An invasive species is both non-native to the ecosystem in which it is found and capable of causing environmental, economic, or human harm because of its ability to spread rapidly and compete with native species. Also, like wildfires, invasive infestations are best controlled when small in size. Nutria eat tall grasses and rushes. These actions, or management approaches, are not a cure-all but can give states, counties, private landowners, and public land managers a framework for prioritizing efforts to guard Strategy Species, Strategy Habitats, and working landscapes against invading organisms.

The ODFW seeks to prevent the uncontrolled spread of these species and will evaluate situations on a case-by-case basis.

Landowners may not report invasive species on their propertydue toconcerns that disclosure of infestations may lower property values or that they may be held responsible for treatment costs.
