A
Disturbance in the Valley: Wolves in the Northern Rockies
By Martin Rowe

It is dawn in early June in the Lamar Valley in
the northeastern corner of Yellowstone National Park, Wyoming. The bison,
elk, deer, and moose have come down to the valley to eat the succulent
grass before the heat of the day and the summer months force them to move
up the mountains where it is cooler. The expected rains have already begun,
joining the snowmelt that has swollen the rivers in this lush watershed.
The newly born young of the bison, elk, and deer are taking their first
tentative steps, accompanied by their mothers and the watchful males of
the tightly knit herds. Bald eagles perch on the numerous lodgepole pines
that are the dominant arboreal species in this dry climate, 7,500 feet
above sea level. Along the roadside stand wildlife watchers and their
telescopes, scanning the peaceful scene before them and waiting.
Theyre looking for a mild disturbancea slight shifting of
the herds, the raising of heads staring intently in one direction, perhaps
a fluttering of ravens. This is the most vulnerable time for the herbivores,
as their young cannot yet outrun the predators who know that this is one
of the best places to catch the vulnerable. Soon enough, there is a disturbance.
Although the bison and elk herds seem to tolerate the presence of predators,
they make sure the latter do not get too close, nonchalantly watching
them as they move on the periphery of the herd. There is also a disturbance
in the wildlife watchers. Could it be him? They hadnt seen him
for a year. He had disappeared from the Lamar Valley; perhaps, they had
wondered,
he had joined another group or been killed. But the dark-hued markings
confirmed other recent sightings: the gray wolf known as 104 was definitely
back.
Four Years of Wolves
People have been able to see wolves such as 104 in Yellowstone
since January 12, 1995 when 15 wolves were reintroduced into the Park
after, it is believed, an absence of almost 70 years Once spread across
the entire North American continent, canis lupus (the gray or Timber
wolf) was virtually extinct in the lower 48 states by the 1930s. In spite
of this, pockets of these tenacious survivalists remain in the northern
Rockies, northern Minnesota, Wisconsin and Michigan and in the southwest.
A related species, the red wolf or canis rufus, is being reintroduced
to the southeast, while there are plans to reintroduce the gray into northern
Maine [see sidebar] and the Adirondacks.
Since 1995, the number of wolves in Yellowstone has grown to over one
hundred individuals, aided by further reintroduction of wolves and the
fact that the females often produce four to eight cubs in each litter.
Nevertheless, the reintroduction of wolves continues to be a controversial
issueand not just to those who didnt believe that wolves should
ever have come back from the brink of extinction. After the reintroduction
began, the American Farm Bureau Federation brought a suit against Secretary
of the Interior Bruce Babbitt and the reintroduction program, stating
that the program endangered the livestock of its members and that wolves
had never been eradicated from the Yellowstone area and thus shouldnt
have been reintroduced. In late 1997, U.S. District Court Judge William
Downes declared the reintroduction program illegal, a decision that was
then immediately appealed by Predator Project, Defenders of Wildlife and
the National Wildlife Federation. The hearing of this appeal took place
at the end of last month.
For Tom Skeele, Executive Director of Predator Projectan environmental
group that works to conserve predators and their habitats, which was initially
opposed to the wolf reintroductionthe issue was not that wolves
should not be in Yellowstone, but whether they would be protected once
they were reintroduced. The wolves were reintroduced under the special
designation nonessential experimental of the Endangered Species
Act (ESA). This means that animals, generally considered endangered or
threatened under the Act, are reintroduced into areas with fewer restrictions
than populations listed as endangered. For organizations such as Defenders
of Wildlife or National Wildlife Federation (NWF) the designation was
necessary. According to NWF: The experimental designation
for wolves in Yellowstone and central Idaho [where wolves were also reintroduced]
played a critical role in reassuring ranchers and resource industries
that wolves would not unduly affect their livelihoods.... Wolf reintroduction
would not happen without the public support made possible by the experimental
designation.
One of the problems, however, said Skeele in an interview with Satya,
is that once the wolves leave the Park they can be killedthey get
caught in traps set for coyotes, they are shot and trapped legally after
conflicts with livestock, or shot illegally. All of the wolves [around
25 to 30] that have been killed in the last three years in these ways
were killed outside the Park, he commented. Skeele also wondered
whether the fact that wolf numbers may be starting to plateau in Yellowstone
signaled that the available habitat within the Park boundaries may already
have been saturated and that this was why wolves were leaving the Park.
According to a recent report by Predator Project: Protection of
wolves and their habitat quickly declines outside of our national parks
and wilderness areas, which in turn limits wolf numbers and distribution.
This is because wolf numbers are self-regulating within a given area,
so the core recovery areas are limited in the numbers of wolves they can
support. Just four years after the reintroduction, Yellowstone Park may
be already at capacity for wolves. (Billings Gazette, 3/1/99).
Skeele is concerned that because of this habitat disruption, there will
be an island population of wolves in Yellowstone, unable to join with
wolves in central Idaho and/or northwest Montana (including Glacier National
Park), and create a contiguous, breeding population. For Skeele, the issue
also extends beyond wolves. He agrees that the wolf reintroduction program
has been successful [see sidebar], and admits that wolves under the nonessential
experimental status in Yellowstone and central Idaho are doing better
than fully protected wolves in northern Montana. Yet, recent attempts
to reintroduce the Mexican gray wolf into New Mexico and Arizona have
met with mixed results. According to the World Society for the Protection
of Animals, five of the 15 wolves released into the Apache National Forest
have been illegally shot to death, two are missing and presumed
dead, and another has died of unknown causes. Furthermore, what
works for wolves does not work for other threatened or endangered animalssuch
as bear and lynxwho emphatically do need Federal protection, since
they are not as hardy, do not breed as fast, and require a more intact
ecosystem to survive. There are also plans to reintroduce the grizzly
bear into central Idaho under the nonessential experimental
status.
As might be expected, the exaggerated fears of cattle ranchers that wolves
would prey on their livestock rather than on the populations of elk, deer,
bison, or moose have not been realized. By the end of 1997, wolves had
killed only 50 cattle and about 200 sheep, while a year later the total
loss of money to livestock owners was less than $70,000. Not only was
this loss less than one-third of expected losses (and only two percent
of all reported livestock losses due to predators), but it was less than
half a percent of all livestock loss due to starvation, cold winters,
or disease in the region. Furthermore, Defenders of Wildlife compensated
ranchers for all losses due to wolf predation.
From Least to Most Popular
The wolves tenacity and capacity to travel has in
fact created one of the controversies. Not only did wolves migrate south
by themselves from Canada into Glacier National Park in northern Montana,
but by the end of 1998 they were in the Grand Tetons in Wyoming, and were
expanding from central Idaho to Oregon, the Bitterroot Valley in western
Montana, and elsewhere. Currently, there are 100 or so wolves in the Yellowstone
area, 100 in central Idaho, and 80 or so in northern Montana. Questions
remain, however, including two fundamental ones: How many breeding femalesthe
fundamental criterion for a sustainable populationare within those
groups, and how many functioning packs are there? Moreover, the wolves
are still surrounded by enemies. The states of Idaho, Wyoming and Montana
remain hostile either to the reintroduction, state protection, or habitat
protection of and for the wolves. Wolves who return to Alberta can be
legally killed nine months of the year on public lands and can be widely
hunted throughout British Columbia. According to Fish and Wildlife Service,
only when the wolves reach a critical level of 10 breeding pairs for three
years can wolves be downlisted (meaning that they would be
removed from the status of endangered and classified as threatened
thus subject to fewer Federal protections).
Since reintroduction, wolves have become the focal point for the three
million tourists who visit Yellowstone every year. The wolf adorns the
front cover of the Wildlife Watchers Guide and shares pride of place
with the grizzly bear in the numerous pamphlets in the Park. The reintroduction
of the wolf to the larger Yellowstone ecosystem (an area encompassing
11 million acres) has also meant that this corner of the U.S. is now the
only intact ecosystem in the lower 48 states, meaning that all the species
indigenous to the ecosystem remain within the system. Even those who protested
wolf reintroduction because it would mean the death of more elk and bison
have to acknowledge that while wolves kill an estimated 700 elk each year
(mainly very young calves and old females), human predators kill many
more, about 1,000 to 1,400 of the 20,000-strong herd each year. The predated
species are in turn showing greater awareness and alertness as their old
enemies move among them.
The wolf named 104 wasnt the only wolf in the Lamar Valley that
day in June. A lighter-colored gray wolf also entered the Valley, both
in search of the 800-pound elk carcass that had been the food source for
bears, ravens, eagles and a coyote for a few days. The watchers wondered
what would happen when the two met. They circled one another briefly,
and then the lighter-colored wolf adopted a submissive posture and they
began to play. It turned out that the wolves once belonged to the same
pack, and that more than likely the older dark-hued wolf had helped the
lighter-colored wolf when the latter was a cub. They stayed with each
other for a few momentsrenewing their connection after a yearbefore
they separated again, running off in different directions and into a still
uncertain future.

Wolves in Northern New England
A recent study sponsored by New Yorks Wildlife Conservation
Society indicates that wolves are not likely to return to the northeast
from Canada by themselves, reports the New York Times (June 1,
1999). There are only two natural corridors between Quebec and Maine;
otherwise the wolves would have to run across highways, railroads and
swim the St. Lawrence River. Moreover, once in Maine, the wolves may mate
with the abundant coyote population and create an impure gene pool. A
report by Canadian scientists has found that the eastern Canadian and
American wolf is a different species from the northern gray or Timber
wolf. If the wolf, therefore, is to be reintroduced to northern New England,
it will have to be from the population in Quebec.
The battlelines are similar to those in the West. Wolf reintroduction
advocates argue that wolves will return the ecosystem to its previous
equilibrium; the ranchers say the wolves arent welcome. There are
abundant moose, deer, and beaver populations for the wolves to feed on;
the ranchers say they will eat the cattle and sheep. However, wildlife
biologists argue that wolves would have more a chance in northern New
England, where there is more core habitat for wolves than in the Adirondacks,
where there are also plans for reintroduction.M.R.
Among the Survivalists
Tom Skeele, Executive Director of Predator
Project, explains why the Bozeman-based environmental group is opposed
to the current wolf reintroduction program.
There is an attitude in the northern Rockies that is called Shoot, Shovel
and Shut Up. And if we dont have any kind of legal ability to go
back and say to people, No you cant do that, and not
have any kind of enforcement follow-up to that, then Shoot, Shovel and
Shut Up is basically sanctioned. What were [Predator Project] saying
is, Lets let [the wolves] come back home alone. Lets
be patient.
There [are] three reasons why it would be a good thing to let them come
back alone. One is that theyd come back with full protections [under
the Endangered Species Act], which would be good for them. Secondly, is
that they would come back, having come from Canada and Glacier [National
Park], down through Montana and into Yellowstone. They would have learned
how to stay out of trouble because they cross lots of roads. They would
have crossed types of ranchlands. And the ones that would have got here
would have learned how to stay out of trouble. Its not a genetic
knowledge but a learned behavior that would be very valuable over time.
The third reason, which I learned from a wolf biologist who is a state
senator in the Glacier area, [goes like this]: Think about this
attitude that Montanans and the people in the northern Rockies have: tenacious
individuals, self-reliant. So if a wolf is going to make it back on its
own, run the gauntlet, and get here on its own, as opposed to being picked
up by a helicopter and dragged here by the Federal government, then I
think the locals are going to have more respect. I think thats
true. You hear more screaming about the wolves in Yellowstone from the
ranching community and the locals than you ever do in northwestern Montanawhere
theyre fully protectedbecause they werent reintroduced.
I think its because people have learned how to live with them, and
people heard that there were control measures if they needed them, and
they also respected the wolves. Here [at Yellowstone], it was the Federal
government shoving down this species. So, we felt, lets just be
patient.... [The reintroduction] is all fine and dandy and thats
what happened. Its not a completed success, but its definitely
successful.
