Chilean Needle Grass - One Of Australia’s Worse Weeds
Chilean needle grass is a Weed of National Significance because of its invasive nature, potential for spread and economic and environmental impacts.
Named for its sharp, pointed seeds, it affects pastures and native grasslands. The long, sharp seeds can cause injury to animals and downgrade lamb and sheep meat, wool, skins and hides.
Chilean needle grass reduces natural biodiversity by replacing native species within native grasslands, grassy woodlands and riparian areas. It tolerates drought, heavy grazing and periodic inundation.
This grass has been found on the Darling Downs in southern Queensland.
Currently monitoring is being carried out along the roadside just south of Allora for Chilean Needle grass.
Southern Downs Regional Council undertakes control of declared weeds on its lands such as roads and reserves. Control of weeds on roads that are fenced into private property (unfenced roads) is the responsibility of the property owner.
Chilean needle grass, unlike many other weeds, has little ability to spread on the wind.
The main method of spread is human-assisted such as -
it adheres to clothing, livestock, vehicles and farm machinery
it can be found in contaminated seeds or fodder
it is transported by slashers and earthmoving equipment.
If you have weeds encroaching onto your property from adjacent land or are concerned weeds are not being managed in an area, please report it to Southern Downs Regional Council so action can be taken.
Early detection is the cheapest form of weed control!
