Michigans Isle Royale is down to just a few wolves, leaving moose to eat the park bare.

Taylor Hill is TakePart's associate environment and wildlife editor.
In 2009, there were 24 wolves left in Michigans Isle Royale National Park. By 2013, there were nine.
This year, there are only three.
This is worse than I thought the worst-case scenario for the wolf population would be, said wildlife ecologist Rolf Peterson, one of two researchers at Michigan Technical University who conducted this years field study, in February.
They recorded only three wolves on the island: two adults and one nine-month-old pup, traveling together. The pup did not look healthy, said Peterson, with a hunched back and a curlicue for a tailmost likely the result of third-generation inbreeding.

introduce some new genes into the population of wolfs. They decided years ago to leave it to nature.

Isle Royale is in the midst of Lake Superior. Access only by boat (sometimes by plane) if they let you go there. It is one of the more pristine of the National Parks, mainly because of its inaccessibility. It is the only National Park in Michigan.

When camping there back in the 80s a wolf walked right up to our campsite checking us out. We walked right past moose along the trail.
It is a great place to hike.

(5,075 posts)5. The moose - wolf relationship on Isle Royale has always been in flux.
Then something remarkable happened. In 1997 a wolf from Canada walked across the frozen ice bridge that had formed that winter. We had known his identity all along - he was the old grey guy, alpha male of Middle Pack during their most successful years. He was physically large and light in the color of his coat (see image below).
Through the analysis of DNA obtained by collecting scat, the old grey guy became wolf no. 93. And through that genetic analysis, we learned that no. 93 was not a native Isle Royale wolf, but instead an immigrant from Canada. He represented a badly needed infusion of new genes. Within about five years of his arrival, the inbreeding coefficient for Isle Royale wolves dropped well below 0.2 (See graph below).

We spent a total of 5 days on the Island. No wolves but lots of evidence of moose.
