Abstract: We conducted auditory surveys to further document the distribution of Great Basin Spadefoot (Spea intermontana), Western Toad (Bufo boreas), Wood Frog (Rana sylvatica), Pacific Chorus Frog (Pseudacris regilla), and Columbia Spotted Frog (Rana luteiventris) populations in the Cariboo Region. Surveys were conducted by Ministry of Environment (MoE) biologists, BC Conservation Corps (BCCC) employees, members of the Canoe Creek Indian Band (CCIB), and volunteers. We conducted a total of 330 auditory surveys to detect calling male Great Basin Spadefoots and other amphibians at 202 different sites between May 2 and July 7, 2007. Sixty-one of 202 sites surveyed had 1 or more target amphibian species present. We detected spadefoots at 45 sites, including 6 ponds with other species present. Spadefoots were detected calling from May 02, to June 27, 2007. We estimated the number of spadefoots detected at a single site between 1 and 25 individuals. We also detected Western Toads, Wood Frogs, and Pacific Chorus Frogs during this period. We did not detect Columbia Spotted Frogs on any surveys.
