Narrow leaf cotton bush (Gomphocarpus fruticosus) is a concern for many landholders and is declared under the Biosecurity and Agriculture Management Act 2007 (BAM Act). It is in the C3 management category, which requires landholders to control to minimise its spread.
Management of cotton bush is best achieved through a community coordinated approach. The Department of Agriculture and Food, Western Australia (DAFWA) is working with community to develop operational plans that include community expectations, responsibilities and compliance measures. The Peel-Harvey and Leschenault biosecurity groups are raising awareness and engaging community for actions to control cotton bush.
DAFWA is supporting biosecurity groups and has identified high priority areas for compliance.
DAFWA has prepared a compliance strategy which is being implemented over the coming summer months. DAFWA staff are currently undertaking inspections for cotton bush compliance in the Peel-Harvey and Leschenault catchment areas.
The department will undertake compliance processes in a way that supports a community coordinated approach for control and management of widespread and established declared pests.
The compliance process includes remedial action and prosecution where appropriate.
