Amargosa Vole Disease Monitoring


Amargosa River at Tecopa

The Amargosa vole is a subspecies of the California vole and is endangered both federally and by the state. This subspecies only exists in the Mojave Desert within the wet meadows and marshes of the Amargosa River drainage in Inyo County. Originally, habitat loss and invasive species, most notably the house mouse, threatened the persistence of this vole subspecies. However, recent discovery of a detrimental disease affecting many individual voles throughout the population presents yet another developing threat to this rare rodent. IERC is assisting the laboratory of Dr. Janet Foley at U.C. Davis to study this emerging disease threat by screening both healthy and clinically diseased individuals for this disease caused by mite infestation.
