Gray wolves (Canis lupus) are present in Colorado today. Their presence is a conservation story unfolding in two parts: the slow, natural return of individual animals and a recent, state-mandated effort to restore the species. This complex re-establishment marks a significant shift in Colorado’s wildlife landscape, driven by conservation goals and a historic vote. Understanding the current situation requires looking back at how the species was lost and detailing the distinct processes that have brought it back to the Rocky Mountain state.
Historical Presence and Extirpation
Gray wolves were once widespread across Colorado, inhabiting most of the state’s diverse landscapes before European settlement. These apex predators played a natural role in regulating populations of large prey animals, such as elk and bison, across their native range. The arrival of settlers and the subsequent development of the livestock industry led to an intense and systematic campaign to eradicate the species.
Government-sponsored predator control programs, which utilized trapping, poisoning, and shooting, were highly effective in removing wolves across the American West. By the 1940s, the gray wolf was considered extirpated from Colorado, meaning the species no longer existed in the wild within its historical state habitat. This removal fundamentally altered the natural ecological balance of the region for nearly a century.
Natural Recolonization and Current Status
While the species was officially gone for decades, the successful reintroduction of wolves to the Northern Rocky Mountains in the 1990s set the stage for a natural return to Colorado. As wolf populations in states like Wyoming and Idaho grew and dispersed, individual animals began to venture southward along the mountain corridors. Confirmed sightings of dispersing wolves in Colorado began sporadically in the early 2000s, suggesting the state still offered suitable habitat and prey.
The first confirmed pack to establish itself in the state arrived around 2019-2020, migrating from Wyoming into the northwestern corner of Colorado. This group, known as the North Park Pack, was significant because it produced the first wolf pups born in the state in approximately 80 years. This baseline population exists separately from the later, more structured releases.
The Colorado Reintroduction Program
The most significant step toward restoring the wolf population was taken by Colorado voters, who narrowly approved Proposition 114 in November 2020. This initiative was historic, as it marked the first time citizens of a U.S. state mandated the reintroduction of a species via a ballot measure. The proposition required the Colorado Parks and Wildlife (CPW) Commission to develop and implement a plan to reintroduce gray wolves to designated lands west of the Continental Divide by December 31, 2023.
The CPW developed the Colorado Gray Wolf Restoration and Management Plan, which established a goal of releasing 30 to 50 wolves over a three-to-five-year period to create a self-sustaining population. The initial release events occurred in late December 2023, when CPW successfully translocated ten wolves sourced from Oregon onto public lands in Grand and Summit counties. These wolves were selected to maximize genetic diversity and minimize the risk of returning to their capture locations.
The reintroduction effort continued with a second phase, including the release of fifteen wolves translocated from the central interior of British Columbia in January 2025. A core component of the voter mandate was the requirement for CPW to establish a program to pay fair compensation to livestock owners for any confirmed losses caused by the reintroduced wolves. Furthermore, the plan explicitly prohibits the commission from imposing any land or resource use restrictions on private landowners.
Geographic Distribution and Management
The current wolf population in Colorado is primarily distributed across the Western Slope, west of the Continental Divide, as mandated by Proposition 114. The naturally occurring North Park Pack established itself in Jackson County, while the mandated releases have focused on remote public lands within Grand and Summit counties. These areas provide the necessary vast, high-quality habitat and abundant prey, such as elk and deer.
Management of the wolves is overseen by CPW under the Restoration and Management Plan. CPW utilizes monitoring techniques like GPS collars on released animals to track their movements and distribution. The wolves are currently classified and protected under state law, with CPW managing the population to balance conservation goals with human-wildlife conflict mitigation. The compensation fund for livestock losses is a central feature of the management strategy, designed to foster coexistence with agricultural communities.
