This list of declared noxious weeds relates only to Gwydir and Inverell Shires. It is included as an example of the present New South Wales noxious weeds legislation. The main variation between this list and those for the other NIWAC councils are in the CC4 category.

Noxious Weeds Act 1993, Order #20 (Government Gazette 110 Aug 31 2006) and Order #22 (Government Gazette 34 February 28 2007 page 1148) specifies the following declared noxious weeds for Gwydir and Inverell Shires as from 1 March 2007:

Control measures Class 1:
The plant must be eradicated from the land and the land must be kept free of the plant.

The control objective for weed control class 1 is to prevent the introduction and establishment of those plants in NSW.

Section 8(3) of the Act specifies that Control Class 1 plants are notifiable. This means, inter alia, the presence of a Control Class 1 plant on the land must be notified to the local control authority (Council) within three (3) days of detection. A notifiable category also means the plant or plant material cannot be sold, propagated or knowingly distributed.

Control measures Class 2:
The plant must be eradicated from the land and the land must be kept free of the plant.

The control objective for weed control class 2 is to prevent the introduction and establishment of those plants in parts of New South Wales.

Section 8(3) of the Act specifies that Control Class 2 plants are notifiable. This means, inter alia, the presence of a Control Class 2 plant on the land must be notified to the local control authority (Council) within three (3) days of detection. A notifiable category also means the plant or plant material cannot be sold, propagated or knowingly distributed.

Common name	Scientific name	Control Class
Alligator weed	Alternanthera philoxeroides	2
Mesquite	Prosopis species	2
Parkinsonia	Parkinsonia aculeata	2
Salvinia	Salvinia molesta	2
Water hyacinth	Eichhornia crassipes	2

Control measures Class 3:
The plant must be fully and continuously suppressed and destroyed.

The control objective for weed control class 3 is to reduce the area and the impact of those plants in parts of NSW

Common name	Scientific name	Control Class
Giant Parramatta grass	Sporobolus indicus var. major	3
Green cestrum	Cestrum parqui	3
Serrated tussock	Nassella trichotoma	3* (cannot be sold)*
Silverleaf nightshade	Solanum elaeagnifolium	3
St John’s wort	Hypericum perforatum	3

Control measures Class 4:
The growth and spread of the plant must be controlled according to the measures specified in a management plan published by the local control authority.

The control objective for weed control class 4 is to minimise the negative impact of those plants on the economy, community or environment of NSW. Three separate management plans for CC4 weeds are specified for Gwydir and Inverell Shires viz. CC4A, CC4B, CC4C.

Control Class 4A

CC4A MANAGEMENT PLAN – Legal requirements within the Shires of Gwydir & Inverell
The growth and spread of the plant must be controlled by conducting an on-going and effective treatment program to reduce plant numbers and to minimise the plant’s negative impact on the land. Boundaries and waterways must be kept free of the plant to prevent spread from the property. All reasonable measures are to be taken to ensure vehicles, machinery and livestock moved off the property are free of the plant.

Common name	Scientific name	Control Class
African boxthorn	Lycium ferocissimum	4A
Golden dodder	Cuscuta campestris (Gwydir Shire only – see also CC5 listing)	4A
Nodding thistle	Carduus nutans	4A
Pampas grass	Cortaderia spp.	4A
Rhus tree	Toxicodendron succedaneum	4A
Paterson’s curse, Vipers/Italian bugloss	Echium spp.	4A
Sagittaria	Sagittaria platyphylla (asn Sagittaria graminea) (Gwydir Shire only – see also CC5 listing)	4A (Gwydir only
Sweet briar	Rosa rubiginosa	4A

Control class 4B
(As for CC4A plus plants cannot be sold, propagated or knowingly distributed.)

CC4B MANAGEMENT PLAN – Legal requirements within the Shires of Gwydir & Inverell
The growth and spread of the plant must be controlled by conducting an on-going and effective treatment program to reduce plant numbers and to minimise the plant’s negative impact on the land. Boundaries and waterways must be kept free of the plant to prevent spread from the property. All reasonable measures are to be taken to ensure vehicles, machinery and livestock moved off the property are free of the plant. Plant must not be sold, propagated or knowingly distributed.

Common name	Scientific name	Control Class
Blackberry	Rubus fruticosus (agg.spp.)	4B
Chilean needle grass	Nassella neesiana	4B
Harrisia cactus	Harrisia spp.	4B
Mother of millions	Bryophyllum spp.	4B

Control class 4C
(As for CC4A and CC4B plus provides for plants for which control by biological means may be an option.)

CC4C MANAGEMENT PLAN – Legal requirements within the Shires of Gwydir & Inverell
The growth and spread of the plant must be controlled by conducting an on-going and effective treatment program to reduce plant numbers and to minimise the plant’s negative impact on the land. Any biological control (#) or other control program directed by the local control authority must be implemented. Boundaries and waterways must be kept free of the plant to prevent spread from the property. All reasonable measures are to be taken to ensure vehicles, machinery and livestock moved off the property are free of the plant. Plant must not be sold, propagated or knowingly distributed.

Common name	Scientific name	Control Class
Prickly pear (includes rope, tiger, common, smooth tree & velvety tree pear – excludes Indian fig)	Cylindropuntia and Opuntia spp. except O. ficus indica (Indian fig)	4C

Circumstances where biological control may be an acceptable option?

(#) Any decision to implement a weed biological control program needs to be assessed on a property-to-property and/or area-to-area basis. Biological control is a slow, long-term control measure. It can be very effective in dealing with large infestations, particularly in inaccessible areas. But, it is generally NOT recommended for new, small or isolated infestations because biological control will not contain the problem. These types of infestations should be dealt with by conventional means ie manual removal, burn/bury or herbicide application.

It is also important to note that any biological control program requires manual assistance at certain times of the year to promote insect build-up and distribution. Details of how to gain optimum results from the use of biological control agents (cochineal and/or cactoblastis) are available on the North West Weeds website eg www.northwestweeds.nsw.gov.au/tiger_pear.htm

Control Class 4D:
The plant must be controlled where it impacts on normal agricultural practices including cropping and pasture management:

Common name	Scientific name	Control Class
Galvanised burr	Sclerolaena birchii	4D

Control measures Class 5:

The requirements in the Noxious Weeds Act 1993 for a notifiable weed must be complied with.
