Feral pigs were eradicated from Santa Cruz Island, facilitating a resurgence in fox populations. With bald eagles no longer in the area, golden eagles preyed on the island's foxes. In response, conservationists captured the golden eagles and reintroduced the native bald eagles. A captive breeding initiative safeguarded the remaining island foxes from predators, resulting in a successful revival of the island's native wildlife and ecosystem.

An ambitious conservation project off the coast of California has helped save the endangered Santa Cruz Island fox from near extinction. The rescue effort involved removing 5,036 feral pigs, allowing the native island fox (Urocyon littoralis santacruzae) population to recover from fewer than 100 animals to more than 1,300 across the 96-square-mile island.

In the late 1990s San Miguel Island held 15 foxes, down from about 450; after 44 golden eagles were relocated and 226 captive-bred foxes returned, the island counted roughly 322 in 2024

A species on the brink of extinction needed two desperate interventions—removing an apex predator and breeding foxes in captivity—to climb back from the edge of oblivion.
