A thorough understanding of how camera traps function is essential for ensuring correct set-up and quality of data. We illustrate the challenges through a case study of camera trapping an otter Lutra lutra resting and breeding place. Appropriate survey design, such as using multiple cameras, decreasing the distance between cameraand otter holt entrance, and camera trapping for sufficient duration, is likely to reduce the propensity for false negatives and increase our ability to correctly identify and protect mammal resting places. |
