The monarch butterfly is popular and currently in the news a lot. You might think that we know all there is to know about it, but there are many mysteries remaining, particularly about their migration and how they use their habitat. This may be more so for the western population that overwinters in California. Radio tracking has long been used for studying the movement and habitat use of bigger animals. Advances in this technology mean it is emerging as a tool that can provide scientists with some answers about tiny animals too.

To explore how radio tracking — also called radio telemetry — can be used with monarchs, we are joined by Ashley Fisher. Ashley is an endangered species conservation biologist and a monarch overwintering specialist with the Xerces Society. Based near the overwintering sites in California, Ashley manages Xerces’ overwintering habitat database and helps facilitate research projects, working with Xerces partnering organizations and universities. She also works with local land managers in communities along the central coast of California to provide guidance on the management and restoration of overwintering sites.
