![]() ![]() ![]() Fortunately, island fox species are recovering due to managed conservation efforts since 2006 to (1) translocate golden eagles from the island to the mainland and (2) remove feral pigs from the island. Introduced feral pigs on the Channel Island of California prompted mainland golden eagles to expand their range to the islands, and their predatory presence nearly drove the channel island fox extinct. ![]() The predatory habits of the Golden Eagle, however, have threatened the recovery/status of other endangered species, including the channel island fox. Although the IUCN lists the Golden Eagle as a species of "least concern" globally, the species receives legal protection in the United States from the Bald and Golden Eagle Protection Act. Recovering these populations of ecosystem engineers helps support other species. Beavers once supported a widespread pond ecosystem in the Western US, but were hunted out of many places by the fur trade. Palaeocastor may be gone, but some of its relatives remain. Due to legal protection from hunting and at least 10 reintroductions starting as early as 1922, the Eurasian beaver now has a population that exceeds 600,000. The Eurasian beaver (Castor fiber) was once widespread in Europe and Asia but by the early 20th century was estimated to be less than 1200 individuals. A living relative of Palaeocastor, the Eurasian Beaver, is a conservation success story. Golden Eagle (1) vs Palaeocastor fosser (5) - Palaeocastor is an extinct beaver that lived in the North American badlands over 20 million years ago they never overlapped with humans. ![]()
