once every three working days. Information on each location of a frog was recorded, along with the species and sex if possible. Frogs or toads that could not be identified to species were also counted and included in the total number of frogs found. Frogs and toads were removed from the road after identifying them so as not to count them on subsequent sampling days. Known hot spots were located at four different locations on the surveyed roads. A "hot spot" was an area with a consistently greater range of frog diversity and a noticeably higher number of amphibian fatalities than other roads. Hot spots were located in areas where roads crossed through wetlands. The identified hot spots were surveyed at dawn. These surveys consisted of walking along the shoulder of both sides of the road for a defined distance and recording all frogs founds there. The average length of the four transects was 225 meters. The study is still on going; however, we have detected a definite pattern in which species are killed by cars along the highways. We compared the pattern to known dispersal distances, as obtained from scientific literature, with the patterns of frog and toad deaths in our census. At the hot spots there is
