Federal wildlife officials and volunteers are scheduled this to begin removing sea plants and shellfish that still cling to the side of the Japanese dock that washed ashore Sunday night at Agate Beach. Its origin have been traced back to a fishing village on the east coast of the Japanese island of Honshu, about 70 miles north of Tokyo. There are indications on the dock that it was violently ripped from its moorage giving weight to the assumption it was involved in the Japanese earthquake of March 11, 2011 and the ensuing tsunami.
U.S. Fish and Wildlife scientists say some of what covers the dock are native species but some are from Japan. As a precaution against the invasive species getting a “shell or plant hold” on the Oregon Coast, scientists and volunteers are scheduled to begin scraping the dock clean of these biological hitch-hikers. Among them are mussels, barnacles and marine algaes. Scientists say one invasive marine algae in particular called “wakame” is especially troublesome and they’re going over the dock very meticulously to try to make sure they get it all.

There has yet to be an announcement made about how the dock is to be removed from the beach.
