Abstract

The Asian kelp Undaria pinnatifida was discovered in southern California in the spring of 2000, and by the summer of 2001 had been collected at several California sites from Los Angeles to Long Beach Harbors and Catalina Island as far north as Monterey Harbor. From its native range in the northwestern Pacific, Undaria has now been introduced to the northeastern and southwestern Atlantic and the southwestern and northeastern Pacific, through a combination of intentional transport for cultivation, accidental transport with oysters, as fouling on vessel hulls, and possibly other means. In the northeastern Pacific, water temperatures are suitable for its establishment from at least Baja California to British Columbia, where it is likely to grow well in sheltered and partially sheltered waters.
