Table 1 Summary of method to reconstruct movement paths and infer missed detections from a fine scale camera trap grid

1. Remove duplicates: For cases where two cameras simultaneously photographed the same animal, keep only the record from the camera closest to the animal.

2. Consider detections close in time: Review all records < 5 min from each other if they are the same species, an empty frame, or an unidentifiable animal.

3. Order chronologically: Mark on the map showing the time sequence of photos.

4. Recognize direction of travel: mark on map

5. Reconstruct movement path: Link sequential detections by drawing the shortest Euclidian distance between the detection zone where the target species was photographed, empty frames, and blurry pictures while also considering time of travel.

6. Identify missed detections: If the shortest path between detections crossed a camera that did not record a photograph, record that as a failed detection.
