Reasons: Occurs, as native, in California, near coast, Ventura to Del Norte counties and northward. This species was planted in Oregon as a 'sand binder' (Peck 1961) and it has naturalized north into Washington and British Columbia. This species in California grades into L. rivularis in the North Coastal range (Hickman 1993). Further, this species is considered 'invasive' and is hybridizing with L. rivularis in British Columbia (COSEWIC 2002).
