Environmental & Noxious Weeds
Why control weeds?
Environmental weeds are a major threat to our natural environment. Weeds can:
- Smother indigenous vegetation
- Prevent regeneration of indigenous plants
- Reduce habitat and displace native fauna
- Harbour pest animals such as rabbits and foxes
- Choke waterways, increasing flooding and reducing water quality
- Increase fire risk
- Alter hydrological and nutrient cycles.
Environmental and noxious weeds also impact agricultural production and can damage recreational, tourism and cultural values.
What you do counts!
Controlling environmental and noxious weeds on your property will help protect the peninsula’s unique natural environment – our coasts, creeks, bushland, national parks, rural landscape and urban green spaces.
Environmental and noxious weeds – what’s the difference?
Environmental weeds are plants that invade native vegetation and impact on the survival of indigenous plants and animals. Some environmental weeds, like Blackberry, are also declared noxious weeds.
Noxious weeds are plants which are listed under the state government’s Catchment and Land Protection Act 1994 (CaLP Act). These plants cause, or have the potential to cause, environmental or economic harm. Under this act, landowners have a legal obligation to manage declared noxious weeds on their land. The state government is responsible for monitoring and enforcing the CALP Act.
If you are concerned about a declared noxious weed on private property, contact Agriculture Victoria on 136 186 or visit the Agriculture Victoria website for more information.
How to reduce weeds
- Know your end goal.
- Correctly identify plants to avoid removing indigenous species.
- Select a control method that is suitable for the species and the situation.
- Timing is everything! Aim to control plants before they flower and set seed.
- Minimise soil disturbance to avoid potential weed spread and erosion.
- Target isolated weeds first, working towards larger infestations.
- Follow up is essential for effective weed control.
- Dispose of weeds appropriately – never dump garden waste over the back fence, in bushland or waterways.
- Weeds can be habitat too. Many small birds, like Superb Fairy-wrens and Eastern Spinebills, use weedy shrubs for shelter and nesting. Weed small patches at a time to minimise impact and replace with indigenous species to supplement habitat.
- Consider creating a wildlife friendly garden using local native plants suited to your area. To help you select local native plants that are suitable for your region, the Shire has developed a series of regional revegetation guides, that can be found on the Revegetation Plant Guides page.

Wait! You might need a planning permit
The removal of some weeds may require a planning permit. For more information see our page on vegetation removal.
How the Shire controls weeds on public land
Weed control is a community priority for environmental and economic reasons. Our weed management and control work are planned and carried out in line with feedback from our community.
Weeds are controlled to meet statutory requirements, improve open space aesthetics, protect biodiversity, provide consistent playing surfaces, protect productive land, keep clear lines of sight along roads, protect infrastructure from damage and free of obstruction.
Weeds are controlled in Shire-managed bushland reserves, passive recreation reserves, formal parks, garden beds, on roads, road reserves and shared pathways, sporting reserves, along curb and channel, on and near buildings.
We are committed to identify optimal combinations of pest and weed control methods for long term sustainability with the aim of preventing problems from occurring. Various methods are used including hand weeding in garden beds and bushland; motorised weeding for road shoulders and near creek crossings; reduced weed control in public areas around sports grounds; gas burner weeding in bushland reserves; steam weeding at The Briars; and where necessary and under strict controls we use herbicide.
Mornington Peninsula Shire takes all health and safety matters very seriously and is guided by Worksafe Victoria and the Australian Pesticides and Veterinary Medicines Authority (APVMA) on the use of herbicides. APVMA regulates the use of herbicides in Australia and considers all relevant scientific material when determining the likely impacts on human health and worker safety including long and short-term exposure to users. When used under strict health and safety measures, following the manufacturers’ instructions and applied by properly trained and experienced staff, herbicides are a safe and cost-effective method.
With support from our fantastic Friends Group volunteers and by implementing alternative methods, we are working to minimise the use of herbicides where practical. We will continue to research alternative organic weed killers and trial new products including plant-based acids and oils to reduce the use of herbicides.
