Remote camera stations were set up in Lava Beds National Monument and Modoc National Forest from January to May 2018 to document occurrence of mesocarnivores and other wildlife. Thirty-three cameras were set up at 12 primary sampling units (clusters of one to four cameras) throughout the park. Potentially suitable habitat occurred in small patches in Lava Beds National Monument with cameras were placed in groups of one, two or three. To allow for more primary sampling units of four cameras, some cameras were installed in neighboring portions of Modoc National Forest. Cameras located in Modoc National Forest are considered part of the Lava Beds National Monument survey for the purposes of this study. The dataset contains all species observed within the study time-frame, the date and time of observation and the number of individuals detected as well as identification for individual locations, cameras and images. None of the three target species of conservation concern ((Pacific fisher (Pekania pennanti), Pacific marten (Martes caurina), Sierra Nevada red fox (Vulpes vulpes necator)) were seen, though Gray fox (Urocyon cinereoargenteus) were detected.
