As the temperature warms up and the wet weather encourages grasses to grow, Yass Valley Council’s Biosecurity Weed Officers are stepping up to the important job of protecting the local environment from invasive grass weeds.

Yass Valley Council Senior Biosecurity Weeds Officer, Brett Lees, has been out spraying a localised infestation of Chilean needle grass at the entry of Murrumbateman Recreation Grounds.

“People entering the rec grounds from the main entrance, off the Barton Highway, may begin to notice the grass starting to turn yellow and die off,” Brett said. “This is because Council has been treating Chilean needle grass and other invasive weeds present.”

“Chilean needle grass is a serious weed of pastures that has a significant impact on carrying capacity, as well as dominating native grassland environments.”

“It is not palatable for stock, has very low digestibility and can cause wounds to livestock’s eyes, mouths and stomachs.”

“Most Chilean needle grass is already setting seed and in need of treatment,” he said. “An established infestation of mature Chilean needle grass is a very difficult and lengthy process to manage.”

Council’s Biosecurity Officers have erected signage notifying the public of the weed threat and which herbicides have been applied.

This is all part of a broader invasive weed control program that Council will be rolling out in the coming weeks. Initial control measures will target St John’s wort, blackberry and sweet briar.

Last financial year Council implemented a weed control program targeting invasive grass weeds, such as Chilean needle grass and woody weeds on Council land and roadsides.
