Habitat: tropical/subtropical moist broadleaf forest

Altered habitat: secondary forest

Protection: unprotected

Substrate: ground surface

Disturbance: agriculture,grazing

MAT: 26.0

MAP: 3250.0

Habitat comments: "The climate is hot, humid, and rainy, with the average temperature and precipitation ranging from 24 to 28°C and 2,500–4,000 mm, respectively"
"The landscape is composed of fragments of high and medium subperennifolia tropical forest, secondary vegetation, annual crops, and forest plantations and pastures, with the latter being the dominant matrix"

Life forms: carnivores,rodents,ungulates,other large mammals,other small mammals

Sampling methods: no design,automatic cameras

Sample size: 1266 captures or sightings

Years: 2017, 2018

Days: 178

Nets or traps: 36

Net or trap nights: 2136

Camera type: digital

Cameras paired: no

Sampling comments: "We identified and selected nine secondary forest fragments and nine mature oil palm plantations (>10 years old) for the mammal surveys"
"Within each of these sites we placed four camera traps (Browning Strike Force™ HD PRO, United States) ≥200 m from one another at a height of 0.5 m from the ground and secured with a cable lock"
"All cameras were configured to medium sensitivity and one-second intervals between consecutive photographs (four per trigger)"
"All sites were not sampled simultaneously, but rather surveys were organized sequentially in different sessions to cover the three main seasons of the region: cold fronts, dry, and wet"
"The first sampling session took place from 15 December 2017 to 15 February 2018; the second from 19 April to 3 July 2018, and the third from 19 October to 17 December 2018"
"During each sampling session 24 cameras were active within six different sites: three oil palm plantations and three forest fragments"
Consequently, there were a total of 36 camera traps across the nine secondary forest fragments (4 traps x 3 sites x 3 sessions), with three different secondary forest sites sampled in each session (nine sites total)
