NEWPORT, Ore. — After a large dock from the Japanese tsunami washed ashore last June on a Newport beach, volunteers scraped off 2 tons of seaweed and creatures that had hitched a ride across the Pacific.

They were buried above the high-water line, and the dock was scorched with torches to sterilize it.

Officials are concerned about non-native species invading Oregon waters.

A manager of marine resources for Oregon Department of Fish and Wildlife, Caren Braby, says the dock carried four species — a seaweed, a sea star, a mussel and a shore crab — that are native to Japan and have established themselves as invasive species elsewhere.

She said officials won’t know for a couple years whether any of them escaped to get a foothold in Oregon.
