Introduced Species in Oregon Estuaries

At present, no coast-wide systematic sampling program exists for monitoring the arrival and spread of exotic invaders. Only Coos Bay has been sampled on a regular basis since 1977 by James T. Carlton and his students. While some habitats and taxonomic groups are well monitored, others such as planktonic, microscopic and deep benthic communities, are not. Consequently, some invaders could be missed. Other Oregon estuaries received very little sampling effort. Species from James Carlton's list for Coos Bay appear in dark green. Those species listed in blue were observed in other estuaries. Introduced speces are indicated by " i " and cryptogenic species of unknown origin, by "c".
