Chilean Needle Grass

On 5 November 2021, Authority staff identified a significant roadside infestation of the invasive grass species Chilean Needle Grass (Nassella neesiana) on the Hunter Road, east of Gundy (Upper Hunter Shire LGA). This is the first recorded infestation of this plant in the Upper Hunter. 

In pastures which have been invaded by this grass, production can reduced by half with stock at risk of receiving eye and hide injuries.  It can also effect meat quality, downgrade wool and reduces biodiversity.

Chilean Needle Grass grows in tussocks about a 1m high with the seed heads having purple glumes and long bent awns. Identification and other information can be found on the NSW DPI Weedwise website by clicking on this Link
