Remote Camera Survey for Red Foxes at Crater Lake National Park 2012

Information on red fox (Vulpes vulpes) within Crater Lake National Park consists almost entirely of incidental observations. Infrared remote cameras were deployed at 42 sites baited with scent lures during August and September 2012 for 585 effective trap nights. Camera locations were at elevations above 6000 feet in the vicinity of historical sightings. Red foxes were detected on 11 occasions over 8 nights at 7 sites. Genetic analysis of nuclear DNA from one opportunistically collected fur sample was unsuccessful, preventing definitive determination of the subspecific identity of the sampled fox. However, analysis did identify the composite mitochondrial haplotype ‘A19’, the most common mitochondrial haplotype identified in historical specimens of the Sierrra Nevada red fox (V. v. necator; hereafter SNRF). This is consistent with prior genetic analysis that determined SNRF were present within the park historically. SNRF, with only two known populations consisting of possibly less than 50 individuals combined, is currently under review by the U.S. Fish and Wildlife Service for listing as federally threatened or endangered and has been listed as threatened since 1980 in California.
