We performed a pilot study to determine whether camera traps were an effective means for establishing a baseline of species richness, distribution, and abundance at a state natural area in San Antonio, Texas, that has never undergone a full wildlife census. We measured 1,714 trap events and 18 wildlife species. We calculated low species diversity and evenness; and white-tailed deer (Odocoileus virginianus), coyote (Canis latrans), and gray fox (Urocyon cinereoargenteus) were the most abundant species. However, the invasive exotic feral pig (Sus scrofa) was also recorded in high densities. The results of this camera study illustrate the ease with which camera traps can be used to collect baseline data, by undergraduate students in the case of this study, which can provide vital field-based research experiences for students and produce much needed wildlife occurrence data for federal or state agencies in designing management plans for species of concern, such as the feral pig, or for threatened or endangered species.
