Basic information
Sample name: Bawean Island (wet season)

Reference: D. A. Rahman, G. Gonzalez, and S. Aulagnier. 2016. Benefit of camera trapping for surveying the critically endangered Bawean deer Axis kuhlii (Temminck, 1836). Tropical Zoology 29(4):155-172 [ER 3019]
Geography
Country: Indonesia

State: East Java


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

Geography comments: most sampling was "in the Bawean Island Nature Reserve and Wildlife Sanctuary (BINR-WS), and in Tanjung Cina, a peninsula (ca. 950 m × 300 m) where there is no resident human population" and specifically "surveys focused on the wildlife sanctuary (ca. 3832 ha) and nature reserve (ca. 725 ha), and additionally on Tanjung Cina"

Environment
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"

Methods
Life forms: carnivores,primates,rodents,ungulates,lizards

Focal species: Axis kuhlii

Sampling methods: quadrat,automatic cameras

Sample size: 817 captures or sightings

Years: 2014

Seasons: wet or monsoon

Nets or traps: 20

Net or trap nights: 2440

Camera type: digital

Cameras paired: no

Trap spacing: 2

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 30–50 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
