Eight sites were monitored, with the remaining four cameras held in reserve to replace cameras that needed maintenance or had failures. From January 2010 the images were downloaded every 20–30 days. None of the cameras were baited. Timing of camera placement varied on results obtained per location (Table 2).All cameras except for one were placed on tree trunks, ranging in height from 50 cm to 150 cm above the ground, and in one instance on a horizontal branch looking down into a cave (Site 6).The camera at Site 8 was placed on a metal pole left over from archaeologi- cal excavations inside the cave. Data are pre- sented as total number of images per 100 days (Table 2).

RESULTS The cameras recorded 10 carnivore species from the families Felidae (3), Viverridae (2), Mustelidae (2), Hyaenidae (1), Canidae (1) and Herpestidae 2010 2010 2010 2010 2010 2011 2011 2011 (game trail) (cave) (game trail) (game trail) (game trail) (cave) (near water) (cave) images trap days* (1).
