African Boxthorn

African Boxthorn, Lycium ferocissimum, arrived in Geraldton in 1895 when Mr Henry Sewell bought seeds from a South Australian seed merchant. 

The long spines and dense growth of the plant made it a perfect stock fence in a harsh, isolated environment.  As with many introduced species, it has become a significant environmental problem.

Managing Boxthorn

The City of Greater Geraldton is systematically treating boxthorn, a Weed of National Significance, in high value natural areas using specialised machinery designed and built by a local company. 

Treated areas are then revegetated with local provenance plants grown by volunteers at the Geraldton Community Nursery. Boxthorn information booklet here

To assist with follow up treatment of small plants and monitoring, the City host regular onsite ‘Boxthorn Blitz' workshops and distributes 'Boxthorn Blitz Bags’ to workshop participants.  These arm members of the community with the knowledge and tools to safely treat small boxthorn plants, in natural areas, and on their own properties.
