Isle Royale National Park is another paradise of unspoiled nature.

Three Michigan men have been charged with causing a wildfire that burned six acres and damaged Isle Royale National Park, a remote, rugged archipelago in Lake Superior, in 2022, the authorities said.

But on the Isle Royale National Park near Michigan’s border with Canada, balsam firs were being devoured.

Scientists believe the island’s first moose swam to Isle Royale around the turn of the 20th century.

The trends appear to justify federal officials’ 2018 decision to airlift mainland wolves to Isle Royale, the researchers said, arguing that the predators’ return is helping rebalance an ecosystem knocked off-kilter as their number dropped to just two.
