Itadori knotweed (Reynoutria japonica) and climate resiliency

As some hydrological regimes shift towards more frequent and severe storm events in response to climate change, positive feedback loops may develop between existing knotweed populations, sudden riverbank failure, and increased flood-related damage. Mindful action to control these plants is therefore a climate resiliency opportunity. Researcher and manager Brian Colleran and Élisabeth Groeneveld shared their perspectives on managing invasive knotweeds (primarily Itadori knotweed, Reynoutria japonica) in a changing climate and answered questions from the audience.
