Environment
Habitat: tropical/subtropical moist broadleaf forest
Altered habitat: plantation
Protection: unprotected
Substrate: ground surface
Habitat comments: "first cleared for planting in 1993" with "stands of fast-growing Acacia mangium (70% of plantation land cover) and Eucalyptus spp. (20% of plantation land cover) of varying age, interspersed with patches of secondary forest (10% of plantation land cover)"
Methods
Life forms: carnivores, primates, rodents, ungulates, other small mammals
Sites: 8
Sampling methods: quadrat, baited, automatic cameras
Sample size: 417 captures or sightings
Years: 2012, 2013
Net or trap nights: 2065
Camera type: digital
Trap spacing: 0.5
Basal area status: not applicable
Sampling comments: "we placed arrays of camera traps and nest transects at eight study sites distributed across the three different habitat types (acacia, eucalyptus, and secondary forest)... Each study site (N = 8) contained at least one survey location, each of which consisted of a camera trap array... We collected camera trap and nest data September 2012-March 2013. Each camera trap array consisted of 6-11 Bushnell Trophy Cams placed in a grid with cameras 500 m apart... We baited each camera with one or two durian fruits... we considered photos to be independent captures of a species if they were taken at different camera traps, or on separate days at the same camera trap"
