Geography
Country: South Africa
Coordinate: -33.646252° S, 21.650999° E
Coordinate basis: stated in text
Geography comments: "Our study site was Groenefontein Nature Reserve... and an adjoining, privately-owned property... Both properties form part of the Rooiberg Conservancy"
Environment
Habitat: desert/xeric shrubland
Protection: nature reserve
Substrate: ground surface
MAT: 17.7
MAP: 244.0
Habitat comments: "We sampled biodiversity with camera traps in three vegetation types: fynbos, subtropical thicket, and riverine vegetation"; the latter forms "dense clumps of bush separated by open areas"
climate data are for Oudtshoorn and are from Schmiedel and Jürgens (2004, Plant Ecology)

Methods
Life forms: carnivores,primates,rodents,ungulates,other large mammals,other small mammals
Sampling methods: line transect,automatic cameras
Sample size: 232 captures or sightings
Years: 2012
Nets or traps: 15
Net or trap nights: 1148
Camera type: digital
Cameras paired: no
Trap spacing: 0.025
Sampling comments: the reserve is 5200 ha and adjoining property 1100 ha; it is not clear whether the cameras cover the entire area
"three 100 m transects a minimum of 1 km apart... Camera traps were placed at 25 m intervals with the first camera on the road and the remaining four in a perpendicular straight line leading away from the edge of the road... Sampling was done with Cuddeback Capture cameras... All transects were run simultaneously for a period of approximately 90 days during the period from late August to early December 2012... Camera failure was low in fynbos vegetation (two cameras failed, 26 trap nights lost)"
