Remote camera stations were set up in Lassen Volcanic National Park from August to October 2017 and June to September 2018 to document occurrence of mesocarnivores and other wildlife. 126 cameras were set up at 32 primary sampling units (clusters of two to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. 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. Of the three target species of conservation concern (Pacific fisher (Pekania pennanti), Pacific marten (Martes...
