I asked Rob Edward — founder and president of the board of the wolf fund, longtime Sinapu employee and the public face of wolf reintroduction in Colorado for decades — why the group had chosen to emphasize what might be described as the spiritual resonance of the effects of carnivore reintroduction on ecosystems and landscapes.
Edward was eloquent but blunt, a middle-aged man who dressed in a way that suggested he was as comfortable in the rural parts of the state as in Boulder. His wife, Anne Edward, also a longtime wolf advocate, joined us; she was quieter, with gray hair and eyes that lit up whenever wolves were mentioned. They had chosen their language based on polling data, Rob Edward said. “They use that term — ‘restoring the balance of nature.’ Now, is it an oversimplification of a tremendously complicated system? Absolutely. Do I care? Not really.” At the same time, he said, the connection to research and its perceived authority was important. “The public as a whole places a tremendous amount of stock in scientists.”
While it was clear the couple would support reintroduction even if they were the only two people on earth in favor of it, they nonetheless viewed public opinion as validating. A ballot initiative was a necessary last resort, a way to force the state and its slow-moving wildlife officials to comply with the will of the people of Colorado. “We’re not excluding experts, we’re simply telling them, get it done!” Rob Edward said, pounding the table in a gesture that passed unnoticed against the backdrop of his general animation. “Figure it out! Don’t keep machinating about it for another five decades. Get it done!”
As I listened to him, I again found myself deeply conflicted at the prospect of the ballot initiative, and at putting major wildlife management decisions up to a simple vote. On the one hand, I appreciated that it was a creative solution to an intractable political problem, on behalf of a natural system divorced from the political ebb and flow of Denver. On the other, it seemed to set a dangerous precedent. As the history of our complicated relationship with wolves shows, popular opinion can be capricious. Was it really right to pose complex questions — questions at the limit of expert understanding — to a largely naive public?
Laws that translate science to policy can give a voice to a nonhuman world that cannot advocate for itself. Yet in our society, democracy is haunted by the question of whose voices matter. Edward was clear that polling showed clear majorities of Coloradans support wolf reintroduction across the state, including groups that you might expect to oppose it: Rural residents on the Western Slope, hunters and Republicans all support it by a substantial majority. But Colorado is changing, becoming less white, and he was unable to refer me to data broken down along racial and ethnic lines — particularly among historically disadvantaged groups that remain underrepresented at the ballot box.
Nor have the views of Indigenous people — who have the longest history of cultural connection to wolves, and whose lands in Colorado will likely be among the first impacted by a rebounding wolf population — been highlighted in the debate. I was unable to reach wildlife officials with the Southern Ute Tribe by press time, but they are clearly watching the issue closely. In a statement on the initiative, the tribe clarified that it does not have an official position on wolf reintroduction and is “simply evaluating whether (to) support, oppose, or remain neutral on the subject.”
SCIENCE IS VERY GOOD at addressing the how, but often fails when confronted with the should — the biggest questions, which veer into the realm of values. There is no experiment we can conduct to say whether we should proceed with wolf introduction, no data that can tell us if it is the right thing to do. It comes down to how evidence is filtered through our worldview: whether we think of humans as a part of nature or separate from it, and whether we think changes in grazing habits and water channels — and the presence of wolves themselves — add up to a fundamental good worth fighting for.
But, like conservationists, scientists often shy away from such moral judgments, and for valid reasons: the fear of being perceived as not impartial, thereby undercutting the authority of their research; a sense of obligation to the politically diverse taxpayers who fund their work; an acute awareness of the limitations of their data, statistics and the scientific method itself. In the public sphere, however, this feigned objectivity can have the negative consequence of suggesting there are scientific solutions to philosophical questions.
That wolf reintroduction advocates lean on science rather than those weightier themes is understandable. Yet arguing that having wolves in Colorado is an intrinsic good — because they represent what we want Colorado to become, not because they will have a net benefit on aspen growth or stream hydrology — would be more honest, and might win people over in unexpected ways.
Back at the brewery in suburban Boulder, Rob Edward vacillated between polished language justifying reintroduction in scientific terms and moments of raw emotion: “They have wolves on the Gaza Strip. They have wolves in Italy. They have wolves in Northern-freaking-California. Why can’t we have wolves here?”
IF THE BALLOT INITIATIVE passes this November, a three-year planning process begins, followed by what Anne Edward described as “paws on the ground” — the release of the first few wolves — in 2023, almost certainly in the San Juan Mountains. Advocates anticipate that this process will be difficult, and they are prepared for a fight.
A successful reintroduction would be a remarkable accomplishment, given the fraught history of wolves in Colorado, as well as a landmark event in the gradual return of large carnivores to the 21st century West. It would also be a remarkable reflection of the blurring lines between science, belief and politics in the 21st century. As political gridlock becomes a feature of daily life, and environmental degradation — the cancerous rot of the Anthropocene — metastasizes, the impulse to circumvent collapsing institutions in response to crises is likely to become more common. In these circumstances, what role should scientists and science play? How much should uncertainty prevent action, and how much should empiricism determine our value system?
There are no easy answers here. If the basic question of whether or not to reintroduce wolves to Colorado is largely beyond the purview of science, then perhaps putting it to a vote is the most responsible option. The messiness of democracy can be terrifying. Still, there may not be a better way. After all, the language of values has been a part of the modern conservation movement since its birth — the Endangered Species Act of 1973, for example, states that endangered species provide “esthetic, ecological, educational, historical, recreational, and scientific value to the Nation.”
Toward the end of my conversation with the Edwards, thinking of their many years of advocacy and of the curious arc of history, I asked them what it was like to see an end in sight. “Do you allow yourselves to get a little carried with the fantasy of it?” I asked. “Things are in your favor — have you started imagining ‘paws on the ground’?”
Both were quiet for a moment, and the noise of the bar washed over us. “I’ve been working on this for 25 years,” Rob said, his voice breaking into a sob as Anne reached out and gripped his arm. “I certainly do.”
