Canyon’s Law

Standard Summary
Comprehensive overview in 1-2 paragraphs
Canyon’s Law would ban the use and placement of M-44 devices (sodium cyanide-based “cyanide bombs”) on public land and require the removal of any such devices already present. The bill defines M-44 devices and public land, and requires that within 30 days after enactment, federal, state, or county agencies that have deployed an M-44 on public land remove them. The accompanying findings document the high toxicity of sodium cyanide, potential harm to people and non-target wildlife, and documented incidents involving humans and animals, including endangered species. The overall aim is to eliminate the use of these devices on public lands to protect public safety and wildlife.
Key Points
- 1Prohibition on use and deployment: Preparing, placing, installing, setting, deploying, or otherwise using an M-44 device on public land is prohibited.
- 2Removal deadline: Within 30 days after enactment, any Federal, State, or county agency that has placed an M-44 on public land must remove it.
- 3Definitions and scope: An M-44 device is any device designed to propel sodium cyanide when triggered by an animal; “public land” means land under the jurisdiction of a public land management agency; includes common names like M-44 ejector device or M-44 predator control device.
- 4Public land management agencies: The bill explicitly references the National Park Service, U.S. Fish and Wildlife Service, Bureau of Land Management, Bureau of Reclamation, and the Forest Service as public land management agencies affected.
- 5Findings and rationale: The bill’s findings describe sodium cyanide’s toxicity, past incidents involving people and animals, widespread non-target harm, and ongoing risks to endangered species, framing the prohibition as a protective measure for people, wildlife, and ecosystems on public lands.
Impact Areas
Primary group/area affected- Public land management agencies (federal, state, and county) and their wildlife or predator-control programs; public land users (recreational visitors, hikers, campers) who could be affected by changes in land management practices.Secondary group/area affected- Livestock producers and ranching operations that previously relied on M-44 devices for predator control; non-target wildlife and domestic animals (dogs, pets) that could be impacted by exposure on public lands.Additional impacts- Potential changes in wildlife management policy and pesticide regulation on public lands; administrative and removal costs for agencies; possible legal and enforcement considerations given the removal requirement; no explicit penalties are described in the provided text, and private land uses are not addressed by the bill.
