I am a wildlife ecologist for H. T. Harvey & Associates. My primary focus is studying the Endangered San Joaquin kit fox (Vulpes macrotis mutica) and the red fox (V. vulpes). I am interested in all foxes and carnivores, and have a special interest in compiling a list of mainstream scientific journal references for the endangered Island Fox, which has six recogized subspecies:
Endangered:
1. San Miguel Island fox (U. l. littoralis)
2. Santa Rosa Island fox (U. l. santarosae)
3. Santa Cruz Island fox (U. l. santacruzae)
4. Santa Catalina Island fox (U. l. catalinae)
Species of Concern:
1. San Clemente Island fox (U. l. clementae)
2. San Nicolas Island fox (U. l. dickeyi)
2001 Federal Register / Vol. 66, No. 237, pages 63654 - 63665
2004 Federal Register / Vol. 69, No. 044, pages 10335 - 10353
2004 Federal Register / Vol. 69, No. 194, pages 60134 - 60138
