Geography
Country: Malaysia
State: Sarawak

Coordinate: 2° 25' N, 112° 50' E
Basis of coordinate: estimated from map
Geography comments: "The Anap Sustainable Development Unit (ASDU) is located in the Tatau district in Bintulu Division, central Sarawak"
"Elevations ranged from 94 to 366 m"
Climate and habitat
Habitat: tropical/subtropical moist broadleaf forest
Altered habitat: disturbed forest
Protection: unprotected
Substrate: ground surface
Disturbance: selective logging
Habitat comments: "The ASDU includes the Anap-Muput Forest Management Unit (AMFMU), which covers an area of 835 km2, and an area of Licence for Planted Forests (LPF/0039), which covers 232 km2"
"Logging operations in the AMFMU began in 1977 ... with a reduced-impact logging method applied since 2008"
Most study areas have been harvested at least once or twice, "ranging from 0 to 6 years since the last harvest"
"At the time of the survey, vegetation in plot C01 (LPF/0039) was a natural forest, but had been harvested more than three times"
"The vegetation type in all the plots was lowland mixed dipterocarp forest, except for one which contained kerangas forest"
Methods
Life forms: carnivores, primates, rodents, ungulates, other large mammals, other small mammals, birds
Sampling methods: no design, automatic cameras
Sample size: 6924
Years: 2011 - 2013
Nets or traps: 64
Net or trap nights: 41467
Camera type: digital
Cameras paired: no
Sampling comments: "We undertook a camera trapping survey from May 2011 to June 2013"
"Eight study plots, each with a radius of 500 m, were established in the ASDU"
"One plot was inside the LPF/0039, whereas the other seven plots were inside the AMFMU"
"In each plot, we randomly generated eight setting points for camera traps" (64 camera traps in total)
"The cameras used were Bushnell Trophy Cams, which were mounted on a tree 50100 cm above the ground"
"The cameras were set to record in video mode for 10 seconds upon triggering, and were checked every 35 months"
