01 The starting point
A camera trap records an encounter with its field of view. It does not count every tiger in the surrounding landscape. The same animal may appear repeatedly, while another may never pass a working camera. A large folder of photographs is an exciting starting point, but it is not a population total.
02 Look a little closer
Before comparing reports, ask where cameras operated, for how long and with what interruptions. Changes in coverage or working time can change the number of photographs without a matching change in animals. Clear reporting should separate images, independently identified individuals and any wider population estimate produced from the study.
03 Keep the context
Individual recognition helps researchers connect repeat encounters. Estimation then requires an appropriate method and an account of uncertainty, including the possibility of animals missed by the survey. Readers do not need to reproduce the analysis, but they should be able to find its geographic scope, observation period and stated limitations.
04 A useful question
A blank record deserves the same care as a dramatic image. No detection at one camera does not establish absence from an entire forest. Conversely, one sighting does not establish a breeding population. Good reporting preserves those distinctions and avoids declaring success or disappearance from evidence that answers a much narrower question.
