We often hear about the damage caused by invasive insects and plants. Today we turn our attention to marine invasives. We’ll learn how citizen scientists of the Marine Invader Monitoring and Information Collaborative (MIMIC) are working with researchers from the Wells Reserve to track these species along Maine's coast.

Jonathan was born in Monsey, New York. A field trip to Washington, DC when he was in 7th grade started him on his circuitous path to a career in public radio. The trip inspired a love of politics and led to his desire to one day call DC home. After graduating from Grinnell College, he worked on a couple of campaigns in Iowa (presidential and congressional) and moved to Washington, DC.
