ISLE ROYALE NATIONAL PARK--   Researchers are releasing summer predation data from Isle Royale National Park. 

National Park Service, State University of New York – College of Environmental Science and Forestry and Michigan Technological University biologists monitored wolves introduced to the island in the fall and winter of 2019. It’s the first time wolf predation has been studied during snow-free periods.

HOUGHTON, MI (AP)--   The longtime superintendent of Isle Royale National Park is retiring. 

Phyllis Green stepped down Friday as head of the remote park in northwestern Lake Superior. She held the position for 18 years. It was her final stop in a 41-year career with the federal government that also included posts with the U.S. Forest Service.

At Isle Royale, Green oversaw the first stages of a continuing project to restore the gray wolf population by relocating animals from the mainland.

ISLE ROYALE NATIONAL PARK, MI--   Isle Royale National Park’s wolf population is now 17.

Two males and one female were moved from the Upper Peninsula to the park September 13, bringing the number to nine males and eight females. A fourth wolf was moved to Isle Royale, but its collar sent out a mortality signal soon afterward. Officials say the stresses of being captured, tranquilized, and moved affects each wolf differently.

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.

ISLE ROYALE NATIONAL PARK--  Isle Royale officials are seeking public comment on the park’s draft Cultural Resource Management Plan and Environmental Assessment. 

The purpose of the plan is to develop a strategy for managing the non-wilderness cultural resources of the park.

ISLE ROYALE NATIONAL PARK, MI--   One of the wolves transported to Isle Royale National Park in February has died. 

The National Park Service says in late March it received a mortality signal from a black-coated male trapped in Ontario, Canada. Personnel had to wait until the park reopened for the 2019 season to investigate.

ISLE ROYALE NATIONAL PARK (AP)--   Moose are thriving at Isle Royale National Park, but many trees are paying a heavy price. 

A report released Tuesday estimates there are 2,060 moose at the wilderness park in northwestern Lake Superior. That's the highest number since 1995, when the population exceeded 2,400. The population fell to about 500 over the next two years because of harsh winters and a shortage of food.

ISLE ROYALE NATIONAL PARK--   Officials who relocated seven wolves to Isle Royale National Park are calling the effort a major success.

Six wolves from Canada’s Michipicoten Island and one from the Ontario mainland were captured, checked and moved to the park Friday through Sunday. The Michipicoten wolves were in danger of starvation because they had run out of prey.

Of the seven wolves, three were female. One of them may be pregnant. If she were to give birth this spring, it would be the first pups born on Isle Royale since 2014.

ISLE ROYALE NATIONAL PARK--   A U.S.-Canadian team has successfully relocated about half a dozen gray wolves to Isle Royale National Park. 

One of two private organizations helping to fund the effort reported Sunday on its Facebook page that the relocation involved six wolves from a second Lake Superior Island in Canadian territory and one from the Ontario mainland.

The National Parks of Lake Superior Foundation said Sunday that the animals were captured, vet checked and transported over the past couple days.

ISLE ROYALE NATIONAL PARK--   Wildlife officials are trying to move up to six starving wolves to Isle Royale National Park, where moose are abundant. 

The National Parks of Lake Superior Foundation is working with the International Wolf Center to move the remaining wolves from Michipicoten Island in northern Lake Superior over the next four days. The wolves are at risk because their main winter prey – caribou – are now gone.
