Noogoora burr (Xanthium strumarium) is one of the most serious and widespread weeds in the world. It is mainly found in areas with high rainfall and a temperate climate but it may also persist in arid environments, where the seeds may remain dormant for years and then take advantage of occasional rainfall to reproduce.
Noogoora burr is a declared pest for the whole of Western Australia, control category C3 (Management) in the Kimberley and C2 (Eradication) for the remainder of the state. Infestations have been detected in the Pilbara region (DeGrey River catchment), Perth and near Denmark on the south coast.
The Department of Primary Industries and Regional Development are encouraging community members to report suspected sightings to the MyPestGuide® Reporter via the app or online (mypestguide.agric.wa.gov.au). Prompt action is necessary to assist in eradication, please note the date, time and location of the pest and take photographs (if possible).
