Crayfish Invasion

OPB | Feb. 17, 2011 12:30 p.m.

Invasive crayfish from the east have been spotted for the 1st time west of the Rockies, in a river in Eastern Oregon and a stream in Corvallis. They were shipped to elementary schools for biology classes and then released where they don’t belong by well meaning children or their teachers. The shipments of live classroom specimens violates state wildlife laws but state authorities have chosen not to aggressively enforce the ban.
