Declared plants

To protect Western Australian agriculture the Department of Primary Industries and Regional Development regulates harmful plants under the Biosecurity and Agriculture Management Act 2007.

Plants that are prevented entry into the State or have control or keeping requirements within the State are known as declared pests.

The Western Australian Organism List (WAOL) contains information on the area(s) in which a plant is declared and the control and keeping categories to which it has been assigned in WA.
