Great Lakes gray wolf on Wisconsin’s Stockton Island.

An extensive camera trap survey of the Apostle Islands in Lake Superior has revealed a great diversity of carnivorans, including gray wolves and American martens. These islands, located just off Wisconsin’s Bayfield Peninsula, are among the few places left in the Eastern and Midwestern US that still retain an intact predator guild, and because all but one of the islands is protected as a national lakeshore, these islands will be protected from most exploitative development.

I love living in a country that still has room for wolves and wild places. Our natural heritage is every bit as important to us as a nation as our constitution and rule of law, and it should be protected with the same ferocity that we use to protect our republicanism.

Also of importance is the Great Lakes wolf in the trail camera capture that was part of the survey. This wolf looks to be one of wolves with some amount of coyote introgression. Great Lakes wolves can have quite a high amount of coyote ancestry, and the earliest estimated introgression of coyote genes into gray wolves that has been documented is from these Great Lakes wolves. This introgression happened as early as 963 years ago.

Coyotes and gray wolves are found on the islands now, and one wonders if they still occasionally interbreed. The Great Lakes are also the region that experienced the beginnings of the hybrid swarm we call the Eastern coyotes.

So these islands could be a new Isle Royale from which to study the new and evolving wolf and coyote of North America.
