Weed Management

Join the war on weeds!

Environmental weeds are plants 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

  • Outcompete 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 in the City of Melville

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 our Natural Area Asset Management Plan. Please see our Weed Control Guidelines for more information.

Bushlands and Reserves- 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.

Current Spraying:

  • 11th and 12th May 2017 - Bushland Perimeter spraying being carried out in Leeming reserves including, Phillip Jane, Bill Brown, George Welby and Ron Carroll. 
  • 11th May 2017 - Ken Hurst Reserve

Foreshore Weed Control

With the assistance of qualified bushland contractors, the City of Melville will be undertaking herbicide control to manage weeds along the City’s Foreshore areas from Monday the 15th of May 2017.  Weed control will be carried out from Bicton through to Mt Pleasant.  These works will be completed within a 2 week period, weather dependant.

Target species will include grass weeds such as Kikuyu and Couch using a grass specific herbicide named Targa. A buffer treatment between sedges and path edges will also be created using Round Up® Biactive.  This will assist with improving the overall health of the City’s Foreshore areas as well as identifying areas which require further revegetation works.

Appropriate signage will be displayed on vehicles and in other strategic locations while works are occurring.  Contractors will be using current Best Management Practices to avoid any off-target damage.  The inclusion of dyes with herbicides will assist in identifying areas that have been treated.

For more information spraying times and locations, please contact the Environmental Maintenance Supervisor on 9364 0792.

Parks - Annual Weed Control Program

The City of Melville Parks team, with the assistance of authorized spray contractors, undertakes 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 – September pending weather conditions);

  • Appropriate signage will be displayed on vehicles and in strategic locations while works are in progress stating the chemical name.
  • Staff and contractors will be using current Best Management Practices to avoid any off-target damage.

Current Spraying: not currently spraying

For more information of spraying times and locations for the broadleaf weed control program, please contact the City’s Reserves East Maintenance Coordinator, David Prier, on 9364 0730.

 

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

  • Appropriate signage will be displayed on vehicles while works are in progress stating the chemical name.
  • Staff and contractors will be using current Best Management Practices to avoid any off-target damage.

Current Spraying:

-     Somerville Boulevard verge (Murdoch Drive to North Lake Road) between footpath and road.

Specific Herbicide Information

Specific herbicides used in the program include: 

  • Targa, a grass specific herbicide, is used to target grass weeds such as Perennial Veldt Grass in bushlands.
  • Round Up® Biactive and Metsulfuron is used to target bulbous and spring growing weeds in bushlands.
  • Spearhead, a broadleaf weed specific herbicide, is used to target grass weeds such as Bindii, Clover, Capeweed in parklands.
  • A glyphosate based herbicide is used to target annual and perennial weeds within the road reserve.

Before applying herbicide treatments, 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.
