Please note that the “last Saturday of the month” invasives work day is cancelled for this month. However, if you have worked with us in the past and can identify oriental bittersweet seedlings, and you would like to go ahead on out to the Riverstone Preserve and work, please feel free to do that. We appreciate your help! We will host another invasives work day on Saturday, August 27 from 9 AM to 11. Please put that date in your calendars. Thank you!
