TRAVERSE CITY, MI (AP)-- Federal officials are taking a closer look at whether to bring more gray wolves to Isle Royale National Park, where only two of the iconic predators remain.
The National Park Service last year began studying how to manage the Lake Superior park's wolf and moose populations over the next 20 years.
But with the wolves on the brink of dying out, the service says Wednesday it will focus on whether to bring more of them to the island in the near term — and if so, how.
Wolves first made their way to Isle Royale from the mainland across ice bridges in the late 1940s. Their population has averaged in the low 20s but has declined steeply in recent years. Scientists say they're needed to keep moose numbers under control.
