Wolf Population Boom on Isle Royale, Moose in Crisis

0:00It's April 27. From your city to your ears, this is Durham News today, powered by AI. I'm Cory with the story. Wolves are booming on Isle Royale, that remote island in Lake Superior serving as a prime natural lab for predator prey dynamics. Latest survey clocks the Wolf Count at 37, the highest since the late 1970s and up from 30 last year. But the moose, their main meal ticket, are taking a brutal hit, dropping to just 524. Researchers from Michigan Tech pulled off the winter survey from January 22, through March 3, after years of setbacks like the pandemic. Shut down, sketchy ice for ski planes, and even a pilot's medical emergency. These counts have tracked population since 1958, with minimal human interference on the 207 square mile island. The moose plunge, marks a 75% crash from 2000 back in 2019, with wolves likely knocking off nearly a quarter last year alone.

1:01For the first time in nearly 70 years, zero calves showed up in the survey, signaling real trouble for the herd's future. Teams braved windshields down to minus 50 degrees Fahrenheit for killer sightings, spotting wolves on almost every flight and catching packs in. Action from courtship to hunts. Class inbreeding had tanked wolf pups, but numbers are rebounding strong now. Scientists gear up for summer field work to see if these swelling packs can keep the ecosystem in check, without wiping out the moose for good.
