Who are the Invaders in Oregon Estuaries?
Our goal is to summarize the present knowledge of nonindigenous species in Oregon estuaries. The list of exotic species is primarily based on surveys conducted by Jim Carlton (Coos Bay), John Chapman (Columbia River and other estuaries) and the US Environmental Protection Agency (Yaquina Bay). These studies provide evidence that well over 100 invaders have become established in Oregon’s estuaries. It should be noted, however, that this figure is an underestimate because most estuaries, habitats and taxonomic groups have not been systematically sampled.
