Biosecurity Alert – Prohibited Matter Detected

Published on 17 July 2023

Routine property inspections have detected Frogbit in the Narrabri Shire.

Frogbit (Limnobium Laevigatum) is a Prohibited Matter under the Biosecurity Act 2015. Frogbit is a perennial fast-growing, floating, aquatic plant. The invasive weed invades and smothers waterways, blocking irrigation channels, limiting recreational activities, and reducing light, food, and shelter for aquatic animals. Additionally, it creates dangerous conditions by hiding the water surface and making it appear like firm ground. It is illegal to buy, trade or sell Frogbit.

Council encourages all residents across the Narrabri Shire to familiarise themselves with the identification of Frogbit and report any suspicious weeds to Council as a priority. Residents can use the Department of Primary Industries NSW WeedWise website additional information regarding Frogbit.

For identification, to report possible sites or to find out further information, please contact Council’s Biosecurity Officers on 02 6799 6866.
