Submitter does not have a specimen
EDRR Status: Local expert notified
widely scattered plants covering a few acres.
I pulled a number of them during several visits this summer but I did not get them all.
It seems like a good time to nip the population in the bug before it spreads.
(there is also some knotweed on this island).
