Brachypodium sylvaticum Alert
Brachypodium sylvaticum (false-brome), a grass 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. This grass is capable of completely dominating the forest understory, including redwood forest understory, to the exclusion of all other plants. The dense layer of thatch that false-brome creates may increase the risk of wildfire.
Samples of the grass have been confirmed as Brachypodium sylvaticum by the California Department of Food and Agriculture.
If anyone has found this species elsewhere in the Santa Cruz Mountains or anywhere else in California, please contact Cal-IPC.
