I believe (as do quite a few others) that all non-boreal Red Fox are
"introduced" in the USA.

e.g.

http://www.ifaw.org/ifaw_international/save_animals/other/red_fox.php

and

http://www.wildlifeonline.me.uk/red_fox.html

For more detail see the paper "A Review of Native and Nonnative Red
Foxes in North America"

<http://www.jstor.org/pss/3784493>

This is a pretty good review in the status of Red Foxes (including
their spread into the West over time).
You can find the whole paper here. It's a non-technical read.

<http://www.wildcru.org/aboutus/people/kamler_pdfs/2002-4.pdf>

The authors are very skeptical that Vulpes vulpes cascadiensis (or
Vulpes fulva cascadiensis depending on your taxonomy!) still exists as
a derivative of the original native boreal Red Foxes.

Has anyone here personally seen a Red Fox they believe was a
cascadiensis?

Or know of any DNA work that's been done with cascadiensis?

Thanks,
Kevin
