Overview
The dataset contains 2,278,071 images, collected by the California Department of Fish and Wildlife following a standardized protocol. These data were collected to better understand the potential impacts of land use and climate-related changes on wildlife populations in California. The images were collected from downward-facing, short-focus (factory modified to 40 cm) Reconyx cameras, which were deployed in combination with a drift fence. Image labeling was conducted using the Wildlife Insights platform.
Target species include small mammals, reptiles, and amphibians. In general, images were identified to the taxonomic level possible based on the image alone (species distributions within California were not considered) following these recommendations for mammals and for amphibians and reptiles. The most common categories are blank/misfire (1,320,489 images), mouse species (252,986 images), arvicolinae subfamily (124,342 images), and rodent (112,248 images).
