ISLE ROYALE NATIONAL PARK--   An Upper Peninsula wolf has joined 14 others on Isle Royale National Park.

The 70-pound, three-year-old male was captured on the mainland last week and flown by sea plane to the moose-laden island. It marks the second year of the National Park Service’s efforts to restore predation to Isle Royale after wolf numbers decreased to only two. Since last September 12 other wolves were brought from Ontario, Canada, Minnesota, and a Canadian island.

HOUGHTON, MI--   A study of the predator-prey relationship between moose and wolves on Isle Royale has been inducted into the Michigan Environmental Hall of Fame.  

John Vucetich is director of the 56-year-old study and an associate professor at Michigan Technological University.  He says the study was begun to answer questions about how predators affect prey at a time when the public viewed wolves in a negative light.

Park won't add wolves to Isle Royale pack... yet

ISLE ROYALE NATIONAL PARK (AP)--   The superintendent of Isle Royale National Park says officials have decided not to bring more wolves to the Lake Superior island chain for now to prevent their dwindling population from dying out. 

Phyllis Green said Wednesday that after consulting with experts, she's convinced there is time for a comprehensive study of the role that wolves and moose play in the park's ecosystem.

She said officials could reconsider importing wolves if gender imbalance prevents the island population from breeding or if moose overbrowse park vegetation.
