Male wolf relocated to Isle Royale NP found dead; cause unknown with necropsy pending

One of four wolves relocated to Isle Royale National Park this fall as part of a recovery mission for the species in the park has been found dead of unknown causes, park staff announced Tuesday.

Shortly after the male wolf was released on the island its radio collar malfunctioned, transmitting a mortality signal even when remote cameras in Isle Royale showed the animal to be alive. However, late last month the collar not only sent a mortality signal, but also indicated the animal's movements were restricted to a small area.
