I am quite sure it is not wild parsnip. We had that on the farm growing up in the '50's and it is too tall, over 5 feet, and no blossoms yet. Assuming it is giant hogweed does Vermont have reporting requirements like those you posted in the New York article you provided?
Hello: Here is a link to the VT Invasives website - https://www.vtinvasives.org/invasive/giant-hogweed I would contact them and let them know what you are dealing with. Thank you.
