We had another good group, a dozen volunteers or more, including first-time Palos volunteers David and Maribel. The day was focused primarily on butterweed which was growing in several large clusters adjacent to the woodland. This stuff is persistent and spreads quickly; what remains to be seen if whether our pulling prevents further spread.
We're in full summer mode now, going after weeds whether by pulling or dead-heading. There's quite an assortment out there - I saw thistles, teasel, and wild parsnip on a recent prairie walk. That's ok, will keep me out of the gin mills and their modern equivalent, the weed shops.
