Wisconsin and Michigan wolves

From ANIMAL PEOPLE, March 2006:

The heavily publicized Yellow-stone region wolf wars have
parallels in the upper Midwest, the one part of the Lower 48 states
where wolves were never killed out.
After wolves gained Endangered Species Act protection in
1974, the Wisconsin wolf population continued to struggle for a
decade, but now has increased to as many as 455, a fourfold
increase in 10 years, coinciding with abundant deer and falling
numbers of human deer hunters.
Wolves in the upper Midwest in April 2003 were federally
downlisted from “endangered” to “threatened,” but the “endangered”
status was judicially restored in January 2005. In the interim,
the Wisconsin Department of Natural Resources killed 70 alleged
“problem” wolves.
Humane Society of the U.S. conservation consultant Karlyn
Atkinson Berg told Lee Berquist of the Milwaukee Journal Sentinel in
February that Wisconsin wolf numbers warrant downlisting.
“Unfortunately,” Berg said, “the history of wolves is that
if a wolf kills one sheep, then people want to kill 100 wolves.” she
said. Farmers, Berg observed, are “never required to exercise good
husbandry,” to prevent predation on unattended animals.
There are now about 405 wolves on the Michigan Upper
Peninsula, say state biologists, who believe the Michigan
population has reached the carrying capacity of the habitat.
