Cane needle grass (Nassella hyalina)

Cane needle grass is a tussock-forming grass. It is drought tolerant and forms dense, competitive infestations.

Profile

How does this weed affect you?

Cane needle grass is drought tolerant and forms dense, competitive infestations. It is closely related to serrated tussock which costs southeastern Australia’s grazing industries more than $40 million annually in control expenditure and lost production. Several species of Nassella have proven difficult to control and have continued to spread since their introduction into Australia, and are now environmental and agricultural weeds.

What does it look like?

Cane needle grass is a perennial grass that grows in clumps up to 120 cm tall. The long, upright flower stems look like canes. Seeds have a twisted tail that sticks out from the flower spikelet. Plants flower in spring and summer.

Where is it found?

Cane needle grass is found in New South Wales and Victoria. It was first recorded on the northern tablelands of NSW in 1951.

It is native to South America.

Maps and records

  • Recorded presence of Cane needle grass during property inspections (Map: Biosecurity Information System - Weeds, 2017-2022)
    These records are made by authorised officers during property inspections under the Biosecurity Act 2015. Officers record the presence of priority weeds in their council area and provide this to the NSW Department of Primary Industries. Records reflect the presence of the weed on the date of inspection.

  • Estimated distribution of Cane needle grass in NSW (Map: NSW Noxious Weed Local Control Authorities, 2010)
    Map shows weed distribution and density estimated by local council weeds officers in 2010.

How does it spread?

Sharp seeds attach to clothing, fur, machinery and vehicles.

Seed can also be spread via wind and water and in contaminated fodder and soil.

Biosecurity duty

The content provided here is for information purposes only and is taken from the Biosecurity Act 2015 and its subordinate legislation, and the Regional Strategic Weed Management Plans (published by each Local Land Services region in NSW). It describes the state and regional priorities for weeds in New South Wales, Australia.

Area Duty
All of NSW General Biosecurity Duty
All plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable.
Riverina
Eradication zone: whole region except for the containment zone of Wagga Wagga City Council
Regional Recommended Measure* (for Regional Priority - Eradication)
Eradication zone: The plant should be eradicated from the land and the land kept free of the plant. Containment zone: Land managers should prevent spread from their land. Whole region: managers should mitigate the risk of new weeds being introduced to their land. The plant should not be bought, sold, grown, carried or released into the environment.
South East Regional Recommended Measure* (for Regional Priority - Eradication)
Land managers should mitigate the risk of new weeds being introduced to their land. The plant should be eradicated from the land and the land kept free of the plant. The plant should not be bought, sold, grown, carried or released into the environment. Notify local control authority if found.
