Parkes Shire Council is calling on all residents to be vigilant in identifying and reporting African boxthorn (Lycium ferocissimum), one of the most invasive and damaging weeds threatening the region's environment, agriculture, and biodiversity.
Native to southern Africa and introduced to Australia in the mid-1800s, African boxthorn has become a widespread and destructive pest species. It forms dense, thorny thickets that can reach up to 5 metres in height, hindering access for both livestock and people, outcompeting native plants, degrading bushland, and providing shelter for invasive animals such as rabbits and foxes.
Michael Chambers, Environment and Sustainability Manager at Parkes Shire Council, highlighted the threat posed by plants like African boxthorn.
"This plant is extremely versatile and thrives in a wide range of climates and ecosystems," Mr Chambers said.
"African boxthorn is one of the worst weeds in Australia due to its invasiveness and the serious economic and environmental impacts it causes."
African boxthorn is a listed Weed of National Significance (WONS) and is considered a Priority Weed in New South Wales. It reduces agricultural productivity, is toxic to humans and animals, and spreads rapidly through birds, water, vehicles, and dumped garden waste. It significantly alters native ecosystems and displaces biodiversity.
The plant is easily identified by its pale lilac to white tubular flowers with purple blotches, bright green teardrop-shaped leaves, and small orange to red berries about one centimetre in diameter. The plant's dense and spiny growth makes it an impenetrable barrier, with older branches developing ridged bark and sharp thorns.
Under the NSW Biosecurity Act 2015, landholders are legally obligated to control Priority Weeds such as African Boxthorn. Parkes Shire Council, as the Local Control Authority, actively inspects public and private lands and implements targeted programs to stop the spread of these high-risk weeds. Council's Biosecurity Team works closely with landholders, community groups, and partner agencies like Local Land Services and Transport NSW to monitor and control infestations.
Controlling African boxthorn requires a long-term approach, including physical removal, chemical treatments such as foliar sprays and basal bark application, and ongoing follow-up to eliminate regrowth. Prevention remains the most effective strategy, as early detection and prompt removal significantly reduce the risk of further spread.
"We're here to support the community in managing this weed, but lasting success depends on all of us working together," Mr Chambers added.
Residents are urged to report any sightings of African boxthorn, especially along roadsides, creek lines, and public reserves. Garden waste should never be dumped in natural areas, as this contributes to the spread.
