Biosecurity Weeds

Weeds in North Sydney Council LGA

In Sydney's northern region many bushland reserves are under threat because of the invasion of plants escaping from backyards and gardens. Common garden species can be spread by birds eating the seed or people tossing garden clippings into the bush.

Some exotic species are vigorous invaders, growing faster than native species and usually producing much more seed.

Once weeds take over an area the character of the bushland changes, diminishing habitat for native wildlife and altering fire regimes.

At the community level, Bushcare groups work with Council to eradicate high risk weed infestations and regenerate bushland with indigenous species.

However, weeds do not recognise local government boundaries and to this end North Sydney Council is a member of the Regional Weeds Committee (Sydney North), which coordinates a regional approach to weed management.

 

Biosecurity Weeds Declarations for North Sydney Council

Weeds in North Sydney are categorised according to their Biosecurity Risk and ability to spread from their existing and or intended location. In North Sydney, Biosecurity Weeds (formerly referred to as Noxious Weeds) are categorised into 5 Risk Ratings which in-turn determine the control action required. Under the NSW Biosecurity Act 2015, all individuals have a “Biosecurity Duty” and Local Councils are authorised to issue a “Biosecurity Directive” to the owner or occupier of a property where weeds are sighted/reported.

Where a property owner/occupier is issued with a biosecurity directive (ie. weed notice), they have a legal obligation to control the weed in the manner described by the risk rating. Weeds declared as a biosecurity risk may cause harm to human health, the environment or agriculture.

Biosecurity Weeds are placed into the following categories:

Risk Rating 1 – Very High Risk – Prohibited Weeds

The plant must be eradicated from the land and the land must be kept free of the plant.

Risk Rating 2 – High Risk – Prohibited Weeds

The plant must be eradicated from the land and the land must be kept free of the plant.

Risk Rating 3 – Medium Risk – Controlled Weeds

The plant must be fully and continuously suppressed and destroyed.

Risk Rating 4 – Marginal Risk – Controlled Weeds

The growth of the plant must be managed in a manner that continuously inhibits the ability of the plant to spread and the plant must not be sold, propagated or knowingly distributed.

Risk Rating 5 – Low Risk – Restricted Plants

The growth of the plant must be managed in a manner that continuously inhibits the ability of the plant to spread and the plant must not be sold, propagated or knowingly distributed.
