King, Santa Catalina Island Conservancy, unpubl. Recent estimates indicate that the probability of extinction in the next 50 years is <5% for each of the four Island Fox subspecies listed as endangered under the US Endangered Species Act (T. Finally, Island Foxes do not meet the criteria for E, quantitative analysis. The total range for the species is about 9,000 kmĀ², and the number of locations (considering past and future potential threats) is 1,000 and number of locations is >5. Four subspecies experienced declines in the 1990s, but have since increased significantly, to near pre-decline numbers. In regard to criterion A, population reduction, the species has not experienced a population reduction in the past 10 years or three generations. The species meets none of the criteria for the threatened categories (Critically Endangered, Endangered or Vulnerable). The Red List Status for the Island Fox is currently assessed as Near Threatened (it almost qualifies as threatened under criteria B1a and C2a). The total population of mature individuals increased from 4,000 in 2011 and annual survival rates are above 85%. However, all four subspecies have since recovered to or are approaching recovery to pre-decline population levels, due to the success of aggressive recovery actions such as captive breeding and reintroduction, relocation of Golden Eagles, and vaccination against canine diseases. Four Island Fox subspecies suffered catastrophic population declines in the mid-1990s, after which they were listed as Endangered under the U.S Endangered Species Act. The Island Fox is restricted to six of the California Channel Islands off the coast of southern California, USA.

After 4 of 6 subspecies suffered catastrophic declines due to novel predators and disease, mitigation measures have been immensely successful and these 4 populations have returned to or are approaching pre-decline levels. The future prognosis for island foxes is however significantly improved. The working group report that for both kit foxes and swift foxes, habitat continues to be lost and remaining habitat is increasing subject to degradation, fragmentation, and incompatible uses. Island, Kit & Swift Fox Working Group - Brian Cypher and Donelle Schwalm are the coordinators of the Island, Kit & Swift Fox Working Group.
