Brachypodium sylvaticum, which is very invasive in Oregon, has been found at the Thornewood Open Space Preserve near Woodside in the Santa Cruz Mountains, along the San Francisquito creek at the Alma Caltrain Station, and at Skyline Boulevard and Highway 84.

Samples of the grass have been confirmed to be Brachypodium sylvaticus by the California Department of Food and Agriculture.

If anyone has found this grass elsewhere in the Santa Cruz Mountains, or anywhere in California south of Oregon, please contact Doug Johnson.
