Acacia baileyana

Common names: cootamundra wattle

Acacia baileyana (cootamunda wattle) is a shrub (family Fabaceae) with yellow flowers and finely dissected leaves found in the coastal ranges, San Francisco Bay area and transverse ranges of California. It is native to Southeastern Australia. It favors scrub and chaparral habitat. It has long-lived seeds that accumulate in the soil and germinate after fires, hot weather or other disturbances. It spreads via ants, wind, water and dumped garden waste.

Cal-IPC Rating: Watch

CDFA Rating: None?

Explanation of CDFA ratings

• 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.
• B – A pest of known economic or environmental detriment and, if present in California, it is of limited distribution.
• C – A pest of known economic or environmental detriment and, if present in California, it is usually widespread.
• 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.
• 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.
• * – An asterisk next to the rating indicates that a plant is included in the CCR Section 4500 list of California State Noxious Weeds.
• -* – This plant is included in the CCR Section 4500 list of California State Noxious Weeds, but is otherwise not rated.
