Chris Sanderson is an Ecologist and PhD Candidate at the University of Queensland. He joined us to discuss butterflies, birds, threatened species, and IT, over Mexican Butterfly cocktails. Chris is studying how threatened species listings and legislation processes differ across the country, the impacts of data deficiency, and ways to improve these processes. He also works as a project officer on “Butterflies Australia”, a new citizen-science app for recording butterfly sightings and data, including a free digital field guide, and plenty of interesting features in development to explore butterfly data in map form.
