Colorado's majestic bison are getting a new lease on life, thanks to legislative developments that will impact how these animals are managed in the state. Colorado Parks and Wildlife (CPW) has embarked on creating a comprehensive management plan for the Book Cliffs bison herd, which will now be recognized both as wildlife and domestic animals in Colorado, following Governor Jared Polis' signing of Senate Bill 25-053 into law. CPW's move paves the way for preservation efforts and addresses concerns related to the bison's habitat and potential interactions with other species, including human activities in the region.

Before this legislative change, a bison crossing from Utah into Colorado could find itself without legal protection, but the new classification aims to fix that. The heart of the management plan revolves around a habitat assessment, where CPW will be looking at food and water availability and considering the dynamics of coexistence with other wildlife and domesticated creatures such as livestock and free-roaming horses. However, this isn't just about counting grass blades or mapping out water sources; it's about preserving a legacy and ensuring that these colossal creatures continue to grace Colorado's landscape, in balance with the ecosystem and local interests, according to the Colorado Parks and Wildlife.

With a keen eye on sustainability and ecological balance, the forthcoming management plan will establish objectives for a wild bison population within a designated zone and create strategies to prevent damage associated with the herd. CPW also plans to delineate how to manage bison that meander beyond their allocated space. This initiative will involve collaborative conversations with various stakeholders, seeking input from Tribal and Indigenous groups, local producers, private landowners, and the public at large.

As the plan takes shape, CPW encourages those interested to have their voices heard by signing up for CPW's E-Newsletter or by visiting Engage CPW. Set to come into effect on Jan. 1, 2026, the Book Cliffs bison will benefit from protections afforded by Senate Bill 25-053, but there's work to do before then. At the November Parks and Wildlife Commission Meeting, commissioners will vote upon proposed regulation changes that include defining the parameters between wild and domestic bison, informed by public feedback and discussions that have been on the table since at least the October 9 commission meeting.

Colorado Parks and Wildlife, which operates primarily on revenues from license sales and state park fees, is responsible for the stewardship of 43 state parks and more than 350 wildlife areas spanning about 900,000 acres. The agency's work in managing and facilitating outdoor activities, including hunting, fishing, and wildlife watching, is not just a testament to its commitment to conservation but also a significant economic driver for Colorado, with an annual impact estimated at around $6 billion.
