Protect our trees, protect our City

A free Polyphagous shot-hole borer (PSHB) information session is being held at the City of Wanneroo’s Civic Centre on Saturday 14 June.

Join us to discover more about the PSHB, the threat it poses to our urban canopy and how you can help stop the spread of this invasive pest.
First detected in Perth in 2021, the tiny wood-boring beetle has been detected in trees across Perth, with a quarantine notice quickly put in place to support the Department of Primary Industries and Regional Development’s (DPIRD) response.
The City is working closely with DPIRD to prevent the spread of the PSHB and encourages the community to use the MyPestGuide app to report suspected sightings.
The City of Wanneroo currently sits in Zone B of the Quarantine Area. This means residents:
- cannot move untreated or unseasoned wood outside the Quarantine Area, unless chipped to pieces that are 2.5 cm or less in diameter,
- cannot move plant materials, including living plants, that are greater than 2cm in diameter outside the Quarantine Area,
- must ensure any machinery used to handle green waste is cleaned before it can be moved outside the Quarantine Area, can move wood or plant materials, including living plants, into Zone A.
Bookings are essential, register here.
