Weed control at Wunambal Gaambera

Published 06 Feb 2019 by Wunambal Gaambera Aboriginal Corporation

Last month, Uunguu Rangers spent a week doing weed patrol at Ngauwudu (Mitchell Plateau).

Wunambal Gaambera country is largely weed free and pristine but there are incursions of weeds like shrubby stylo, mintweed and grader grass along roadsides and near campgrounds and settlements.

Some of these weeds probably entered years ago during mining exploration activity while others come in annually with vehicles, campers and road works.

Passiflora foetida is the only weed that has established itself in the bush. It was first recorded in Northern Australia in 1892 and, eaten by birds, has been spread widely across Northern Australia. The CSIRO is working on options for biological control.

Uunguu Rangers have been doing weed control for many years, often in partnership with rangers from parks and wildlife. This hard work is paying off and weeds are being contained to roadsides but annual patrols will always be needed to stop new outbreaks before they spread into the bush.

Keeping country weed free is one of the main objectives of the Wunambal Gaambera Healthy Country Plan.

The wet has been late but rain from Cyclone Riley passed during field work making it difficult to get out by charter plane.

Removing Paterson's Curse

With its vibrant purple flowers, Paterson’s Curse is often mistaken for a native wildflower but is in fact one of the most conspicuous weeds in paddocks and roadsides throughout Australia. Supposedly named after the Paterson family of Cumberoona, New South Wales - who planted it in their garden in the 1880s – the weed is now highly competitive in disturbed land, competing with agricultural crops and pastures, and unique and fragile native species. It was introduced to Australia from Europe.
