We used trapping, track plates, and remote cameras to survey the distribution of gray foxes (Urocyon cinereoargenteus), coyotes (Canis latrans), and bobcats (Lynx rufus) in southern Illinois during 2005-07. Gray fox detection rates were low for all survey techniques when compared to more abundant mesocarnivore species. We captured 9 gray foxes and 21 bobcats in 7,729 trap-nights and 6 coyotes in 1,416 trap-nights. Track plates (n = 883 survey-nights) resulted in the detection of 6 gray foxes, 1 bobcat, and 1 coyote. Cameras (n = 953 survey-nights) resulted in the detection of 4 gray foxes, 5 bobcats, and 4 coyotes. Although the relative effectiveness of detection methods varied by species, our data are generally in agreement with other survey methods that indicate the relative scarcity of gray foxes compared to bobcats and coyotes in southern Illinois.
