Wolf population reaches new high at Yellowstone park

Figures show the number of wolves has continued to grow despite efforts to remove the gray wolf from federal protection under Endangered Species Act

The number of wolves in Yellowstone National Park has continued to grow amid a push to remove the gray wolves from federal protection.

New figures from the park show that there were at least 104 wolves in 11 packs in Yellowstone in December last year, including nine breeding pairs, with 40 pups surviving until the end of the year.
