Aleutian Cackling Goose: In 1975, fewer than 800 Aleutian cackling geese remained; fox removal and habitat protection helped the population rebound to around 200,000, and regulated hunting later returned

Fewer than 800 Aleutian cackling geese remained in 1975, with the birds restricted to a single rocky island in Alaska after introduced Arctic foxes destroyed nesting colonies across the Aleutian Islands. Fifty years later, predator removal, the creation of protected wetlands in California and coordinated management along the Pacific Flyway have helped the population recover […]

Fur traders introduced Arctic foxes across Alaska’s Aleutian Islands to produce pelts; by killing seabirds, the foxes helped turn lush grasslands into tundra

The foxes reduced seabird populations, which meant less nutrient-rich guano reached the islands. Arctic foxes introduced to more than 400 Alaskan islands for fur changed far more than the local wildlife. According to a study published in journal Science, by preying on seabirds, they disrupted the flow of nutrients from the ocean to land and […]
