The ice bridge to Isle Royale has formed. See our post here.

Original post: January 9, 2014

Wolves first came to Isle Royale in Lake Superior by crossing an ice bridge in the late 1940s, but these ice bridges have not been forming as often in recent years and the wolf population on Isle Royale has been suffering as a result.

Why are moose populations declining?

All across North America, something is happening to the moose.

From British Columbia to New Hampshire, moose populations are thinning out, and no one has been able to point to a good, clear reason why.

For the status of moose here in Michigan, we turned to Rolf Peterson, Professor at Michigan Technological University. He joined us from Houghton.

Bad weather hampers Michigan moose population survey

MARQUETTE, Mich. (AP) - Poor weather is making it hard for the Michigan Department of Natural Resources to count the number of moose in the Upper Peninsula.

The DNR surveys the moose population every two years. The census is based on the number of animals spotted by crews flying over prime moose range in Baraga, Iron and Marquette counties.

It's typically done in January, when the ground is covered with snow. That makes it easier to see the animals.

VIDEO: Picking apart a dead moose on Isle Royale

It's not as gross as it sounds. And if you heard yesterday's report from Rebecca Williams, it really does sound gross.

The wolf-moose research project on Michigan's Isle Royale National Park is in its 54th year.

A big chunk of their research goes into tracking down dead moose - bones and carcasses - around the island.

From these remains the researchers can pick apart the status and overall health of the moose population. And understanding moose is important to wolf research, since the wolves eat the moose.

It's like understanding the overall quality and quantity of food available at the grocery store. If there's good, abundant food available, you'd expect things to be good. If not, well - you get the picture.

When Rebecca Williams and I arrived at the Daisy Farm campground on Isle Royale, we were met by Rolf Peterson in his boat.

He said he'd just heard of a dead moose on Caribou Island and asked whether we would like to go see it with him.

A stroke of luck. We'd traveled by plane, car, and boat to get here, and here was our chance to see Peterson in action.

Here's a video of our trip with him. Is ripping the skull off a dead moose gross? I didn't think so, but you can be the judge.

So, what did you think? Vote by typing "gross" or "not gross" in the comment section below.

Moose hunt opposed by Chippewa tribe in the U.P.

The DNR will soon decide whether a limited moose hunt will be held in Michigan.
MI DNR

It's up to the Michigan State legislature to determine what game is available for hunting in Michigan.

In late 2010, the legislature opened up the possibility of a moose hunt in Michigan.

They charged the Moose Hunting Advisory Council with developing recommendations on whether or not a moose hunt should be conducted. (You can let them know what you think by dropping them a line - moosecomments@michigan.gov).

The council is expected to present their report to the Michigan DNR's Natural Resources Commission next Thursday (September 15). The Associated Press reports that the Moose Hunting Advisory Council will recommend a moose hunt of 10 bull moose.

The NRC will take the recommendation and decide whether a hunt will occur.

But ahead of all that, the Inland Conservation Committee with the Sault Ste. Marie Tribe of Chippewa Indians voted to oppose the hunt.

Here's part of a statement from the tribe:

At its Aug. 1 meeting, the committee cited biological concerns of a hunt’s impact on a fragile and uncertain population of 433 moose. The proposed hunt would take 10 bull moose in the fall after the rutting season, according to news accounts. The Department of Natural Resources was officially notified of the decision last week.

The statement says "under the terms of the 2007 Inland Consent Decree, the committee's opposition effectively ends Michigan’s bid for a moose hunt, for now."

A spokeswoman for the DNR said the tribe's position will have no effect on the report going to the Natural Resources Commission next week.

If the NRC votes to establish a moose hunt in Michigan, the question of whether or not the tribe's opposition prohibits a hunt will have to be answered.

Isle Royale's wolves to go extinct?

The wolves of Isle Royale National Park in Lake Superior could be in trouble.

For 53 years, researchers from Michigan Tech have been studying the island’s wolf and moose populations.

This year... they found there are fewer wolves – just 16. And only a couple of females that can still have babies. Rolf Peterson has been studying the wolves for more than four decades.

He says it's not clear why some of the wolves are dying.

"In late 2009, six of the ten females we had in the population died. That was just an unusual, presumably a fluke. Only one of the females was radio collared and she died in a very unusual way, she died giving birth."

He says the outlook for the existence of wolves on Isle Royale is uncertain.

"It could be just a little hurdle they have to jump through. It also could mean the beginning of the end if those one or two females should die without giving birth to a female. And if neither of the two pups we thought we saw this year are female, then that's it. The population would go extinct because there are no females."

At this point, he doesn't think people should intervene. But he says there could come a point where the National Park Service might introduce new female wolves from the mainland. Peterson says the males on the island would readily accept new females if the existing females die.

The wolves keep the island's moose in check. The research team has found that the moose population is currently around 500 animals. If the wolves go extinct, Peterson says the moose would be in trouble too.

"They'd increase to the point where they'd starve to death catastrophically."

Peterson has spent most of every year for four decades living among the wolves and moose on the island with his wife Candy.  But he says there's still plenty to be discovered.

"Almost everything that happens there surprises me. We're almost unable to predict the short term future. I guess the resiliency of wolves in general does usually surprise me. I wouldn't be the least bit surprised if they pulled out of this one. But exactly how they're going to do it is what's fascinating."
