 The National Park Service said on Friday it intends to ban hunters from baiting bears in national preserves in Alaska. The new rule, set to take effect later this summer, would bar sport hunters from using baits such as bacon grease, pastries, syrup, or dog food to attract bears, the agency said in a statement. Baiting encourages bears to become conditioned to human-provided food, increasing the likelihood of negative human-bear interactions, they said.
