Federal officials have tentatively decided to transport 20-30 gray wolves to Isle Royale National Park in Michigan over the next three years to replenish a population that has nearly died out because of inbreeding and disease.
The National Park Service said Friday it will make a final decision in 30 days, after the public has had an opportunity to review a new environmental statement that endorses the restoration plan.
Wolves made their way to the Lake Superior island in the late 1940s. Since then, they have played a valuable role in keeping the moose population in check and have become a cherished symbol of the remote wilderness outpost.
But the wolves' numbers have fallen drastically in recent years. Only two are believed to remain, posing a danger of moose overpopulation.
