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 re-vegetation guides, that can be found on the Shire Nursery 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.
