Endangered Plant Survey, Antioch Dunes (Day 2)

Come help count Contra Costa wallflowers, an endangered plant, at the Antioch Dunes National Wildlife Refuge Sardis Unit with US Fish & Wildlife Service staff.

The Antioch dunes is a unique site that hosts an endangered butterfly as well.

See flyer for more details.


From 680 heading north (near Walnut Creek/Concord), take Hwy. 242 E, which will lead you onto Hwy 4 E towards Pittsburg/Antioch. Continue on Hwy 4 to Antioch.

From 680 heading south (from Benicia/Martinez), take Hwy 4 E towards Pittsburg/Antioch.

At Antioch, take A Street/Lone Tree Way exit and go L under freeway. Proceed about 1 mile on A Street and then go R onto Wilbur Avenue. Proceed on Wilbur about 1 mile, cross over a concrete bridge and look for two large PG&E towers on L. The entrance gate will be on the L between the two towers.

    This is a great place that is usually inaccessible to the public. I'll probably have to work on that weekday, but enjoy the Contra Costa wallflowers for me.
