A rally to protest sport hunting and trapping of wolves in the United States drew about 150 participants on Saturday outside the gates of Yellowstone National Park, an organizer said.

Demonstrators at the event in Gardiner, Montana, at the northwest entrance to the park called for an overhaul of government wildlife management policies for the animals.

Thousands of wolves have been legally hunted, trapped or snared in the three years since the predators were removed from the federal endangered and threatened species list in the Northern Rockies and western Great Lakes.
