A Special Virtual Presentation of the Institute for Science & Policy and Colorado State University’s Warner College of Natural Resources, in partnership with the Center for Collaborative Conservation, the Center for Human-Carnivore Coexistence, CSU Extension, and the Denver Museum of Nature & Science
After a nearly 80-year absence, gray wolves appear to be on the verge of returning to Colorado. In July 2019, a lone radio-collared wolf became the state’s first confirmed Canis lupus sighting in the wild in years. Then, in January, a separate pack appeared in Moffat County in northwest Colorado. This November, voters will go to the polls to determine the fate of Ballot Proposition 114 which, if passed, would charge the Colorado Parks and Wildlife Commission with formally reintroducing wolves no later than 2023.
The potential return of this charismatic and controversial species has sparked a wide range of passionate reactions. Some Coloradans praise the restoration of an endangered apex predator to its ancestral range while pointing to the associated ecosystem benefits. Others are wary of the economic impact on agriculture and the challenges of adding wolves to the increasingly populated Western Slope. For generations, wolves and humans have navigated a fraught dynamic of coexistence. So what does the science tell us about the pros and cons of wolves returning to our backyard? And, if wolves are in Colorado’s future, how can society have an effective dialogue that uses science to inform policy and management?
In this special five-part webinar series, we explored wolf reintroduction through the lens of science, policy, and lived experiences. Our diverse group of panelists discussed the current state of wolf populations, dove into the data about the species’ role in the ecosystem, talked trade-offs, and heard firsthand stories from those who’ve already been living amongst wolves in other parts of the U.S.
Episode 1: The Science of Restoring Wolves to Colorado
We discussed wolf-related policy and the latest ecological and social science research pertaining to wolf ecology, interactions with big game and livestock, and public perceptions of wolves.
Panelists: Stewart Breck, Research Wildlife Biologist, USDA Wildlife Services, and Kevin Crooks, Director, Center for Human-Carnivore Coexistence, and Professor, Department of Fish, Wildlife, and Conservation Biology, CSU
The conversation was moderated by John Sanderson, Director, Center for Collaborative Conservation, and Kristan Uhlenbrock, Director, The Institute for Science & Policy.

You introduce the wolves then expect Ranchers to compromise how does that work...I don't get it

Lived for 45 years where they released ten wolves in radium. Hardly a wilderness area, 5000 people a day in the summer rafting there, wolves should have a lot to eat. Who resurched this hair brain idea! The people who want wolves live in boulder and denver, release them there.

Be careful. Idaho was told the goal of reintroduction was a population of 100 wolves that would live in the remote wilderness. Now we are up to 1500+. They are very difficult to manage and keep under control.

That sounds like a stable, natural population to me. In Colorado the estimated *minimum* population size for sweeping environmental benefits is 750. Idaho is mostly empty anyway so I'm not sure what you're on about.

@@Reed411 The original goal in Idaho was 150. Their population has exploded disrupting elk populations in certain areas. We are aggressively managing them through hunting and trapping with year round seasons. Left on their own, they will expand until we run out of elk, then wolf populations will crash again.

@@elkhuntr2816 I’m sorry, but 150 wolves for the entire state of Idaho is laughable. In any other instance, that kind of population size over that large of a land mass would be cause for serious concern. Hunting communities in CO are also concerned about the effect on elk populations. And although it is true that elk populations drop in a very meaningful way with the presence of apex predators, that does not mean they will disappear entirely. They merely will go back to their pre-colonial population sizes. Elk in particular are huge mammals and their population sizes especially in the West have exploded over the past 100 years taking huge tolls on native ecosystems and carrying a huge risk of disease. CWD is perfect example of what can happen when predators are not there to mediate the weak and sick. I understand the concerns of hunters who enjoy their elk tags, but establishing healthy trophic ecosystems for our future generations and curbing the effects of human impact and climate change (that includes biodiversity) far outweigh the hobbies we enjoy doing. And if you hunt for food, no worries, the elk will still be there.

@@Reed411 "’m sorry, but 150 wolves for the entire state of Idaho is laughable." Biologists would disagree as they set that number back in 96. Now I think the realistic target is around 750. Each wolf kills an average of 20 elk per year. At 1500 wolves, that's 30,000 elk killed by wolves alone every year. That's more than the 20,000 or so killed by hunters. Our current elk population is around 120,000 so that is a big number. Combine just those 2 numbers and that is a reduction of the elk poplation almost in half just to sustain the wolves. Just look at the history of conservation, it works. Wolf populations today are the result of conservation.

@@elkhuntr2816 Then it looks like the wolves are doing a great job at managing elk populations. Remind me now why we need hunters doing 20,000+ elk a year in harvest. I'd also remind you that the final benchmark for the state's reintroduction plan was hit in 2011 when they were taken off the endangered species list. Since then their numbers have been on the rise AND YET the largest elk harvest in the state's history was in 2015 followed by big years in 2016, 2017 and then again in 2020. Elk harvests year over year in the state of Idaho have only ever increased. Let's face it, now that wolves are back, the real existential crisis to the elk population is man. Own up. Idaho doesn't want to lose its big prize winning elk populations, and they don't want to share the game with wolves. That's what this is all about.

Other than a surviving population, what is the intended outcome of a thriving wolf population? Its amazing how all the advocacy never talks about what the goal to the world will be. Its all "wait and see" while we seek out positives.

@@Redstoneprime316 so why not more tags the way we've always done it? How do you deal with wolf overpopulation? People hungry for dog meat? Because every year they hand out tags and they're all snatched up. Utah does an over the counter walk in and buy tag if there are unclaimed extras. Why manage population with a non-native species of wolf?

Wolves are amazing incredibly efficient and intelligent killing machines may Colorado's Deer and Elk population rest in peace they don't just prey on the weak and old they lay waist to every thing...just visit Yellowstone and try to find an Elk....I hope these irresponsible introductions don't migrate to Utah

I was at Yellowstone last year and saw a herd of elk. A simple google search states Yellowstone's elk population is being managed and will be fine. In fact, the wolves are helping refine the elk into more resilient and hardier herds that don't overgraze and damage the park. What logic are you using to come to the conclusion that wolves are bad for the environment that they evolved in for thousands of years? Wolves are a driving force in the circle of life and the balance of the ecosystem. Removing them will unravel that chain, as we've seen in Yellowstone and lead to environmental collapse in the long run. Humans are fooling themselves in believing they can manage the complexities of nature.

Deer and elk spread CWD on the ground, and in the winter hay they hang around. That can spread to livestock.
