San Miguel Island Fox Population Recovers Significantly After Conservation Efforts
The San Miguel Island fox population, once critically low at 15 individuals, has rebounded to approximately 322 by 2024. This recovery is attributed to comprehensive conservation strategies implemented on San Miguel Island, located off the coast of Southern California. These efforts included the removal of golden eagles, which preyed on the foxes, and the eradication of feral pigs that provided a food source for the eagles.
