Restored wolf population save Isle Royale island chain's struggling ecosystem

Gray wolves are thriving at Isle Royale National Park after being nearly driven to extinction.
The wolf population has rebounded to 31 wolves this year, up from just 2 wolves in 2019, and appears to be forming three packs.
The restored wolf population is helping reduce an overpopulation of moose that were starving due to lack of food.
The moose population has declined by 54% from around 2,000 in 2019 to roughly 967 this year.
The decision to bring wolves from the mainland to the island has helped restore balance to an ecosystem that had been disrupted by the wolves' long decline.
