A NEW infestation of Khaki weed has been identified just south of Keith, with Natural Resources South East urging residents to be wary of the invasive species.
The infestation has been treated and landowners in the vicinity notified, with Natural Resources South East officer Tony Richman – who identified the large roadside strip – continuing to monitor the area.
“Inspections of treated sites are necessary for at least three years to prevent reinfestation,” Mr Richman said.
“The recent find is concerning because it indicates that Khaki weed is finding its way into the region.”
Native to South America, Khaki weed is a summer-growing perennial with broad leaves and straw-coloured burrs around a centimetre long.
When established, it forms a dense carpet and its sharp burrs can be harmful to wildlife, stock and people.
“Khaki weed burrs also contain a considerable amount of seed, which is easily transported,” Mr Richman said.
“The best strategy for landholders is to recognise and control infestations before they set seed and become established.”
Small infestations can be dug out by hand and care must be taken to ensure the taproot is completely removed from the soil.
All plant material must then be placed in thick plastic bags ready for deep burial, or to transport for burning.
“As Khaki weed is a declared weed under the NRM Act, landholders are required by law to destroy infestations and to notify us if it is on their property,” Mr Richman said.
“NRM officers are available to assist with identification and advice on the best control methods.”
