Individual recaptures are subsequent detections of an individual at the same or new locations. Spatial recaptures of an individual are detections in locations different from the initial and subsequent detections. The number of total detections is the total number of times bears were detected, e.g. in 2004, 119 bears were detected 216 times. Spatial detections count only detections in different locations, e.g. in 2004, 119 bears were detected in 205 unique locations. Mean maximum distance moved (MMDM) is mean distance between detections for each individual identified averaged for all bears. Max distance is the longest distance between 2 detection locations for any individual. Summary does not include 1 detection of a female in 2010 that was 190 km from other detections of that individual that year.
