Overview

• 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.
