Lobed needle grass poses a significant threat to biodiversity and agricultural productivity. It is classed as a ‘State prohibited weed’ under law meaning that it is considered to be among the highest category of noxious weeds in our State but one which is still capable of being eradicated.1 Since 2012 the State Government has taken no action to eradicate lobed needle grass despite having a statutory duty to take reasonable steps to do so.
