Chilean Needle Grass Alert in Gilmore Valley
Published on 20 October 2020
Landholders in the Gilmore Valley Region are advised that a Chilean Needle Grass (Nassella neesiana) outbreak has been identified which affects the areas between the Snowy Mountains Highway/Batlow Turnoff, properties along the East and West Gilmore Roads, and all properties along the old Rail Line to Batlow.
Farmers and graziers in this area are encouraged to check their stock and lands regularly to prevent the spread of the weed as well as your investment in livestock.
The infestation was found by a diligent local land holder who immediately reported an unknown grass which was identified as Chilean Needle Grass (CNG). A preliminary survey identified a significant infestation affecting much of the burned grass and bushland in the defined area.
CNG poses a potentially serious threat to primary production and the environment. It is not widely distributed in the area but is likely to spread if not effectively controlled.
CNG is regarded as one of the worst weeds in Australia due to its invasiveness tendencies, potential for spread, and economic and environmental impacts. It is closely related to another Weed of National Significance - serrated tussock (Nassella trichotoma).
The grass grows in tussocks about 1 m high and it can be identified by its flowering seed heads which are a distinctive purplish colour and its seeds which are very sharp at the point. More information can be found on the NSW Weedwise website at: weeds.dpi.nsw.gov.au/Weeds/ChileanNeedleGrass.
CNG affects both sown pasture and native grasslands. It is relatively unpalatable and reduces farm productivity by displacing more desirable pasture species. Heavy infestations can decrease productivity by as much as 50%. It also causes injury to stock and downgrades wool, skins and hides with its long, sharp seeds.
CNG reduces biodiversity in native grasslands, where it out competes with indigenous species. The average annual cost of controlling CNG can be between $60 and $120 per hectare, depending on infestation density.
Local Land Services is currently providing up to $5,000 grants for weed control, including Chilean Needlegrass, for landholders who were impacted by the Dunn’s Road and Green Valley bushfires. Applications close on 30 October, 2020. Contact Project Officer, Keeley Warren on 0437 219 152 for more information.
