Knee height is often right: evaluating device height effects on camera trapping rate
Remote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 531-544, August 2026.Camera trap deployment height can introduce systematic biases in detection trapping rates across species of different body sizes. Combining 172 paired sampling points in five experiments across Europe, North America and Africa, our results show that low cameras significantly increase detections of small‐ and medium‐sized species, whereas high cameras ...
