Wolves move to YNP headquarters, den near Mammoth
By BRETT FRENCH - Billings Gazette - 05/02/09
BILLINGS — The sound of howling wolves and wolf sightings are becoming regular occurrences at Yellowstone National Park’s headquarters in Mammoth, Wyo. The wolves have even made nighttime elk kills in the backyards of park employee housing.
This spring, a pack of wolves already conditioned to humans has moved from the park’s interior to near its Northeast Entrance, just south of Gardiner.
“It’s an intensive management situation,” said Doug Smith, the park’s lead wolf biologist. “They’re a habituated pack. Photographers love them. But we’re seeking out opportunities to teach them a lesson — that walking through a developed area or near people is not a good idea.”
The pack of four wolves — three black males and one gray female — have denned just a quarter-mile east of Mammoth. As a result, wolves have been spotted around the small community — the same place the U.S. Army set up shop in 1891 to protect the park. The town includes the historic Mammoth Hot Springs Hotel, a visitor center, shops, government offices and employee housing.
The pack migrated from Canyon off and on throughout the winter, Smith said, referring to the area around the Grand Canyon of the Yellowstone. The small pack is likely the remnants of the nearby Hayden pack, which was a favorite with tourists in Hayden Valley because they were so visible.
But the Hayden pack’s alpha male and female were killed by the nearby Mollie’s pack from Pelican Valley. Confined to the east by the bison-killing wolves of Mollie’s — some of the biggest wolves in the park — and the Gibbon Meadows pack to the west, the Hayden pack was under constant threat. Living close to humans, where the other wolves didn’t venture, helped them to survive.......
