Pulling broom in Tilden

You're never too young, or too old, to remove invasive, fire-prone French broom! Our July 22 work party removed re-sprouts near Tilden Regional Park's historic carousel, while our Weed Warriors did heroic work in the El Cerrito Hillside Natural Area.

New and Seasonal:

Shorebirds are back. Late summer wildflowers are blooming along the Bay. And it's a great time to help the environment by gathering, and relishing, edible weeds!

Salsola soda, or agrettiAlong the Bay, salt-marsh plants are in bloom. Displays rival many mountain meadows! Click here for our slide show.  Fall migrants on shorebirds' long journeys, some from the Arctic to South America, are already on the tide flats. Hundreds of Western sandpipers feasted at the mouth of Strawberry Creek during our July 15 work party with Integrated Project Management. Click here for our video on how these birds need mudflats like those at the mouths of Strawberry, Schoolhouse, and Codornices Creeks -- all places where F5C volunteers are active.

Discover great wild foods from invasives in late summer! Left: Salsola soda -- Agretti to the Italians -- is delicious fresh or lightly steamed. Gather it along the Bay and help keep it from crowding out natives! Fennel pollen makes a delicious spice, and Himalayan blackberries can be beat for jam. Our handout, Edible and Useful Wild Plants, has broad info -- spare the natives, and gather the weeds to help the environment!
