California Rapid Assessment Method for Wetlands v. 5.0.2 – Appendix V
APPENDIX V: INVASIVE PLANT SPECIES LIST
1
In general, code names consist of the first two letters of the genus and the first two letters of the species. For species in which this
formula produces duplicate code names within the list, the final letter in the code is changed for one of the two species. In all such
cases, the resulting code names of both species are presented in bold as a “flag” to warn the observer about the potential for an error of
duplication. The invasive status is based upon species with a rating of high, moderate, and limited in the Cal-IPC Invasive Plant
Inventory (Cal-IPC 2006). Indicator status is from the U.S. Fish and Wildlife Service's National List of Plant Species That Occur in
Wetlands: California (Region 0), May 1988. FAC=Facultative, FACU=Facultative Upland, FACW=Facultative Wetland, NI=No
Indicator, OBL=Obligate Wetland, UPL=Obligate Upland, na=Indicator status not available. A positive (+) or negative (-) sign is used
with the Facultative Indicator categories to more specifically define the regional frequency of occurrence in wetlands. The positive sign
indicates a frequency toward the higher end of the category (more frequently found in wetlands), and a negative sign indicates a
frequency toward the lower end of the category (less frequently found in wetlands). An asterisk (*) following a regional Indicator
identifies tentative assignments based on limited information from which to determine the indicator status.
