In September 2011, we initiated a 2-year “camera trap” mammal survey in the Greater Oak Flat Watershed near Superior, Arizona. Our survey area covers a total of 6,475 ha. The area surveyed is primarily a mixing zone of upper Sonoran Desert and interior chaparral, with influences from the Madrean vegetation community. Elevations range from 1150 to 1450 m. Ten cameras were deployed in early October of 2011 and information was gathered and analyzed from that date to April 2012. We located cameras primarily in riparian and xero-riparian drainages. Locations were chosen as logical wildlife corridors to obtain a sampling of wildlife while allowing relatively easy access to cameras for data collection. To date, we have identified 13 mammalian species, including bobcat (Lynx rufus), ringtail (Bassariscus astutus), and coati (Nasua narica).
