Research overview: Snapshot Safari and Snapshot USA continental networks

Snapshot Safari and Snapshot USA are large collaborative camera-trap networks that aggregate standardized surveys across many sites, in African reserves and across the United States respectively, to study mammal communities at continental scale. This overview surveys how these programs coordinate numerous research teams under shared protocols, pool images for citizen-science classification, and produce datasets enabling cross-site comparisons of diversity, abundance, and responses to land use and environmental gradients. It discusses the value of synchronized, standardized deployments for detecting broad patterns, the role of crowdsourced and machine-learning image processing, and the open data that fuels both ecology and computer-vision research. The overview highlights how distributed, networked camera trapping transforms isolated local studies into powerful continental observatories of wildlife, advancing understanding of how mammal communities, including felids, vary and change across vast regions.
