The California Invasive Plant Inventory includes plants that are deemed a potential threat to the state's wildlands. The list (as amended over time), was prepared by the California Invasive Plant Council, and represents the best available information from invasive plant experts in the State of California. Inclusion on the list is based on an assessment of the ecological impacts of each plant, and ratings represent cumulative impacts statewide rather than by individual region.
