Pendulum appears to swing toward wolves, away from moose, at Isle Royale NP

Too little food and too many ticks are adversely impacting the moose population at Isle Royale National Park, though a seemingly increasing wolf population could begin to play a role in producing a more balanced number of moose on the island.


This spring Michigan Tech researchers found that "most balsam fir saplings had been browsed so severely that they had either been killed or left with only a few green branches at the west end of the island. Researchers also found the bodies of 13 moose, when in a regular year they would typically find only one to two starved moose."
