We are at a crucial historical moment, in which the International Union for Conservation of Nature Red List has announced a catastrophic decline in global biodiversity. Yet nature is, necessarily, interpreted in museums, through taxidermy dioramas and skeletal mounts; virtual tours and digital databases; image, text and film. The Unnatural History Museum brings together museum professionals and academics across disciplines to platform vital conversations about the museum mediation of the natural world during the sixth mass extinction. Each session will be hosted on Zoom to allow for international participation, and will take the format of short presentations focussed around a specific theme, followed by a synthesised Q&A and roundtable discussion.
