Summary:Eradicating or reducing populations of alien invasive species is exceptionally difficult once they have become established. However, successful instances of eradication and reduction are becoming more common with ongoing refinement and advancement in management strategies. In Hakone, Kanagawa Prefecture, Japan, attempts to eradicate the alien invasive plant Rudbeckia laciniata L. have been in progress over the past decade with a recent dramatic reduction in population density. Here, we report the processes used over this decade-long eradication campaign and discuss the key factors promoting success based on monitoring records. We believe that the lessons learned in our region will be useful for similar invasive species management in other regions.
