Minnesota's wolves needed for ecological balance

A recreational hunt doesn’t follow the DNR’s
stated management plans.

“Despite wins, Minnesota’s endangered species list
up by 180” (Aug. 20, 2013) quotes the Department of
Natural Resources’
Natural Resources’
(DNR) endangered species coordinator as stating,
“We’ve got to learn
“We’ve got to learn
how to manage species on a larger scale.”
Leopold’s trophic cascade concept articulated
emphatically that killing a predator wolf carries
serious implications for the rest of the ecosystem.
Later, that concept was endorsed by former Secretary
of the Interior Bruce Babbitt.
The state’s list of species that have gone extinct and
of those that are endangered and threatening to go
extinct has grown tremendously.

One of the first steps in the large-scale management
referred to by the DNR is to keep in place the vital
assets already provided by nature. This is particularly

A Romanian proverb says, “Where wolves roam,
forests grow.” Having wolves on our landscapes
and ecologically active is vital to maintaining the
natural balance for all wildlife.

There is ample science and thinking that supports
this management strategy, and innovative new ways
to reduce wolf conflicts with livestock, including
nonlethal methods (only 2 percent of the Minnesota
farms in wolf country have experienced wolf problems
with livestock)As far back as the 1920s and ’30s,
University of Wisconsin scientist, ecologist, forester
and environmentalist Aldo Leopold established visionary
wildlife management theories that rightfully viewed
wildlife issues within the greater ecological system
of nature.In 1949, he proposed that a natural predator
such as the wolf has a major residual impact on plants;
river and stream bank erosion; fish and fowl; water
quality; and on other animals. In other words, the
wolf is a keystone species.

The natural benefits of wolves to our complex landscapes

• The presence of wolves helps plants and tree growth by
affecting the browsing behavior of deer, especially along
stream and river banks.

• Groundbreaking work by Oregon State University
professors William Ripple and Robert Beschta in
Yellowstone National Park has shown Leopold’s
principles to be true; the reintroduction of the wolf
improved the Yellowstone River wildlife and ecosystems.

• Their work has relevance in Minnesota. Although
the ecosystems are dissimilar, the wolf still plays
a major role in both places and is Minnesota’s ally to
slow species extinction.

It is unfortunate that the DNR does not treat the wolf
as a valuable asset for the large-scale needs of so
many other species. The DNR proposed to remove
the wolf as a species of special concern the same
year the wolf was removed from the federal endangered
species list.

Yet no baseline population survey was done before the
wolf was proposed to come off the state’s list or before
the hunt. And it’s unclear: Who exactly supports the hunt?
Even before the first wolf hunting and trapping season in
2012, the DNR’s own online survey indicated that a hunt
was opposed by 79 percent of respondents.

If we look at the DNR’s published numbers, our wolf
population is already 25 percent less than it was at
last count in 2008. It had been stable without a hunt
from 1998 through 2008.

Today, we have the lowest number of wolves reported
since 1988. The wolf’s removal from the list of species
of special concern has made it solely a game species
and not in the category of a nongame wildlife species
to be protected.

With so many other species whose existence depends
on the presence of the wolf, it behooves the DNR to
follow its own Wolf Management Plan. That plan’s
stated goals are to ensure the long-term survival of the
wolf in Minnesota and to resolve conflicts between
wolves and humans.

Even without a hunt, wolves are killed that are perceived
to be a threat. Nor is there a plan to support nonlethal
prevention methods that work for reducing wolf-livestock
conflicts. The rare and first Minnesota wolf-human attack
aside, the wolves that will be killed in another hunting
season are random and not necessarily causing problems.

Last year, of the 413 wolves killed, 240 were juveniles.
These young wolves had survived the high mortality
pup stage and were growing to the reproductive age
