Camera trap observations from the Likely Tables, Modoc County, California

Records of mammals observed at camera traps set up along fencelines on the Likely Tables in Modoc County, California. Each entry corresponds to the first photo in a series with the species identifiable in the photo. Subsequent photos taken without a gap longer than 5 minutes were used to determine whether animals moved parallel to the fence, approached the fence (i.e., were observed closer to the fence and on the same side in successive photos), crossed the fence, or moved away from the fence (i.e., were observed further away from the fence but on the same side in successive photos). In photo series with >1 individuals of the same species, no distinction is made between the same individual exhibiting multiple behaviors or different individuals each exhibiting different behaviors. Behavior data is a binary response indicating that at least one individual exhibited the behavior at least once during the photo series.
