Comments

Hi stemweek1A,

Thanks for getting out to look for Japanese knotweed. It does look like your coordinates are off. Your trip says you were at USM but the coordinates put you on Mackworth Island. Please leave a comment below with the correct coordinates so we can update your observation.

Sorry about that!

Here are the correct coordinates:

43.662379, -70.279934

Thanks for the speedy reply. You are back on track.

Thanks,
The VS Team

I'm sorry to say this, but you need to look again in your pictures. I think I see some knotweed in the upper left corner of your Observation Site Information picture...

I wish knotweed weren't so well established in Maine!
