Four introduced, invasive species of Spartina (cordgrass) have been present in estuarine areas of the U.S. west coast for over a century. These Spartina species are ecological engineers- they cause severe...

Since the mid-1900’s, invasive aquatic weeds have been a significant problem in many of the lakes of the Clatsop Plains on the northern Oregon Coast. Weeds interfere with beneficial uses, such as boating,...
