The federal government owns and administers certain lands within the State of Utah under the auspices of the Bureau of Land Management (BLM), the US Forest Service (USFS), the National Parks Service (NPS), U. S. Bureau of Reclamation (BOR), and the U.S. Fish and Wildlife Service (FWS). These“public lands” are held by the federal government in a proprietorial interest only. Accordingly, federal law enforcement authority on these public lands is limited to that authority delegated to it by the U. S. Constitution, and specifically by Article IV, Section 3, Clause 2 (the Property Clause). Federal law enforcement is, therefore, limited to the enforcement of rules and regulations which are “needful” for the protection of the public lands. The State of Utah, as sovereign within its borders, retains full police powers on the public lands to enforce its civil and criminal laws and ordinances in the protection of the public’s health, safety, and welfare.
