US EditionResearchers say remote Lake Superior island’s wolves are thriving as packs prey on moose
Researchers estimated 37 wolves and 524 moose, with wolves killing nearly a quarter of the herd and no calves seen for the first time in decades.
- Researchers from Michigan Tech University released a report Monday showing Isle Royale's wolf population reached 37, the highest count since the late 1970s, while the moose population dropped 75% from 2,000 in 2019 to 524.
- A team led by Michigan Tech conducted the survey from Jan. 22 through March 3. Scientists braved wind chills of minus 50 degrees Fahrenheit, with clear skies enabling exceptional observations of the wolf packs.
- Researchers estimated wolves killed nearly a quarter of the moose population over the last year. For the first time in almost 70 years, scientists observed no moose calves during the winter survey.
- The National Park Service previously forced researchers to evacuate the island during 2024 after unsafe ice on Lake Superior halted surveys. Past obstacles included the 2021 pandemic, making this year's successful survey a significant achievement.
- Scientists plan to conduct summer research on Isle Royale to determine how burgeoning wolf packs can maintain ecosystem balance. The island serves as a natural laboratory offering scientists rare observation opportunities largely free from human influence.
