Common names: slender false-brome; false-brome

Brachypodium sylvaticum (slender false-brome) is a perennial bunchgrass (family Poaceae) whose known distribution in California is currently limited to portions of San Mateo and Santa Clara Counties. Perennial false-brome was introduced to Oregon in 1930, where it spread rapidly in forests and upland prairies, especially along roadsides and trails. It forms a dense cover that may suppress forest regeneration, degrade wildlife habitat, and increase fire risks. In California it has invaded redwood groves, and there is concern that it could damage this limited habitat type.
