Sunday (Saturday) in the Park

A bit late, I know. See last week's edition for more leads.

• They pulled garlic mustard (Alliaria petiolata) this weekend near Wilmot, OH.
• Volunteers in Lincoln, MA (scroll down page) learned to identify and get rid of garlic mustard and black swallow-wort (Cynanchum louiseae).
• If you were in Belfast, Ireland this weekend, you could have been clearing Japanese knotweed (Fallopia japonica) from a nature reserve.
