Notice of Availability of a Supplemental Environmental Assessment for Release of Aphalara itadori From Murakami, Japan for the Biological Control of Japanese, Giant, and Bohemian Knotweeds in the Contiguous United States

Résumé

We are advising the public that the Animal and Plant Health Inspection Service has prepared a supplemental environmental assessment (EA) relative to a 2020 EA for the release of Aphalara itadori for the biological control of Japanese, Giant, and Bohemian knotweeds (Fallopia japonica, F. sachalinensis, and F. x bohemica), significant invasive weeds, within the contiguous United States. This supplement analyzes the potential impacts of the release of A. itadori from Murakami, Japan, that may be more effective than the present Hokkaido and Kyushu lines of A. itadori in reducing infestations of knotweeds, particularly hybrid knotweed, which is the most abundant type of knotweed in the United States. We are making the supplemental EA available to the public for review and comment.
