The kelp Undaria pinnatifida (Harvey) Suringar (Laminariales, Phaeophyceae), a native of Japan, northern China, and Korea, is now established at multiple locations throughout the world, including the west coast of the United States and Mexico. In 2000, U. pinnatifida was first reported in the United States from Los Angeles Harbor, California. Within a year, it had also been found 500 km to the north, in Monterey Harbor, California. In 2002, this alga was reported from Ensenada, Mexico to Monterey, California, and no subsequent spread has been reported since this time. In May 2009, we discovered U. pinnatifida to the north, at two marinas in San Francisco Bay and the outer coastal harbor at Pillar Point, San Mateo County. All observed individuals were removed and measured. Based on size and reproductive status, it appears that multiple cohorts were present. Transfer on the hulls of recreational boats is suggested as the source of this recent range expansion in California. Given the large flux of both recreational and commercial boat traffic in San Francisco Bay, this may become an important source for further spread both along the coast and to other biogeographic regions.
