Botanical compositions and pH values for pronghorn (Antelocapra americana) and mule deer (Odocoileus hemionus) fecal pellets from the Idaho National Engineering Laboratory Site were different. As there was no overlap between ranges of the herbivores fecal pH values, the fecal pH technique is a valuable tool for distinguishing between fecal pellets of pronghorn and mule deer on the study area.
