Weed profile: Chilean needle grass - Weed of National Significance
Chilean needle grass
Chilean needle grass (Nassella neesiana) is closely related to serrated tussock (Nassella trichotoma). Chilean needle grass affects both sown pasture and native grasslands of southeastern Australia. It is relatively unpalatable and reduces farm productivity by displacing more desirable pasture species. Heavy infestations can decrease productivity by as much as 50% during summer. It also causes injury to stock and downgrades wool, skins and hides with its long, sharp seeds.
