A tiny invasive wood borer has been discovered at Hyde Park.

About the size of a sesame seed, the Polyphagous shot-hole borer (PSHB) excavates tunnels in trees and there they cultivate fungus as a food source. This fungus spreads in the tunnels disrupting the flow of water and nutrients.

There is no known effective chemical treatment for PSHB, so the City of Vincent has been working with the Department of Primary Industries and Regional Development (DPIRD) to manage infested trees through the removal of infested material.  

Pruning of infested trees is scheduled to take place on Thursday 2 February and Friday 3 February to remove infested material, to prevent further spread to neighbouring trees and to minimise the risk falling tree limbs may pose to people visiting the park.

Work will be conducted by certified arborists supervised by DPIRD and City of Vincent staff. We apologise for any inconvenience during this time.

The water playground may be closed for a short period of time by DPIRD.

For everyone’s safety, please stay away from the active work zones.

Residents in the PSHB Quarantine Area are encouraged to inspect their backyard trees for signs of borer damage and/or tree dieback.

Please report signs of borer damage to the MyPestGuide reporter app or the Pest and Disease Information Service on +61 (0)8 9368 3080, email padis@dpird.wa.gov.au.
