Geography
Country: Indonesia

State: Jambi



Coordinate: 2° 1' S, 103° 20' E
Coordinate basis: based on political unit

Geography comments: "in the regency of Batang Hari, province of Jambi"
Drescher et al. () indicate that the sites are spread over an area at least 50 km across covering much the regency, all of which is southwest of Jambi City
coordinate is based on Batang Hari

Environment
Habitat: tropical/subtropical moist broadleaf forest

Altered habitat: plantation

Protection: unprotected

Substrate: ground surface

Disturbance: selective logging

Habitat comments: "upland and riparian oil palm plantations... between 9 and 20 years old... all plantations were monoculture smallholdings using less intensive crop management (weeding, fertilizing, harvesting) than company estates"

Methods
Life forms: lizards,snakes,frogs

Sampling methods: no design,pitfall traps,auditory,hand capture

Sample size: 552 individuals

Years: 2017

Sampling comments: "We collected data from April 4, 2017 until July 9, 2017 in 24 core plots... For each habitat, there were four square, replicate plots of 50 x 50 m, situated in different plantations... We coupled visual and aural surveys with pitfall traps... each plot was visited six times for 1 h by two herpetologists (AP and HJ), resulting in 12 person-hours of visual-aural surveys per plot, and 288 person-hours overall... We also set up four pitfall traps per plot, one in the centre of each of the four sections... they were active for approximately 36 h... we also mounted four pitfall traps in each plot, for a total of 192 trap installations"
animals "were temporarily captured" and detected by identifying calls
forest plots were sampled in June and July
