Indicator Status of Plants Found in Oregon Wetlands

This is based entirely on the 1988 and 1993 lists for USFWS Region 9. Names of many species have since changed, and some species have been split or lumped with others that have a different indicator status or no indicator status. Click on red Comments tab in cells/species to see explanations of changes. If changes generally reflect a name-for-name change, then the indicator status is listed with the new name, but the original name that was the basis for the indicator status assignment is shown as a comment in the cell. In cases where the name change was more complex, the indicator status is preceded with an asterisk (*), or is stated as NOL, or may be left blank.
