Weed Management

Break O’Day Drought Weeds Project

Following the 2019 drought Break O’Day Council and four other drought-affected councils have been offered support from the Tasmanian Government’s Drought and Weed Management Program, part of the Tasmanian Weeds Action Fund.

The focus of the state Drought and Weed Management Program is to tackle weeds that get an advantage from drought conditions and reduce their impacts on agricultural production.  We are working with Biosecurity Tasmania and the four other councils to deliver a coordinated program in Break O’Day during 2020/21.

The Break O’Day Council Drought Weeds Project is providing $30,000 of grants funding for farmers and a Drought Weeds Officer to support Break O’Day farmers with their weed management and applications for project funding.  It will also develop community and industry weed management priorities for future work.

‘Drought Weeds’ can threaten agricultural productivity

  • through their growth and reproduction, including when drought breaks, to out-compete desirable species or be a danger to stock
  • as a result of farmers needing to prioritise drought relief actions for stock and production over weed control
  •  by being newly introduced by activities or conditions during or after drought.

Drought Weeds Grants for Farmers

Guidelines and Eligibility for the Drought Weeds Grants and an Application Form for the Break O’Day Council Drought Weeds Grants can be downloaded here.  The guidelines are common to the five participating Councils while the Application Form includes Break O’Day specific details.

Eligibility conditions apply but there is considerable flexibility for funding projects in the guidelines and additional conditions in the Break O’Day Drought Weeds Grants Application Form.  Joint or group applications are encouraged since weeds have no regard for property boundaries and to promote coordinated weed management.

Applications due Sunday 27 September 2020.

Further rounds may be offered if the Drought Weeds Grants are not fully subscribed.  Farmers and landholders are encouraged to also use the Break O’Day Drought Weeds Project to plan their weed management and future projects generally.  The Tasmanian Weed Action Fund will open its Round 2 grants program in 2020, with wider objectives.

Farmers and landholders interested in accessing this funding should contact the Break O’Day Drought Weeds Officer, Peter Heading, for support with their weed issues, planning solutions and making an application.

In 2016, Council made the decision to employ a Weed Program Co-ordinator after identifying weed management within the municipality was lacking structure and was considered a priority by the community. This position is dedicated to council owned or managed land only.

The Weed Program Co-ordinator, working within the scope of the BODC Weed Management Plan;

  • Develops an annual weed management program and implements this using a range of treatment methods.
  • Strategically prioritise areas for treatment based on location, natural and economic value, weed species, size of infestation and type of weeds present.
  • Organises and carries out identification of weed infestations including mapping and monitoring as well as areas that are weed free.
  • Controls record management of weed treatments and follow up actions. Engage with landowners and offering advice regarding weed management.

The council weed management program is developed yearly. It is broken down into areas and priorities within those areas and includes:

  • Mapping
  • Monitoring
  • Routine inspections
  • Treatment – specifically and non-specifically (e.g. public notification of infestations)
  • Target weeds – specific problem weeds in certain areas
  • Quarry management
  • Tip Management
  • Hygiene
  • Treatment follow up (when and how)

The program is a working document. This fluidity allows for flexible movement and ad-hoc activities to occur in the changing environment of the municipality. It allows the categorisation of infestations from eradication or containment and seasonality of individual weeds.

Priority weeds in Break O’Day include (from Break O’Day Weed Management Plan):

  • Gorse (Ulex europaeus)
  • Willow (Salix fragilis)
  • Pampas (Cortaderia species)
  • Brooms (Genista monspessulana, Cytisus multiflorus, C. scoparius)
  • Spanish heath (Erica lusitanica)
  • Boneseed (Chrysanthemoides monilifera)
  • Bridal creeper (Asparagus asparagoides)
  • Blackberry (Rubus fruticosus)
  • Any ‘environmental weed’that is deemed to be a high risk of spreading into valuable bushland and other native habitats

We need your help! If you notice a weed in your community we want to know!

If you are not sure whether it is a weed or not you can always check our priority weed list found here.

If you would like to report a weed, please send an email to admin@bodc.tas.gov.au with ‘Weeds’ in the subject line. To help us with our records and treatment plans it would be helpful to include the below information as well;

Name (optional)

Phone number (optional)

Date of observations

Type of weed (if known) or description

Photo (if you have one)

Area where the weed was found

Description of location

Any further information you would like to add?

Below are some of our problem weed species and some basic information on controlling them. These are by no means the only weeds to be concerned about in Break O’Day.  There are others, including species just as important because they are not known to occur here and that we don’t want.

Successful management of weeds requires careful planning, don’t rely on the basic information listed here.  A good place to find more and detailed information on weeds are the Invasive Species webpages of the Department of Primary Industries, Parks, Water and Environment.

The other things to remember are prevention: soil and water ‘hygiene’ and to be vigilant and respond early.  And follow-up: be persistent and diligent with a well planned control program over however many seasons it takes.

The are legal obligations for land owners and managers to not spread and to control weeds that are ‘declared’ in Tasmania under the Weed Management Act 1999.  ‘WONS’ are Weeds of National Significance which are Federal government priorities for management.  There are also ‘environmental weeds’ that pose a significant threat to our native flora and fauna by invading, displacing and degrading native habitats.  Many environmental weeds are not declared weeds, but most declared weeds and WONS are.

Spanish Heath

Erica lusitanica

Status – Declared Weed

Spread – Very small seed by wind, water – and by slashing. Stems can take root (layering).

Time of treatment – When actively growing and before flowering – March-June.  Avoid when flowers or seed are on plants.


Ulex europaeus

Status – Declared Weed

Spread – Seeds flung from pods and remain viable in soil for many years.

Treatment – Hand pull small plants; cut&paint stumps and spraying.  Mechanical clearing or other physical removal are useful controlling with large infestations.

Time of treatment – Chemical control when actively growing (spring to early summer and after autumn break). Avoid spraying when in flower and when bees are active.


Status – Lawn & pasture weed.
