Country: Indonesia
State: East Java

Coordinate: 5° 45' 0" S, 112° 19' 30" E
Basis of coordinate: stated in text

Climate and habitat
Habitat: tropical/subtropical moist broadleaf forest
Protection: other protected area
Substrate: ground surface
MAT: 27.0
MAP: 2500.0
Habitat comments: "Rainfall is mostly abundant during the north-west monsoon lasting from the end of October until April, and reaches ca. 2.500 mm on the southern coast. Temperature conditions are almost uniform throughout the year, the average of maximum temperature is 32 C and minimum temperature is 22 C... The centre of the island is mountainous with peaks at 400 to 630 m in altitude, and is mainly covered by evergreen tropical forests (4700 ha, ca 23% of the island), including teak (Tectona grandis) plantations... Coastal low hills... are primarily cultivated lands. A mosaic of grassland, shrub, open and closed forest with understory are found in the study area"

Trap spacing: 2.000
Sampling comments: "The BINR-WS area was divided into 20 4 km2 grids... From March to November 2014, 20 units of Bushnell Trophy Cam HD Max digital cameras working on passive infrared motion/heat sensors were installed, one per grid... Because our goal was to monitor Bawean deer... camera traps were deployed in the most promising locations... cameras were set up at 3050 cm above the ground... data were considered independent if photographs were taken more than 0.5 h apart"
trap days for this season are not reported, but table 2 indicates that there were 1220 trap days in each of two sessions
