This report and the analyses contained within would not have been possible without the concerted and coordinated efforts of hundreds of volunteer roadkill observers over the last 7 years. Through their endeavors, they have collected >50,000 observations of >410 species, representing one of the largest and most comprehensive wildlife monitoring programs in California. Their accuracy rates for species identification are >93% and have measurably high locational accuracy (<+100 meters).
