I have found what I think is Acacia verticillata at Tomales Bay State Park in Marin County.

It is not listed as invasive by Cal-IPC but there are quite a number of plants along the trail to Shell Beach, in the parking lot, and along the road leading up to the parking area. Is this something we should worry about?

 

It looks like it was noted by Marin CNPS in 2001 and also found in the resource inventory for Angel Island in 1980.
