Non-Native and Invasive Species

Non-native and invasive species can alter and degrade habitats, increase threats to native species, and in some cases impact local economies or cause extensive problems for marine coastal systems of Oregon. Non-native species can be transported locally, regionally, or around the world and introduced to Oregon’s nearshore systems by way of several mechanisms such as, hitch-hiking in ballast water or in ocean currents. Once a species has been introduced it can affect food sources, alter habitats, expose native communities to diseases or toxins, or act as parasites of juvenile and adult members of coastal fisheries species. For many introduced species, the severity of the potential ecological threat is not yet known. Many of these species could be deemed invasive in the future, but further efforts to assess impacts are needed. These efforts are a priority for conservation of natural systems because invasions become more complicated to address over time and management measures that respond to the first arriving individuals are most effective.

Efforts have begun to assess available data regarding existing or potential future threats to Oregon’s nearshore and estuarine communities. The Oregon Department of Fish and Wildlife’s Marine Resources Program reviewed available online data and consulted with experts at Oregon State University, the Environmental Protection Agency Western Ecology Division, United States Geological Survey Western Fisheries Research Center, and Williams College in 2012 and updated this information in 2015. Based on information gleaned from these sources, a list of non-native species known to occur in the nearshore waters of Oregon and neighboring states was developed. For each species, habitat information was collected and species were identified as being primarily associated with nearshore marine and/or estuarine systems.

a     Nearshore = species is primarily associated with the nearshore marine habitat, between the high tide line and the territorial sea boundary.
b     Estuarine = species is primarily associated with estuarine habitat.
c   1: OR Invasive = non-native species is present in Oregon and is considered invasive for posing a threat to native species.
d   2: OR Non-native = non-native species is present in Oregon and the threat to native species is unknown
e   3: WA or CA Invasive = species is present in states adjacent to Oregon and is considered invasive.
Species listed here are associated with nearshore and estuarine west coast habitats, as determined by analysis of data and expert review provided by James T. Carlton, Williams College; John Chapman, Oregon State University; Debbie Reusser, U.S. Geological Survey – Western Fisheries Research Center; Henry Lee, U.S. Environmental Protection Agency – Western Ecology Division; and Gayle Hansen, Oregon State University.
