Methods
Life forms: carnivores,primates,rodents,ungulates,other large mammals,birds
Sampling methods: no design,automatic cameras
Sample size: 215 captures or sightings
Years: 2013
Days: 42
Seasons: wet or monsoon
Nets or traps: 29
Net or trap nights: 932
Camera type: digital
Cameras paired: no
Sampling comments: "To ensure adequate coverage of the 250 km2 study area, 50 x 0.25 km2 survey cells were sampled"
"A total of 22 passive infra-red triggered digital cameras (12 x Bushnell, 8 x Uway and 2 x Cuddeback) ... were deployed between 16 October 2013 and 26 November 2013"
"Twenty cameras were specifically deployed for mammals, while the remaining two were specifically deployed for birds"
"For mammals, an array of between four and nine cameras was deployed for at least three and up to six consecutive trap nights, except for the period 26 October to 11 November, when all traps were deployed continuously"
"Each camera was deployed to monitor specific habitat types within a 250 m radius of the predetermined survey points"
"Cameras were fastened to tree trunks at 600–800 mm above-ground"
"All cameras were set to record three images per trigger-event, and 30-second delays were programmed between consecutive trigger-events"
In total, "Twenty-nine survey cells were surveyed over 42 days (932 trap nights)"
