Noted conservationist Jane Goodall says state and federal government actions are threatening wolf packs in Denali, Yellowstone and elsewhere. Photographs by Thomas D. Mangelsen
I went to Denali in August in search of wild wolves.
It was my first trip to the national park, and I was especially looking
forward to seeing the descendants of the pack that biologist Adolph
Murie had come to know so well. Murie’s study, begun in 1939 and
continuing today, is the source of much of what we know about wolves in
their natural habitat. (Pictured here: A gray wolf from the Grant Creek
pack in Denali National Park, Alaska, in 2012.) Thomas D. Mangelsen

Wolves are highly intelligent, have a rich emotional
life and are an intensely social species. They remain with their
parents for at least three years, learning how to be good pack members,
and they are likely to grieve over the death or disappearance of a
companion. (Here, Grant Creek pack wolves stretch before patrolling in
2006.) Thomas D. Mangelsen

Wildlife photographer Tom Mangelsen (whose images
you see here) had told me countless stories about the Denali wolves, and
during our four days in the Alaska park he drove me to all the places
he has watched and photographed them. (In this image from 2006, a young
Grant Creek pack wolf plays catch-up.) Thomas D. Mangelsen

It was a marvelous experience: Grizzly bears, moose,
caribou, Dall sheep, a red fox and other wildlife provided a great
show. But we did not see or hear a single wolf. The removal just four
years ago of a buffer zone prohibiting the hunting of wolves outside the
park is having a devastating impact. (Here, Jane Goodall and Tom
Mangelsen on the porch of Murie Cabin, used by Adolph Murie during his
landmark studies.)

Wolves travel long distances in search of prey, and
they do not understand that they may be killed if they stray over
invisible boundaries. (Here, a wolf feeds on a Dall sheep in Denali’s
Taklat River in 1990.)

Those responsible for managing wolf populations
typically think in terms of the species as a whole; they calculate the
number of wolves that an environment can support or lose. But it is
important to remember that each pack is composed of bonded individuals.
When leaders are killed, the pack and its traditions may disintegrate.
When breeders are killed, the pack’s survival is threatened even more
directly. (Here, a Grant Creek pack wolf photographed in 2009.)

That’s what happened to Denali’s Grant Creek pack. A
pregnant female and another wolf from the pack were ensnared in 2012 by
trappers who had set out a horse carcass as bait. The only other
breeding female of the pack was found dead a short time later. There
have been no pups since. Tom showed me the Murie den site that the pack
had occupied since the 1940s — and abandoned after the deaths. It is
believed that there are only a few scattered members left from what was
once the most famous wolf pack on Earth. (Here, a pup howls to its Grant
Creek pack mates in 2008.)

Overall in Denali, only 59 wolves were seen in the
last count. The National Park Service boasts that Denali is one of the
best places in the world for people to see wolves in the wild. Just a
few years ago, a visitor’s chance of seeing a wolf there was nearly 45
percent; today it is less than 12 percent. (Here, tourists watch a Grant
Creek pack wolf lazing in the road in 2006.) Thomas D. Mangelsen

Yellowstone National Park may be headed toward a similar future. (Here, a wolf in Yellowstone’s Lamar Valley in 2009.) Thomas D. Mangelsen

It was during a 2001 trip to Yellowstone that Tom
showed me my first wild wolves, in the distance, through a spotting
scope. (Here, the Druid Peak pack on patrol in 2008.) Thomas D. Mangelsen

It was a very cold day, but numerous people were
there, dressed in warm clothes, eager to identify individual wolves by
their markings, colors and behavior. (Here, a similar group of
wolf-watchers gathers near Yellowstone’s Slough Creek in 2008.) Thomas D. Mangelsen

In October 2012, however, Wyoming’s gray wolves were
removed from the endangered species list. So now, if a wolf roams
outside Yellowstone, it can be killed legally. A limited trophy-hunting
season is in effect immediately outside the park from October through
February. Beyond that perimeter, wolves are considered “predatory
animals” and can be killed year-round — trapped, poisoned or even shot
from the air. A competition last weekend across state lines in Idaho
offered $1,000 to the person who killed the biggest wolf. (Here, the
Druid Peak pack howls on a ridge in 2008.)

Already, at least 119 gray wolves have been killed
since the delisting in Wyoming. Eight of these were Yellowstone wolves
that biologists had fitted with radio collars to study their behavior.
And among those was a wolf known to visitors as 06, for the year she was
born. Her death shocked and saddened the scientists and tourists who
had come to respect this wise breeding female. (Here, the Druid Peak
pack tests a bull bison in 2008.) Thomas D. Mangelsen

Hunting eradicated wolves from the Yellowstone area
once before — back in 1926. Reintroduction involved a huge effort, but
it was beneficial to the ecosystem, research and the tourism industry.
Now, unless the federal government reconsiders the delisting of
Wyoming’s gray wolves, or the state changes its management policies, all
of that stands to be lost. (Here, two Druid Peak wolves cross the snowy
landscape of Yellowstone’s Lamar Valley in 2008.) Thomas D. Mangelsen
