Federal Public Lands Crimes — Timber Theft, Arson, Trespass, and Resource Crimes on Federal Land

The United States government owns hundreds of millions of acres managed by the Forest Service, Bureau of Land Management, National Park Service, Fish and Wildlife Service, and other agencies. Protecting that land and the resources on it from theft, destruction, fire, and unauthorized use is partly a matter of federal criminal law. Title 18 U.S.C. Chapter 91 (§§ 1851-1866) covers a range of public-lands offenses: stealing coal and timber from federal land, setting or negligently leaving fires in forest areas, damaging survey markers, placing hazardous devices on federal land, and violating certain National Park Service regulations. These statutes work alongside civil trespass remedies, permit sanctions, archaeological-resource laws, and general federal crimes such as arson, conspiracy, or theft.

Current Law (2026)

Legal Authority

• 18 U.S.C. § 1851 — Coal depredations: wrongfully taking, selling, or disposing of coal from any land owned or reserved by the United States is a misdemeanor punishable by fine and up to 1 year imprisonment; this includes unauthorized coal mining operations on BLM-managed land
• 18 U.S.C. § 1852 — Timber theft: cutting, destroying, or removing timber from U.S. public land with the purpose of exporting or disposing of it commercially is a federal crime; the statute has been a key tool against commercial timber theft from national forests
• 18 U.S.C. § 1853 — Tree damage: cutting, chipping, girdling, or otherwise injuring or destroying standing trees on federal public lands, Indian reservations, or tribal lands is a separate criminal provision from timber theft; covers vandalism and damage even without the commercial conversion element. For crimes committed specifically in Indian country, see Federal Criminal Jurisdiction in Indian Country
• 18 U.S.C. § 1855 — Forest arson (see also Federal Arson and Explosives Law): willfully setting fire to timber, underbrush, grass, or other combustibles within the limits of any national forest, on any lands reserved or purchased for timber, or within the water-source protection areas of national forests, or near such areas so as to endanger them, is a felony carrying up to 5 years; wildfire arson on federal lands generates substantial prosecution interest given the public safety and resource destruction involved
• 18 U.S.C. § 1856 — Unextinguished fires: starting any fire on or near national forests or protected lands and leaving it unattended without fully extinguishing it is a federal crime; this provision addresses negligent fire starts as well as intentional arson; "Smokey Bear" fire prevention messaging is legally backed by this statute
• 18 U.S.C. § 1857 — Fences and livestock trespass: destroying, breaking, or opening fences, hedges, or gates enclosing public lands held for public use, or driving, allowing, or inducing livestock to enter such lands in violation of law, is a misdemeanor; this provision protects managed grazing programs and wildlife habitat on federal lands
• 18 U.S.C. § 1858 — Survey marker destruction: intentionally destroying, damaging, moving, or removing any corner post, survey marker, or other official government survey monument — such as section corners, quarter-section corners, or bench marks — on public, private, or tribal land is a felony; survey markers are fundamental to property descriptions across the American West
• 18 U.S.C. § 1864 — Hazardous devices on federal lands: setting, placing, or erecting any device (trap, wire, hook, spike, or similar) on federal land with intent to harm or kill any person or animal, or setting such devices to prevent or obstruct law enforcement or resource management, is a serious felony; the statute was enacted partly in response to "eco-terrorism" tree spiking, where metal spikes driven into trees destroy chainsaw blades and injure loggers
• 18 U.S.C. § 1865 — NPS violations: violating rules and regulations promulgated by the National Park Service under its general authority (54 U.S.C. § 100751(a)) is a federal misdemeanor carrying up to 6 months imprisonment; this provision gives criminal enforcement authority to the entire NPS Code of Federal Regulations (36 C.F.R. Parts 1–199)
• 18 U.S.C. § 1866 — Archaeological and historic resources: violating federal laws governing archaeological resources, historic preservation, and antiquities is a crime punishable by fine and mandatory restitution; defendants must pay the full cost of restoration and repair of damaged historic or archaeological resources

How It Works

Chapter 91 is a collection of specialized land-management crimes, not a general prohibition on misconduct on federal land — each offense targets a specific resource harm with a federal-land nexus. Fire offenses split by intent: 18 U.S.C. § 1855 addresses willful fire-setting on or near National Forest land, while § 1856 covers negligent failures — leaving a fire unattended or unextinguished — without requiring intent to cause harm. Resource-theft offenses frequently travel with charges from other statutes: timber theft, equipment theft, and downstream sale of unlawfully taken resources can simultaneously implicate the Lacey Act, general federal theft provisions, fraud counts, and conspiracy charges. § 1865 functions differently from the others — it operates by criminally enforcing valid NPS regulations, so the operative conduct is defined in the applicable Title 36 park regulation rather than in the criminal statute itself. Archaeological and cultural-resource prosecutions under § 1866 are typically paired with ARPA charges, theft counts, and restitution demands covering restoration, repair, and archaeological appraisal value. The specific offense structures for each resource category are detailed in the sections below.

Timber Theft: An Ongoing Problem

Commercial timber theft from national forests and BLM lands is a significant and chronic problem, particularly on the Pacific Coast where high-value timber species grow. Poachers cut old-growth trees — including famous "ghost trees" (bleached deadwood), rare burls used for decorative furniture, and high-value cedars — from national forests and sell them to lumber yards and wood product manufacturers. The federal timber theft statutes (§§ 1852–1853) work alongside the Lacey Act's prohibition on buying and selling illegally taken timber to create a framework for prosecuting both the theft and the downstream sale of stolen wood.

Timber theft operations can involve small-scale opportunistic cutting or large organized operations that steal millions of dollars of timber. Federal enforcement relies on Forest Service officers, BLM rangers, and cooperation with state law enforcement.

Wildfire Arson and the Fire Criminal Provisions

The federal fire crimes (§§ 1855–1856) are particularly significant given the scale of wildfire damage in the American West. A single arson fire can destroy hundreds of thousands of acres, kill firefighters, and cost hundreds of millions of dollars to suppress. Federal prosecution of wildfire arson has traditionally been difficult because of the challenges of proving intentional causation in large fires. The § 1856 provision on unextinguished fires addresses the more common scenario of negligent fire starts — campers who leave a fire, off-road vehicle riders who start fires with exhaust sparks, or railroad operations where sparks from trains ignite trackside vegetation.

The § 1864 Hazardous Device Statute

Section 1864 was enacted in 1988 largely in response to "tree spiking" — a tactic used by some forest activists who drove metal spikes into trees to prevent logging. When a chainsaw hits a metal spike, the chain can break violently, injuring or killing the sawyer. The statute's broader reach covers all kinds of booby traps set on federal lands, including anti-law enforcement devices and hunting-related traps that endanger hikers and rangers. The penalty escalates dramatically if the device causes serious injury or death.

National Park Service Regulations

Section 1865 gives criminal enforcement teeth to valid NPS regulations issued under the Park Service's statutory authority. In practice, many common federal citations in parks come through specific Title 36 rules on matters like wildlife disturbance, closures, vehicles, camping, fires, weapons, boating, or resource protection. That means the operative conduct is often defined by the regulation first and the misdemeanor penalty second. Park rangers have authority to enforce these provisions.

How It Affects You

If you recreate on federal public lands: The fire provisions (§§ 1855–1856) apply to everyone — campers, hunters, hikers, and off-road riders — who starts a fire on or near federal lands. Leaving a campfire unextinguished on federal land is not just bad practice; it is a federal crime. The NPS violations provision (§ 1865) means that entering closed areas, disturbing wildlife, or ignoring posted regulations in national parks can result in a federal criminal citation.

If you work in the timber, mining, or extraction industries: Federal timber and coal theft statutes (§§ 1851–1852) apply not just to the person who cuts the tree but to anyone who buys, transports, or processes stolen federal resources. The Lacey Act's civil and criminal penalties for trafficking in illegally taken timber apply at the end of the supply chain as well as the beginning.

If you own or operate land adjacent to federal public lands: Survey marker destruction (§ 1858) is a serious federal crime that occasionally arises in boundary disputes between private landowners and federal agencies. Destroying or moving a survey marker — even on what you believe to be your own land — can constitute a federal offense if the marker defines the boundary of federal land.

If you work for BLM, Forest Service, or NPS: The public lands criminal statutes are tools in your enforcement toolkit alongside civil trespass authorities and administrative permit revocations. Assaults on rangers and federal land-management officers are separately prosecuted under Assault on Federal Officers. Understanding which offenses require federal criminal prosecution versus administrative action is important for enforcement planning.

State Variations

Federal public-lands crimes do not categorically displace state criminal law. Jurisdiction depends on the type of federal land and the jurisdictional arrangement for the site. In many parks, forests, and BLM areas, states can still prosecute overlapping crimes under state law, while federal officers and prosecutors pursue federal counts where the land or resource statute applies. Coordination is common in major fire, timber-theft, archaeological, trespass, and resource-damage cases.

Implementing Regulations

• These crimes are mostly statute-driven: Chapter 91 itself contains the criminal prohibitions, while land-management agencies use separate regulations and permit systems that can trigger or complement enforcement.
• 36 CFR 1.3 — General penalties for violating National Park Service regulations, the main regulatory penalty provision linked to many § 1865 prosecutions
• 36 CFR Chapter I — National Park Service regulations governing closures, resource protection, vehicles, camping, wildlife, and other conduct that can lead to misdemeanor enforcement in park units
• 43 CFR Subchapter B and related bureau rules — BLM land-use, trespass, and resource-protection regulations that more often support civil or administrative enforcement but can overlap factually with Chapter 91 crimes

Pending Legislation (119th Congress)

As of April 8, 2026, no enacted federal law has materially rewritten the core Chapter 91 public-lands criminal provisions summarized here. Congress continues to legislate around wildfire, public-lands management, cultural-resource protection, and recreation enforcement more broadly, but this page should be read based on the current 18 U.S.C. §§ 1851-1866 structure unless Congress enacts a change.

Recent Developments

• Wildfire-related enforcement remains a major practical driver: Fire-setting and negligent-fire cases keep §§ 1855-1856 relevant, especially in western states where federal lands and wildfire risk overlap heavily.
• Timber and specialty-wood theft still matter operationally: Federal and state officers continue to use timber-theft and trafficking laws against unlawful cutting, burl poaching, and related downstream sales.
• Cultural-resource and device cases remain highly fact-specific: §§ 1864-1866 are comparatively niche statutes, but they still matter in serious cases involving hazardous traps, archaeological damage, or deliberate destruction of protected resources.
• As of April 8, 2026: The main changes in this area are enforcement-priority and land-management driven rather than statutory; the underlying criminal provisions themselves are relatively stable.
