Weeds

Environmental Weeds are widely recognised as a major threat to the biodiversity values of the South West.

Environmental weeds negatively impact bushland by:

  • Displacing native plant species through competition for space, water and nutrients.
  • Reduce wildlife habitat values.
  • Increase fuel loads for fire risk.

The City of Busselton is actively undertaking weed control works in bushland reserve areas and other natural areas throughout the City. The development of the Strategic Weed Action Plan 2021 is assisting to guide the City’s weed program by:

  • Prioritising weed species and priority areas for weed control.
  • Compiling weed mapping data.
  • Building community capacity through the Friends of Reserve Program on weed mapping and control.

Join the Arum Lily Blitz Description of image

Arum Lily (Zantedeschia aethiopica) originates from South Africa and is a major weed in the region.

  • Arum Lilies infest native bush, wetlands and agricultural areas.
  • Many landholders in the district are already controlling Arum Lily on their properties.
  • The City of Busselton also identifies areas of land it manages to undertake control each year.
  • A continued and combined approach is the best way to successfully control Arum Lily as seeds are easily spread by birds to new areas.

Nature Conservation Margaret River and the Department of Biodiversity, Conservation and Attraction are coordinating the Arum Lily Blitz control program funded by the State Government’s Natural Resources Management Program.

  • The project is supported by the City of Busselton, Shire of Augusta Margaret River, Lower Blackwood LCDC, Yallingup LCDC and the Margaret River Tourism Association.
  • Residents are strongly encouraged to join in and will be provided with free herbicide, resources, training and support.

Woody Weeds 

Woody weeds have become a significant problem in natural areas in the City of Busselton.

  • Eastern State natives including Sydney Golden Wattle (Acacia longifolia) and Flinders Ranges Wattle (Acacia iteaphylla) are particularly dominant.
  • These wattles and other woody weeds such as Milkwort (Polygala myrtifolia), Sweet Pittosporum (Pittosporum undulatum) and eastern states Gum trees (Eucalyptus species) are widely available in nurseries and have been planted in gardens, rural residential areas and farming properties.
  • They have spread readily into bushland, roadsides and degraded sites.
