Coast Cleanup – Invasive Plant Removal in McNabney Marsh

Saturday, September 16

9:30 am – 11:30 am

Please join us on Coast Cleanup Day – September 16 – to remove invasive stinkwort (Dittrichia graveolens) from the edges of McNabney Marsh. Stinkwort was first reported in California (Santa Clara County) in 1984. It has now spread to 36 counties including Contra Costa. Stinkwort is not palatable, can be poisonous to livestock, and can cause contact dermatitis in people. It is found primarily along roadsides and other disturbed sites. Unlike many annuals, stinkwort flowers and produces seeds from September to December – so this is a good time to remove it. If you are up for a little work, you can help us make a big difference in the spread of this invasive plant. Reservations and signed liability forms are REQUIRED. We will provide: latex gloves, plastic bags, water, and a pizza lunch at the end of the day. Participants bring: work gloves, a hat, and sunscreen and wear long pants and closed-toed shoes. A mat or knee pads are also recommended. For more info and to RSVP, contact Heidi Petty at:
