Should humans put more wolves on Isle Royale?

Lead in text: 
Times have changed. In Michigan we plan on killing wolves because some feel there are too many. It's a different story on Isle Royale where the wolf population is hanging on by a thread. But because Isle Royale National Park is a designated wilderness area, we, as humans, have pledged not to intervene. So what should we do? The National Park Service has a big decision to make. The folks who have been studying this place for a long time share their thoughts in this op-ed piece.
IN Lake Superior lies a remote island, Isle Royale National Park, 134,000 acres of boreal and hardwood forests where a life-or-death struggle between wolves and moose has been the subject of the world's longest study of predators and their prey, now in its 55th year.

Romeo dies in an old mine: How three Isle Royale wolves died

"Romeo" was eager to mate with other females. He was one of the wolves that died in the mine shaft last fall. He's seen here following a female wolf in 2010.

In the last year, seven wolves on Isle Royale died. The total population is now down to nine wolves.

That's the lowest number recorded by researchers who have been studying the Isle Royale wolf population for the last 54 years. It's the longest continuous predator-prey study in the world.

When Rebecca Williams and I visited Rolf Peterson on Isle Royale last month, we asked him about the die-off.

He told us they didn't know what happened to them, "but we will know," he said.

Well, now they know how three of the seven wolves died. One was a young female wolf.

VIDEO: Picking apart a dead moose on Isle Royale

Wolf biologist Rolf Peterson taking us to the site of a moose carcass on Caribou Island. He and other researchers collect bones from dead moose as part of their research.

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.
