Speaking today, Senior Weeds and Pest Management Officer Graham Prichard said the weed posed a threat to animal life and wetlands in Port Stephens.
"As well as being toxic to horses, cattle and sheep, Groundsel Bush can form dense stands that vehicles and animals cannot pass through," he said.
"A native of eastern North America and the West Indies, the Groundsel Bush can degrade the natural environment by transforming saltmarshes and wetlands into heavily wooded bogs."
"Isolated plants have been found at Tomago, Raymond Terrace, Glen Oak, Twelve Mile Creek and Bobs Farm during the last two years. While all these plants have been eradicated, it is likely more plants are waiting to be found," Mr Prichard said.
The weed can be easily spread over large distances by strong winds and human activity.
"The bush is also very hardy, tolerating frosts, salt and acid sulphate soils, drought and water logging," he said.
Landholders are asked to look out for and report possible Groundsel Bush plants. Key features for identification are;
· Dense upright bushes or trees
· Leaves are a light and bright green colour with toothed edges similar to holly
· Male and female plants separate
· Female plants covered in white fluffy seeds around April/May
· Stems thick, tough, bark striped, dark to black
· Usually growing in wetter areas
Suspect plants can be reported to Graham Prichard on 49800392
