This week, we’re rebroadcasting an episode from the Resources Radio archive while the team is on a break through the rest of December. We’ll be back with new episodes in the new year; in the meantime, enjoy this throwback and poke around the archive at Resources.org for more topics you might be interested in. In this week’s episode rerun, host Kristin Hayes talks with Rebecca Epanchin-Niell, a senior fellow at Resources for the Future (RFF) who coauthored a journal article with RFF scholars Alexandra Thompson and Tyler Treakle about the role of the public in detecting invasive species. Pointing to a recent incident in which a member of the public spotted an Asian giant hornet in Washington State, Epanchin-Niell describes how more than a quarter of detections of invasive species—and possibly more—stem from these citizen scientists. Recognizing the essential role of the public, policymakers can make it easier to alert authorities about the presence of unusual species.
