英文摘要	Limited information is available on whether San Joaquin kit fox (Vulpes macrotis mutica) use below grade passages, design parameters that might facilitate their use, or what rate of passage is needed to offset habitat connectivity losses. This final report details four field studies conducted between September 2007 and January 2010. Swift fox (Vulpe velox) were studied in Colorado and South Dakota and desert kit fox (Vulpes macrotis arsipus) were studied in California. The aim of these companion studies was to investigate the movements and crossing behavior of swift and desert kit foxes around four-lane highways. The four-lane highways in our study areas were generally not a barrier to movement of swift fox and desert kit fox. Small sample sizes of fox crossings at monitored culverts prevented the ability to determine optimal crossing structure design for San Joaquin kit foxes. Nonetheless, some general principles with regard to design of wildlife crossings can be used as guidelines for this species. The best practice would be to install as many culverts or crossing structures as possible within San Joaquin kit fox range and where local habitat conditions are favorable.
