Superintendent: No wolves to be brought to Isle Royale for now, despite population decline

TRAVERSE CITY, Michigan — No additional gray wolves will be transplanted to Isle Royale National Park for now, the park's top manager said Wednesday, despite concerns that the Lake Superior island chain's dwindling and inbred population might not survive much longer.

After consulting with experts and reviewing comments from the public, Isle Royale Superintendent Phyllis Green said staffers will develop a management plan that considers the wolves' long-term survival prospects and their interactions with moose. The two species' predator-prey relationship is the subject of one of the world's longest scientific studies of its type, now in its 56th year.

It will take about three years to craft the plan, which also will focus on park vegetation and the effects of climate change, Green said. Officials could reconsider augmenting the wolf population if gender imbalance prevents them from reproducing or if moose begin overbrowsing trees and bushes, stripping them of leaves and needles.

Michigan Tech Wolf-Moose Study Named to Michigan Environmental Hall of Fame | Michigan Tech News

Michigan Technological University’s Isle Royale wolf-moose predator-prey study has been elected to the Michigan Environmental Hall of Fame. John Vucetich, associate professor of wildlife ecology in Michigan Tech’s School of Forest Resources and Environmental Science (SFRES), will represent the research project at an induction ceremony at the Gerald R. Ford Presidential Museum in Grand Rapids, Mich., on April 10.

Ten individuals and organizations will be honored at the ceremony.

"For more than 50 years, the wolves and moose of Isle Royale have been teaching us –all of us—about nature's intricate and interconnected ways,” said Vucetich. “They've been offering vital clues about how we can best relate to the natural world around us. It's a great honor to accept this recognition from the Michigan Environmental Hall of Fame on behalf of the wolves and moose of Isle Royale."

Most Michigan Voters Favor Wolf Hunts

Most Michigan residents say they favor a limited hunting season for wolves, according to a new poll.

The survey conducted by the Lansing-based polling firm Marketing Resource Group, shows that 68 percent of Michigan voters support legislation that would allow for a limited hunting season of wolves in the state.

The strongest support for the legislation is in northern Michigan, where 81 percent of voters agree that the wolf population needs to be controlled.

Metro Detroit and the Cadillac and Traverse City area are the least supportive, with 63 percent and 64 percent support, respectively.

Are the Wolves of Isle Royale Going Extinct?

Ecological challenges occurring on Isle Royale in Lake Superior have made international news. On February of this year, the prestigious international science journal Nature ran a story with the headline: “Iconic island study on its last legs.” The headline referred to ongoing studies begun in 1958 that followed the ecological interdependence between moose, wolves and even balsam fir trees on the isolated island.

Claimed by Michigan, the wilderness island is 45 miles long and about 9 miles wide. Its area of 893 square miles is large enough to sustain its own populations of moose, wolves, foxes, rabbits and other mammals. Vegetation is typical of a boreal forest, with balsam fir a dominant species, along with spruce, cedar, aspen and other tree species. For years wolves, moose, and the plants eaten by moose, have been in a relatively predictable balance.

In 2008 there were 700 moose and 23 wolves on Isle Royale. In 2013 there were 975 moose and only eight wolves. In five years the island had lost 63 percent of its wolves and those that remained had not been breeding, even though a number of females were available.

Moose prosper while wolves struggle on Isle Royale

Wildlife researchers who spent the winter on an island in Lake Superior report that Isle Royale's moose population is booming while wolf numbers remain near an all-time low.

Moose have roughly doubled in the past three years, Michigan Technological University biologists Rolf Peterson and John Vucetich said in a blog post.

The two spend seven weeks every winter on the 45-mile-long island monitoring wolves and moose — both by foot and by air — in one of world's longest continuous studies of predator-prey relationships.

That relationship has tipped clearly in favor of moose, whose population the biologists said has been increasing at an annual rate of more than 20% in each of the past three years.

The latest population figures and a host of other data will be released — probably next week, Peterson said. A year ago in their last report, Peterson and Vucetich counted 975 moose from their winter observations.
