ONCE again woody weeds are booming across the Mansfield Shire.

Species like blackberry, briar rose, broom, gorse and thistle are causing significant problems for farmers and landholders alike.

Among these, blackberry is particularly invasive, posing both environmental and agricultural threats.

Blackberry thickets not only out-compete native vegetation and pastures but also provide shelter for pest species such as rabbits, deer, and foxes.

Access to watercourses is restricted for grazing animals, while the sharp thorns and dense growth decrease the land’s usability and increase fire risks from dead canes.

According to Up2Us Landcare Facilitator Kim Magnay, the impacts go beyond the environment.

“Blackberry chokes watercourses, reducing access and overall amenity, while increasing fire risk.

"For landholders, this adds stress and diminishes the landscape’s value,” she said.

If woody weeds are spreading on your property, it’s time to act.

Physical removal works for small infestations, while a spraying program is recommended for larger areas.

Spraying is most effective between November and April, avoiding frost periods.
