Traps were placed ∼1 km apart across the study site, and their spatial coordinates
were recorded using a global positioning system receiver. Cameras were set
to operate 24 h/d with no more than mechanical minimum delay between
sequential photographs. For each picture, we recorded entity (i.e., tiger, prey
species, or human presence type), location (based on trap identification),
date, and time. We summed the number of detections for each entity for
each camera trap. Detections were defined as
