Biodiversity surprise: Scientists puzzled by martens’ return to Isle Royale

Read the full story at Great Lakes Echo.

When it comes to wildlife at Isle Royale National Park, most eyes are on the wolves and moose.

Both are iconic species long studied by scientists and long sought for viewing by visitors to the isolated spot in Lake Superior. And now, after a three-year study, the National Park Service is starting to implement a 20-year plan to restock wolves on the island to help restore a predator-prey balance with moose.

But the 17 other mammal species on the island draw far less scientific and public attention although other species have disappeared, such as the Canada lynx and woodland caribou.

Another one that had been wiped out – the American marten – is back and drawing attention from National Park Service and University of Wisconsin Madison researchers.
