The BoQ said it believed the illegal clearing - behind the Crow’s Nest estate - occurred on Saturday 24 June, causing “considerable damage.”
Following two subsequent visits, DEECA officials have consented to signage and fencing being erected.
The matter has also been reported to the Conservation Regulators.
“Every case of vegetation vandalism costs ratepayers, and depending on the severity of the case, the cost to the community can be significant for investigation, signage, replacement, and remediation. However, the costs in terms of native habitat, visual, historical, and environmental value, and urban character, require far more effort and time to recover,” the BoQ said.
“Any person who is found responsible for vegetation vandalism is liable for prosecution and will be actively pursued for the recovery of costs, including fines under Council's Local Law, the Planning and Environment Act 1987, and the Flora and Fauna Guarantee Act 1988, if applicable.”
It has encouraged anybody with information about this incident to contact Council’s Local Laws team on 5258 1377.
