Survey Methods: An Overview

Camera-trapping

Infrared motion-sensing cameras are strategically deployed along travel routes used by snow leopards occupying the survey area. The digital images or analog photographs taken of a passing cat are analyzed and the number of individual snow leopards determined from their unique pelage spot patterns or “fingerprinting.”
