The main purpose of this legislation, known as "Canyon's Law," is to ban the use of M-44 devices, commonly referred to as "cyanide bombs," on public land. These devices are designed to kill certain animals, such as coyotes and wild dogs, that are suspected of threatening livestock. The law aims to protect both people and wildlife from the dangers posed by these toxic devices. Key provisions of the law include a complete prohibition on the preparation, placement, or use of M-44 devices on public land.
