Agriculture Minister Joe Helper said boneseed (Chrysanthemoides monilifera ssp. Monilifera) was one of Australia's 20 Weeds of National Significance.

"Boneseed has already severely impacted bushland in parts of Eastern Australia, so its eradication in Lake Boga and Tresco is vital," Mr Helper said.

"While the weed is not an agricultural threat, its ability to regenerate quickly and compete with native species, particularly after fire, means it can have a devastating effect on our native bushland and Victoria’s unique biodiversity.

"Boneseed is not currently widely distributed in the North Central region. However it has the capacity to spread further if left unchecked."

Department of Primary Industries (DPI) pest management officer Heath Dunstan said the woody shrub could be up to three metres tall, flowers during Spring and is easily distinguished by its yellow 'daisy like' flowers and vivid green foliage.

"We're currently urging landholders and the wider community to report any sightings of the weed so we can work together and eradicate the infestations while they remain small and manageable," Mr Dunstan said.

"Over the next four years, the DPI will target the weed, seeking to eradicate it from the local landscape."

As part of the Noxious Weed Review, the Victorian Government recently reviewed the list of declared noxious weeds in Victoria.

Boneseed is now one of seven regionally prohibited species in the North Central Catchment, putting it among the highest threats to regional biosecurity.

Under the Catchment and Landscape Protection Act, Boneseed’s Regionally Prohibited Weed status in the North Central Catchment requires landowners to eradicate the plant as soon as possible.
