The Department of Primary Industry & Regional Development (DPIRD) has alerted the City to a positive detection of the Polyphagous Shot Hole Borer (PSHB) in four Coral Tree’s (Erythrina x sykesii) within Richardson Reserve in South Perth. 

The infestation is at an advanced stage where all four trees will need to be removed.

The area is now PSHB quarantine zones, which means that plant material larger than 2cm wide cannot be removed. These areas are still open to the public as normal. 

Quarantine will remain in effect for at least 12 months and surrounding residents will receive a letter drop regarding further treatment.

PSHB is a beetle native to Southeast Asia. The beetle attacks a wide range of plants by tunnelling into trunks, stems and branches.
