This bill originally focused narrowly on requiring the Public Lands Policy Coordinating Office to map large tracts of public land and identify forest health problems. A substitute version significantly broadened the bill to add sweeping new legal assertions about state authority over federal land in Utah. The revised bill declares that Utah has never ceded legal control over roughly 35 million acres — about 96% of federally controlled land in the state — where the federal government holds what the bill calls a "proprietary interest" (meaning it owns the land like an ordinary landowner but lacks specific constitutional authority to govern it), and it directs state agencies to presume that all federal land in Utah falls into this category unless the federal government proves otherwise, extending state claims of authority over matters like zoning, land use, health and safety, and enforcement of state law on that land. Separately, the bill still requires the office, by 2028, to digitally map contiguous "landscape-scale lands" of 250,000 acres or more, marking public access points, high-value mineral areas, and forested "landscape public nuisance areas" — locations the Division of Forestry, Fire, and State Lands may flag based on factors such as tree density, disease, and fire risk — with annual updates and mineral-development recommendations reported to the Legislature's Federalism Commission and its Natural Resources, Agriculture, and Environment Interim Committee.
