Boneseed tackled to protect native vegetation

The treatment of Boneseed infestations at seven priority sites throughout the Sunraysia region has resulted in the protection of over 11,600 ha of high value native vegetation.

Boneseed, classified as one of 32 Weeds of National Significance (WoNS), is a serious threat to the Mallee environment. It overruns native vegetation and reduces habitat for native animals with a significant potential to spread.

Boneseed is a prolific seeder and seeds are readily eaten by birds and animals. The seeds readily germinate following dispersal and soil disturbance. 

Mallee CMA Board Chairperson Sharyon Peart said that the Victorian Mallee is considered a high priority region for boneseed and control efforts will help to establish containment of existing weed populations. 

Ms Peart said Boneseed plants were treated when they were not in seed to prevent boneseed from spreading beyond the edges of the main populations. 

Boneseed control works were undertaken by local contractors at Red Cliffs and Cardross for the protection of native vegetation.  Works occurred across a variety of public land tenures including Mildura Rural City Council, Department of Environment and Primary Industries, Lower Murray Water, Vic Roads, Vic Track and V/Line. 

Mallee CMA contractors completed most control works. However, Vic Roads and V/Line opted to undertake their own control having had a budget set aside for weed control. 

Infestations were located in intact remnant vegetation and comprised of both mature and immature plants.  Large plants were cut and painted with chemical, whilst juvenile plants were hand pulled and foliaged sprayed.

Land managers participating in this program have scheduled follow-up treatment in the 2013/14 financial year to target any regeneration that may occur. .

Funding for this program was provided from the Australian Government’s Caring for Our Country.
