                        Blackberry (Rubus fruticosus aggregate)

DESCRIPTION OF NOXIOUS WEED

Blackberry is a Weed of National Significance and is regarded as one of Australia’s worst weeds due to
its invasiveness, potential for spread, and economic and environmental impacts. Blackberry infestations
can reduce pasture production, restrict access to water and land, and provide food and shelter for pest
animals such as rabbits and foxes. Blackberry is a perennial, semi-deciduous shrub with prickly stems
(canes) that take root where they touch the ground, often forming thickets up to several metres high. It
varies from sprawling to almost erect.

The stems, which grow up to 7 m long, may be green, purplish or red, and are generally thorny and
moderately hairy. Young canes emerge from buds on the woody root crown each spring and grow very
rapidly (50–80 mm a day). Leaves are usually dark green on top with a lighter green underside. The leaf
veins and stalks are covered with short prickles. Clusters of flowers are white or pink. The berries change
colour from green to red to black as they ripen. The plant is semi-deciduous and sheds its leaves in
winter.

PURPOSE OF THIS PLAN

The purpose of this management plan is to outline the legal requirements for the control of Blackberry by
occupiers of land in the Cobar local government area (Cobar LGA).

In the Cobar LGA, Blackberry is a Class 4 noxious weed declared under Section 7, Order 20 of the
Noxious Weeds Act 1993 (the Act). All occupiers of land within the Cobar LGA must control Blackberry
according to this Management Plan No: BB-09/14.

CONTROL - OBJECTIVES & METHODS

To comply with the Act, Blackberry must be managed in such a way as to ‘minimise the negative impact
of the weed on the economy, community or the environment of NSW’. Occupiers of land are obligated to,
and must actively control Blackberry to prevent it from spreading, and its numbers and distribution must
be reduced by legal means.

The growth and spread of the plant must be controlled according to the following specified control
measures. Occupiers of land in the Cobar LGA may use all or any combination of the control measures
below.

   1. Chemical - effective treatment with a herbicide registered for Blackberry, in the manner specified
      on the product label. Best time to spray Blackberry is during the flowering - fruiting period. Do not
      apply herbicides to stressed plants. Conditions such as drought or severe low or high
      temperatures can decrease the effectiveness of herbicide action. As a guide, look at the tips of
      the canes. In times of active growth (the best time to spray) these will be producing fresh new
      leaves, and any new growth should be healthy, not wilted.

   2. Mechanical - if possible, physically remove the entire crown and root material of Blackberry. In
      dense infestations mechanised weeding with large earthmoving equipment may sometimes be
      necessary. Remove plants and surface soil with a bulldozer (‘scalping’) to ensure crowns and
      most of the roots are dug out. Afterwards, rake roots and leave them to dry out in the sun or
      collect them in piles for burning. Regrowth from crowns, root fragments and seed is inevitable, so
      follow-up treatment and site rehabilitation is essential.
General information on control methods for this weed can be found in the most recent edition of the
Noxious and Environmental Weed Control Handbook, published by the NSW Department of Industry &
Investment (www.industry.nsw.gov.au).

Cobar Shire Council (CSC) Weeds officers will inspect land within the Cobar LGA for infestations of
Blackberry. Education material will be made available and distributed during liaison with occupiers of
land.

CSC will undertake control work with allocated funds on land occupied by CSC and on certain roads and
watercourses, rivers or inland waters as provided by the Act.

SECTION 12 OBLIGATIONS (under the Noxious Weeds Act 1993)

An occupier (other than a public authority or a local control authority) of land to which a weed control
order applies must control noxious weeds on the land as required under the order.

If an occupier fails to comply with obligations under a weed control order, those obligations may be
enforced against the owner of the land as well as the occupier by a weed control notice issued under
Section 18 of the Act.
