The survey found widespread distribution of otters in the study area. Otters were detected across a range of waterbody types and habitats, from small burns to wider rivers, Loch an Eilein and Loch Morlich, and at elevations up to 628 metres. Camera trapping proved to be an effective tool for monitoring otter presence and added an important temporal dimension to activity patterns. 10% of otter detections occurred during daylight, 90% at night. Eleven of 15 camera sites provided photographic evidence of otter occupancy, including some video footage. A total of eight identifiable mammal species were recorded by the traps. The primary survey methodology used transect surveys; the results of these are not included in the present dataset. Bird species detected by the camera traps are also not included.
