Removing Weeds

Know what is a Weed and what is not

Pest plants that are a significant threat to the natural environment and agriculture are called declared plants. If these pest plants pose a nationally significant threat they will be referred to as WONS (Weeds of National Significance).
Landowners have a responsibility in the management of declared weeds. More information about declared plants you may find in the Sixth Creek catchment can be found on the Primary Industries and Regions SA (PIRSA) website.

Weeds in the Sixth Creek catchment are a major threat to all landholders in the area. They:

  • choke out watercourses
  • destroy native vegetation
  • impact on agriculture viability
  • are a major cause of bushfires, and
  • provide shelter for feral animals such as rabbits and foxes

Other indirect impacts caused by weed invasion are soil erosion, land slips and reduced water quality.

One of the main setbacks to weed control in the catchment is the steep and inaccessible nature of much of the land. This makes access with conventional weed control equipment difficult. The Group have developed strategies for controlling weeds in these areas and incorporates them into an annual on ground works program. It is important for landholders to understand that weed control is a long-term process requiring follow up work over many years to achieve successful results.

Landowners in the Sixth Creek Catchment and living adjacent to the riparian zones may find any of the following more common pest plants on their properties.

Allepo Pines
Blackberry Rubus spp.
Broom Cape/Montpellier
