Yellowstone National Park has released its annual report for 2018 detailing the status of wolves in and around the national park. Officials called the population “stable,” despite a decrease in numbers of pups.

“In 2018 we noted a drop in pup numbers,” said Doug Smith, Yellowstone Wolf Project leader. “However there were no intra-species wolf killings, which is usually the reason for the most wolf mortality. This year marks a 10-year period of relatively stable wolf numbers. While the reasons for this are unknown, a relatively stable elk population is likely a large factor.”
