The Regional Pest Management Strategy 2005 lists 4 different groupings of plant pests associated with different control regimes.  They are:

• Total Control plant pests
• Progressive Control plant pests
• Containment Control plant pests
• Surveillance plant pests

4.1.2 Affected Parties and the Necessity to Act

In accordance with Section 6(1) of the Act, land includes, for the purposes of this Strategy, all or any of the portions of road bounded by:

The boundary of that land abutting that road; and
Lines extended from the end of that portion of boundary to the middle line of the road; and
The middle line of the road connecting those extended lines.

Total Control Plant Pests

Plant Pests:

African Love Grass (Eragrostis curvula)
Baccharis (Baccharis halimifolia)
Bur Daisy (Calotis lappulacea)
Coltsfoot (Tussilago farfara)
Entire Marshwort (Nymphoides geminata)

Strategy Rule for Total Control Plant Pests

Rule 4.1:

Land occupiers and other persons shall not sell, propagate or distribute any Total Control Plant Pests.

A breach of this rule creates an offence under Section 154(r) of the Biosecurity Act 1993.

Technical Method The Regional Council will carry out control operations to eradicate Total Control Plant Pests prior to seeding in an efficient and cost effective manner. Appropriate physical or chemical means will be utilised.

Progressive Control Plant Pests

Plant Pests:

• Nassella Tussock (Stipa trichotoma)

Strategy Rules for Progressive Control Plant Pests

In relation to the following rules, land occupiers must also comply with these rules on any adjoining roads as described in Section 6 of this Strategy.
Nasella Tussock

(a) Land occupiers shall, on all the land they occupy, complete a control programme to prevent nassella tussock plants from seeding by:

• 31 October every year within the area delineated on Map 1 contained in Appendix 3; or
• 30 September each year in all other parts of the Canterbury region.

(b) Land occupiers and other persons shall not sell, propagate or distribute any nassella tussock plant or part thereof.
A breach of any of these rules creates an offence under Section 154(r) of the Biosecurity Act 1993 and may initiate the regulatory procedures set out in Chapter 12. An exemption to any of the above rules may be soughtby any person in accordance with the procedures set out in Chapter 12 of the Strategy.

Containment Control Plant Pests

Plant Pests:

• Broom (Cytisus scoparius, C. multiflorus, Teline monspessulana)
• Gorse (Ulex europaeus)
• Nodding Thistle (Carduus nutans)
• Ragwort (Senecio jacobaea)
• Variegated Thistle (Silybum marianum)

Strategy Rules for Containment Control Plant Pests

In relation to the following rules, land occupiers must also comply with these rules on any adjoining roads as described in Section 4 of this Strategy.

Broom

(a)  Land occupiers shall eliminate broom infestations that cover up to 50 square metres in area and are greater than five metres from other broom infestations exceeding 50 square metres in area on the land that they occupy. For the purpose of this rule, eliminate means the permanent preclusion of the broom plant’s ability to set viable seed.

(b) Land occupiers shall eliminate broom infestations on the land that they occupy within 10 metres of any adjoining property occupied by another land occupier where that adjoining property is clear of, or being cleared of, broom infestations within 10 metres of the boundary between the properties. For the purpose of this rule eliminate means the permanent preclusion of the broom plant’s ability to set viable seed.

(c) Land occupiers and other persons shall not sell, propagate or distribute any broom
plant or part thereof. A breach of any of these rules creates an offence under Section 154(r) of the Biosecurity Act
1993 and may initiate the regulatory procedures set out in Chapter 12. Land occupiers are exempted from the provisions of these rules for the following:

• the requirement to eliminate broom when present as a hedge within a property; and
• the requirement to eliminate broom when present as a hedge on a boundary provided that the top and sides of the hedge are trimmed each year after flowering but before seed set to minimise seeding.

Land occupiers may apply for an exemption from any of the above rules in accordance with the procedures set out in Chapter 12.

Gorse

(a)  Land occupiers shall eliminate gorse infestations that cover up to 50 square metres in area and are greater than five metres from other gorse infestations exceeding 50 square metres in area on the land that they occupy. For the purpose of this rule eliminate means the permanent preclusion of the gorse plant’s ability to set viable seed.

(b) Land occupiers shall eliminate gorse infestations on the land that they occupy within 10 metres of any adjoining property occupied by another land occupier where that adjoining property is clear of, or being cleared of, gorse infestations within 10 metres of the boundary between the properties. For the purpose of this rule eliminate means the permanent preclusion of the gorse plant’s ability to set viable seed.

(c) Land occupiers and other persons shall not sell, propagate or distribute any gorse
plant or part thereof. A breach of any of these rules creates an offence under Section 154(r) of the Biosecurity Act
1993 and may initiate the regulatory procedures set out in Chapter 12. Land occupiers are exempted from the provisions of this rule for the following:

• the requirement to eliminate gorse when present as a hedge within a property; and
• the requirement to eliminate gorse when present as a hedge on a boundary provided that the top and sides of the hedge are trimmed each year after flowering but before seed set to minimise seeding.

Land occupiers may apply for an exemption from any of the above rules in accordance with the procedures set out in Chapter 12.

Nodding Thistle

(a) Land occupiers shall eliminate nodding thistle infestations:

• on the land that they occupy within 40 metres of any irrigation race or stockwater race; and
• on the land that they occupy within 40 metres of any adjoining property occupied by another land occupier where that adjoining property is clear of, or being cleared of, nodding thistle within 40 metres of the boundary between the properties.

For the purpose of this rule eliminate means the permanent preclusion of the nodding thistle plant’s ability to set viable seed.

(b) Land occupiers and other persons shall not sell, propagate or distribute any nodding thistle plant or part thereof.

• on the land that they occupy within 40 metres of any irrigation race or stockwater race; and
• on the land that they occupy within 40 metres of any adjoining property occupied by another land occupier where that adjoining property is clear of, or being cleared of, ragwort within 40 metres of the boundary between the properties.

For the purpose of this rule eliminate means the permanent preclusion of the ragwort plant’s ability to set viable seed.

(b) Land occupiers and other persons shall not sell, propagate or distribute any ragwort plant or part thereof. A breach of these rules creates an offence under Section 154(r) of the Biosecurity Act 1993 and may initiate the regulatory procedures set out in Chapter 12.
