Grader Grass Weed Management Plan

Share on Facebook Share on Twitter Share on Linkedin Email this link

The Northern Territory Weed Management Branch is reviewing the statutory Weed Management Plan for Grader Grass (Themeda quadrivalvis) 2016.

Grader grass is an annual, and sometimes perennial grass which can grow to a height of 2 meters. It is native to India and was accidently introduced to the Northern Territory in the 1960s as a contaminant in pasture seeds.

Grader grass is a prolific seeder and seeds can often germinate year round in moist areas. Grader grass is capable of invading native bushland, roadsides and disturbed or overgrazed areas. Stock may graze young plants but find mature grader grass unpalatable. If grader grass becomes dominant in a pasture there is loss of productivity, and the potential for increased fire risk. It can form dense monocultures preventing native species from germinating and persisting.

Please provide your feedback on the review of the: Weed Management Plan for Grader Grass (Themeda quadrivalvis) 2016.

Contributions to this consultation are now closed for evaluation and review.
