The dock is believed to be debris from the March 2011 tsunami in Japan, though the Japanese government has yet to confirm this.
Ecology Department spokesman Curt Hart said a six-member team from Olympic National Park and the state Department of Fish and Wildlife removed protective bumpers and decontaminated the outer dock surface with a diluted bleach solution on Friday.
The team put the organic material in an upland area outside the surf zone where the marine species won't survive.
Hart said initial lab results identified as many as 50 plant and animal species on the dock that are native to Japan, including algae, seaweed, mussels and barnacles.
State and federal officials will start planning next week how to remove the dock from the beach.
A Coast Guard helicopter crew spotted the dock Dec. 18 on the remote beach, part of Olympic National Park.
