This bill, titled the "Gunnison Outdoor Resources Protection Act of 2025," establishes a comprehensive framework for land management and conservation in Colorado, primarily within Gunnison County. Its overarching goal is to conserve, protect, and enhance the natural, scenic, scientific, cultural, watershed, recreation, and wildlife resources for present and future generations. The legislation achieves this by designating several new categories of protected areas and expanding existing wilderness. The bill designates nine Special Management Areas (SMAs), eight Wildlife Conservation Areas (WCAs), four Protection Areas , and two Recreation Management Areas (RMAs). It also establishes the Rocky Mountain Scientific Research and Education Area . These designations cover significant acreage and aim to balance conservation with specific management objectives tailored to each area's unique characteristics. A significant provision involves expanding the wilderness system in Colorado by amending the Colorado Wilderness Act of 1993. This includes designating new wilderness areas like Matchless, East Cement, and Star Peak Wildernesses, and adding substantial acreage to existing ones such as Maroon Bells-Snowmass, West Elk, Uncompahgre, and Powderhorn Wildernesses. These areas will be managed under the strict protections of the Wilderness Act. Across all designated areas, management prioritizes resource conservation and enhancement. The use of off-highway vehicles and bicycles is generally restricted to existing designated roads and trails, with provisions for winter travel management plans and potential new trail development. Exceptions are made for administrative purposes and emergencies. Key protective measures include the withdrawal of all designated covered areas and wilderness areas from public land laws, mining laws, and mineral and geothermal leasing. The bill prohibits commercial timber harvesting and mandates that ecological restoration projects be collaboratively developed, focusing on small diameter materials and prescribed fire. It also includes provisions for seasonal closures to protect wildlife and mandates wet meadow and riparian restoration projects. Beyond land designations, the bill addresses other critical aspects, such as withdrawing certain federal land in Delta County from oil and gas leasing and imposing "no surface occupancy" restrictions elsewhere. Importantly, it directs the Secretary of the Interior to take approximately 19,080 acres of tribally-owned land into trust for the Ute Mountain Ute Tribe , explicitly prohibiting gaming activities on this land while affirming existing water rights and tribal treaty rights.
