The main purpose of this legislation, known as the "Snowmobiles Aren't Weapons Act" or the "SAW Act," is to protect mammalian predator species on federal land by prohibiting the use of motor vehicles for hunting or harming these animals. The goal is to ensure the conservation of wildlife and to prevent unethical hunting practices that could threaten these predator populations. The key provisions of the act include a strict prohibition against using motor vehicles to intentionally harass, pursue, hunt, shoot, wound, kill, trap, capture, or collect mammalian predators on federal land.
