Slender false brome (Brachypodium sylvaticum) is a new and potentially destructive invasive species present in the Woodside area, the only known location of this weed in California. In Oregon, slender false brome has spread to over 10,000 acres and is a major environmental problem. In California, slender false brome has been given the highest rating as a Class A Noxious Weed.
A perennial bunch grass originally from Europe, Asia, and North Africa, slender false brome is capable of achieving over 90% ground cover, inhibiting the growth of tree seedlings, and replacing native vegetation.
Midpen is managing slender false brome in its Thornewood Open Space Preserve; however, large stands exist on surrounding private properties in the Woodside area, and plants have been found as far away as La Honda. Working together with the local community, the District hopes that slender false brome can be eradicated in the Woodside area before it spreads throughout the state, becomes unmanageable, and alters the area’s redwood forests and natural environment.
Treating Slender False Brome on Private Properties
The District helps private property owners treat slender false brome on their property. Working with community partners, Midpen will assist the community in understanding, identifying, and safely removing the weed from their property.
In July 2011, the Midpeninsula Regional Open Space District presented a free public workshop led by Mark Heath, Certified Pest Control Advisor. Several contractors attended the workshop, which covered program details, reasons for slender false brome removal, weed identification, safe and effective removal options, and a question and answer session.
