What I find interesting is that an ice bridge has formed again between the island and the mainland - in fact, Lake Superior was 94% covered by ice on Februrary 13! I think it would be really cool if some wolves from Minnesota or Canada made their way to the island on their own, although scientists say it is a slim chance. There is always the possibility that some of the island's wolves will migrate back to the mainland as well.
Moose populations on Isle Royale have been increasing to the point that they are changing the vegetation left from their browsing, and there aren't enough wolves to hold their populations in check. If the wolves go extinct, the moose may eat themselves to death.
