Join the War on Weeds

Environmental weeds are plants which are not from the local area and can be highly invasive. Many weeds are introduced from abroad or even from other parts of Australia, escaping from gardens and invading our local urban areas and bushland.

Impacts of Weeds

  • Out compete native plants for water, nutrients, light and space, reducing the ability of native plants to survive alongside
  • Grow and reproduce rapidly due to a lack of natural herbivores and diseases in a new environment (in their native environment these things would control the population naturally)
  • Often weeds are not the right food source for the native animals and insects so affect the food chain and reduce food sources available
  • Can create a high fuel loading due high abundance of weeds, particularly grassy weeds.

Weed Management Practices

The City of Melville uses a number of techniques and strategies to control weeds for practical and effective long term outcomes, usually in combination, these include:

  • Hand weeding
  • Slashing/Brush cutting
  • Herbicide application
  • Injection of tree stumps.

Varying levels of weed control are carried out in bushland and foreshore reserves depending on their priority rating in the City's Natural Area Asset Management Plan.

Annual Weed Control Program

Bushlands - Annual Weed Control Program

The City of Melville Bushland staff, with the assistance of qualified bushland contractors, undertakes herbicide control to manage annual and perennial weeds in the City’s natural area reserves.

  • Appropriate signage will be displayed on vehicles and in strategic locations while works are in progress
  • Staff and contractors will be using current Best Management Practices to avoid any off-target damage
  • The inclusion of dyes with herbicides will be used to identify areas that have been treated.

Spraying Times and Locations

  • Week commencing 9th July 2018 - Ern Stapleton Reserve, Wal Hughes Reserve, Piney Lakes Reserve (Bushland areas), Harry Stickland Reserve, Harry Sandon Reserve, Dudley Hartree Reserve, Al Richardson Reserve, Reg Bourke Reserve, Richard Lewis Reserve, Tom Firth, Rob Weir Reserve, Jeff Joseph Reserve and Bull Creek Reserve.

Reserves - Annual Weed Control Program

The City's reserves team, with the assistance of authorised spray contractors, undertake selective herbicide control to manage broadleaf weeds in the City’s Active and Passive reserves. The City’s road reserves are treated with a non-selective herbicide; this includes kerb lines, footpaths, medians, round-abouts and buffer zones.

During the course of our broadleaf weed control program (July to September each year, dependant on weather conditions), the following precautions are taken;

  • Appropriate signage is displayed on vehicles and in strategic locations while works are in progress, stating the chemical name being used
  • Staff and contractors use current Best Management Practice to avoid any off-target damage
  • Spraying may take place outside of July to September, dependent on weed infestation and weather conditions.

Streetscapes - Annual Weed Control Program

During the course of our streetscapes weed control program (throughout the year dependant on weather conditions);

  • Appropriate signage is displayed on vehicles while works are in progress, stating the chemical name being used
  • Staff and contractors use current Best Management Practices to avoid any off-target damage

  • Round Up® Biactive and Metsulfuron is used to target bulbous and spring growing weeds in bushlands
  • Destiny is a selective turf herbicide that offers selective grass and broadleaf weed control. Provides control of hard to kill weeds
  • Spearhead/Barricade, are broadleaf weed specific herbicides, used to target grass weeds such as Bindii, Clover, Capeweed in parks and reserves

Before applying herbicide treatments, the City of Melville has considered the impact of control options on co-occurring native flora including trees, shrubs, geophytes, grasses and other native herbs and on fauna. The methods and chemical concentrations that we employ are considered Best Practice Management.
