Also known as: browntop bent, brown top bent

Brown-top bent is an invasive perennial grass introduced as a turf species, and now considered an environmental weed in parts of southern Australia.

Profile

How does this weed affect you?

Brown-top bent is a perennial grass that is native to northern Africa, the Canary Islands, Europe and parts of western and central Asia. It has been widely grown as a turf species in southern Australia, and is now considered an environmental weed in Victoria, New South Wales, South Australia, Western Australia and Tasmania, as well as an invasive weed of pastures and disturbed areas.

In New South Wales, it competes with native species in bog and fern communities of montane peatlands and swamps, and is common in disturbed areas in the sub-alpine and alpine areas of Kosciuszko National Park. It also has the ability to invade dry coastal vegetation, heathlands, grasslands, woodlands, sclerophyll forests, and riparian vegetation.

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.
North West Regional Recommended Measure*
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.
