S 2179 United States Senate · 119th Congress

Canyon’s Law

S 2179, "Canyon’s Law," bans the use of M-44 devices (sodium cyanide-based poisoners) on public lands managed by federal agencies like the National Park Service, U.S. Fish and Wildlife Service, and Bureau of Land Management. The bill prohibits placing, deploying, or using these devices on public land and requires all existing devices to be removed within 30 days of enactment. It directly affects federal land management agencies and any entity currently authorized to use M-44s, such as state wildlife or livestock control programs. The law aims to prevent further harm to people, non-target wildlife (including endangered species like eagles and bears), and pets, following documented incidents of poisoning and animal deaths.
