The National Park System is an incredible reservoir of wildlife, from charismatic animals such as grizzly bears, bison and wolves, to animals such as moose, and pronghorn and sea turtles that, while not usually labeled as charismatic, are indeed just that.   Wolves certainly fall under the charismatic megafauna classification. They're majestic and mystifying, and perhaps even lend some romanticism to your backcountry adventures if you are lucky enough to hear a pack howling in chorus after sundown.    While it’s well-known that Yellowstone National Park and Isle Royale National Park have wolf populations, you might not know that Voyageurs National Park also has a resident population of the predators. To learn more about the wolves at Voyageurs National Park and their behavior, we’re joined today by Dr. Thomas Gable, the project lead for the Voyageurs Wolf Project.
