![]() ![]() Plant Assessment Form - Information gathered by Cal-IPC on the impacts, rate of spread, and distribution of invasive plants in California. -* – This plant is included in the CCR Section 4500 list of California State Noxious Weeds, but is otherwise not rated. ![]() * – An asterisk next to the rating indicates that a plant is included in the CCR Section 4500 list of California State Noxious Weeds.Q – An organism or disorder suspected to be of economic or environmental detriment, but whose status is uncertain because of incomplete identification or inadequate information.D – An organism known to be of little or no economic or environmental detriment, to have an extremely low likelihood of weediness, or is known to be a parasite or predator.C – A pest of known economic or environmental detriment and, if present in California, it is usually widespread.B – A pest of known economic or environmental detriment and, if present in California, it is of limited distribution.A – A pest of known economic or environmental detriment and is either not known to be established in California or it is present in a limited distribution that allows for the possibility of eradication or successful containment.Watch – These species have been assessed as posing a high risk of becoming invasive in the future in California.Alert – An Alert is listed on species with High or Moderate impacts that have limited distribution in California, but may have the potential to spread much further.Ecological amplitude and distribution are generally limited, but these species may be locally persistent and problematic. Their reproductive biology and other attributes result in low to moderate rates of invasiveness. ![]()
