Boxthorn removal works being undertaken near the south bank of the Irwin River has created a hazard for walkers and cyclist. The Northern Agricultural Catchments Council (NACC) is cautioning people to take care in that area. Signs will be erected to advise people of the areas to avoid.

The management works to remove Boxthorn, a spikey invasive weed that is promant in the area, has resulted in sharp Boxthorn cut offs lying on the ground near the targetted river locations.

Coastal and Marine Program Coordinator Dr Mic Payne said, “Boxthorn is listed as a Weed of National Significance as it is agressively invasive, replacing native vegetation with dense, impenatrable thickets covered in large, sharp spines”. “It is important to revisit sites where boxthorn has been removed to ensure new seedlings are removed, hence this project will run over a number of years”.

Removed boxthorn has been stacked ready for burning or chipping.  Further boxthorn removal will take place in the coming weeks with the aim of completely eradicating it from around the estuary.

NACC will be holding a free Boxthorn Information and Weed Removal Session for private landowners around Dongara on the 1st of April at the Irwin Recreation Centre starting at 4pm. The session includes a practical demonstration by local contractors who have developed quick and safe methods for Boxthorn removal.
