Data from: Data from camera surveys identifying co-occurrence and occupancy linkages between fishers (Pekania pennanti), rodent prey, mesocarnivores, and larger predators in mixed-conifer forests
These data provide information on the frequency of fisher detections by camera traps, and single-season occupancy and local persistence of fishers in small patches of Sierra Nevada mixed-conifer forest habitats. The data are used to identify basic patterns of co-occurrence with fishers, and to evaluate the relative importance of presence of competing mesocarnivores, rodent prey, and predators for fisher occupancy of small, 1 km^2^ grid cells of forest habitat.
