Weed Spraying
Weeds pose a significant threat to biodiversity within the Shire of Irwin. If left untreated, weed species can rapidly spread invading agricultural farm-land and natural environments, impacting on agricultural productivity, recreation, tourism and human health.
The Shire uses a range of methods to manage weed species within the region including the use of herbicides that comply with the Health (Pesticide) Regulations 2011. These regulations primarily relate to signage, notification and licensing.
Landholders responsibIlities
All landholders, including Council, have a responsibility to manage weeds and pests on their own properties. As weeds have no regard for boundaries, a cooperative and proactive approach by all landowners is essential to control and minimise the spread. The Shire urges that action is taken for the removal of these species if they are identified on properties or verges which will support the Shire’s efforts to decrease any further advancement into natural bushland areas or into neighbouring properties.
Weed eradication programs
The Shire undertakes targeted control measures to manage the growth and spread on Council-owned and managed land. Scheduled weed eradication programs for roadsides, and several reserves within the Shire take place to ensure asset protection, road user safety, fire mitigation as well as to control any introduced weed species.
The Shire aims to minimise the use of herbicides where possible. By frequently undertaking weed management on your own verge and keeping the verge well maintained, residents can actively assist the Shire and alleviate the need to spray the verge. This will assist with reducing the application of herbicide in front of your property.
