Willoughby City Council will launch a comprehensive investigation into a large-scale tree vandalism event along Willowie Road under the Environmental Planning and Assessment Act 1979.

As part of the investigations, rangers will be visiting residents through door-knocking and written communications throughout the coming weeks.

Under the Environmental Planning and Assessment Act 1979, a person who is found guilty of an offence involving the destruction of or damage to a tree or vegetation, in addition to recording a conviction and getting a substantial financial fine, might also be directed to plant new trees and vegetation and maintain those trees and vegetation to mature growth.

Council rangers actively pursue leads and conduct a thorough investigation to gather evidence.

Also, as part of an awareness campaign, banners will be erected in strategic locations to inform the community about the severity of the tree loss and its impact on precious wildlife.

Anyone with information related to this case or to report other incidents, contact Willoughby City Council at 02 9777 1000 or email to email@willoughby.nsw.gov.au.

Council is offering up to $10,000 as a reward for any information leading to a successful prosecution of those responsible.
