African Boxthorn (Lycium ferocissimum), was introduced from South Africa to provide hedges and windbreaks but has now been classified a Weed of National Significance. African Boxthorn has become a major threat to biodiversity because it outcompetes native flora and alters the habitat by forming dense impenetrable thickets. It has spread rapidly since its introduction because it produces appealing red berries that are eaten by both native and non-native fauna.
Boxthorn has become well established in coastal dunes and along riparian habitats between Hutt and Irwin Rivers. NACC is focusing control efforts at some key sites within these areas, one of which is the Irwin Estuary within the Shire of Irwin where boxthorn infestations have impacted on recreational and aesthetic values. Following boxthorn removal, the local community have risen to the challenge of pulling out boxthorn seedlings and assisting with revegetation.

NACC has additional boxthorn removal programs in the Shires of Chapman Valley and Northampton, and has funded similar works in the City of Greater Geraldton.
In response to community enquiries, NACC is developing a boxthorn removal incentive program, which will provide some financial support to landholders who wish to remove this aggressive weed from their property. More information about the incentive program will be available soon..
