HOUGHTON -- During their annual Winter Study at Isle Royale National Park, scientists from Michigan Technological University counted nine wolves organized into one breeding pack and a second small group that is a remnant of a formerly breeding pack.
In the Isle Royale Wolf-Moose Study’s annual report released Apr. 30, 2014, the researchers say that over the past three years they have tallied the lowest numbers of wolves ever: nine in 2011–12, eight in 2012–13 and nine in 2013–14. During the same period, predation rates -- the proportion of the moose population killed by wolves -- also dropped to the lowest ever recorded, while the number of moose doubled, to approximately 1,050 moose.
