Weed Management

Weeds in Central Australia are an extremely serious threat to biodiversity in the region.

The CLC Rangers and Regional Land Management staff carry out control work for a variety of declared weeds in conjunction with traditional owners and other Indigenous land managers.

The priority weed species that CLC focuses on are:

  • Athel Pine (a Weed of National Significance) 
  • Parkinsonia (a Weed of National Significance) 
  • Prickly Pear (a declared weed in the NT) 
  • Rubber Bush (a declared weed in the NT) 
  • Buffel Grass (a widespread environmental weed in the region)
  • Mexican Poppy (a declared weed in the NT) )

The CLC’s ranger groups have undertaken a range of accredited courses in the safe and effective use of chemicals to control weeds, and use a combination of chemical and manual (chainsaw cutting) removal techniques to address weed threats.

Ranger groups have to make strategic decisions about which weed species to address as a priority, and therefore tend to focus on populations threatening important natural and cultural assets first, and then try to take a catchment-based approach to weed management – treating weeds in upstream locations first before tackling bigger infestations around communities
