In this episode, Chris heads out to Black Earth Creek to meet Tim Campbell, an aquatic invasive species expert who works for the University of Wisconsin Sea Grant. In between dodging traffic and wildlife, they share a candid conversation on invasive species, on specific organisms affecting Wisconsin and on how to think about the proliferation of unwanted flora and fauna in general. Tim explains the challenges of conducting effective public outreach on such invasives, as well as the role that watersheds play in the spread of undesirable species.
