Geography
Country: Bangladesh


Coordinate: 24° 15' N, 91° 55' E
Coordinate basis: estimated from map

Geography comments: Rajkandi is a ∼62 km2 Forest Reserve located in northeastern Bangladesh
"The topography is hilly with elevations ranging from 50 to 300 m"

Environment
Habitat: tropical/subtropical dry broadleaf forest

Altered habitat: fragment

Protection: unprotected

Substrate: ground surface

WMT: 32.0

CMT: 9.0

MAP: 3334.0

Habitat comments: "Northeastern Bangladesh ... once harboured a diverse array of forest types, from tropical evergreen, to mixed and/or semi-evergreen forest"
"The landscape is now heavily fragmented, and the remaining forest is mostly confined to ten patches varying in size from 10 to 100 km2"
"Remaining forests are mostly of three types: semi-evergreen hill forest, shrubs, or mixed bamboo forest"
"Annual temperature ranges from 32 °C (August–October) to 9 °C (January), and nearly 80% of the annual average rainfall (3334 mm) occurs between May and October"
"Although designated a "Reserve Forest", Rajkandi is not officially protected"

Methods
Life forms: carnivores,primates,rodents,ungulates

Sampling methods: no design,automatic cameras

Sample size: 532 captures or sightings

Years: 2014, 2015

Days: 95

Seasons: dry

Nets or traps: 12

Net or trap nights: 399

Camera type: digital

Cameras paired: no

Trap spacing: 1.1

Sampling comments: "At each station, we deployed a single camera trap (Bushnell Trophy Cam HD™)"
"We set trap stations approximately 1.1 km apart opportunistically throughout the forest fragment"
"We mounted each camera to a tree, approximately 25-30 cm above the ground, with metal chain, and inside a theft-proof box made of steel"
"To maximize the capture probability of felids, we used scent-based lures, randomly alternating between either Calvin Klein Obsession for Men, or chicken body parts"
"In some locations we also used an additional visual attractant (a chicken feather)"
"Each camera was active for 24 h per day and programmed to take two photos per trigger event, with a 15s delay before a subsequent trigger event could occur"
