Noxious Weeds of Whitehorse

A noxious weed may be either an agricultural or an environmental weed. They cause problems in bushland reserves and gardens by invading and taking over from indigenous (naturally occurring) plant species, or preventing their regeneration and denying indigenous wildlife access to indigenous food and shelter which can lead to local extinction of our birds and animals.

There are four categories of noxious weeds defined under the Catchment and Land Protection Act 1994 (CaLP Act) and, under the Whitehorse City Council Community Local Law (2014) S4.2 ( PDF 202.61KB), "An owner or occupier of land must not allow any vermin or noxious weeds to exist on the land".

The noxious weed categories are as follows:
