Topic: invasive species

David Lodge discusses environmental DNA as a tool for detecting invasive species and the challenges of translating ecological evidence into policy. The conversation follows invasive-carp detection in river water, scrutiny in legal proceedings, long-term crayfish observations, and the respective roles of researchers and decision-makers.

Preventing biological invasions requires coordinated action before and after organisms arrive. This seminar examines the regulatory frameworks, biosecurity practices, public education and collective action used to reduce introductions and manage invasive species.
