Project CRESCO Citizen Rescuers for Collections aims to engage a broad audience in the valorization of the biological collections of the Institute of Natural Sciences and the AfricaMuseum through virtual projects and physical onsite Citizen Science digitization and collection management actions. Citizens help preserve biology collections by contributing to research, from home or inside the museum. They do that by transcribing and annotating labels of insects, by preparing wood samples or by cleaning and photographing bird specimens.
