How to manage weeds

Weed management handbook

The weed management handbook provides information on strategic and planned approaches to weed management, including integrated weed control methods.

Weed control option tables are included for 46 of the Northern Territory's (NT) most problematic weeds.

These list which herbicides are registered for use in the NT, ideal treatment times and which treatment methods should be used for best results.

The handbook also details important safety information relevant to use of herbicides.

You can either download the weed management handbook PDF (12.9 MB) or contact the Weed Management Branch for a hard copy.


Weed management planning

Weed plans help to identify and prioritise weed management requirements for an area.

There are different types of weed management plans that may provide useful information when developing a property, tenure or industry level weed management plan.

Property level plans help individual land managers to develop and implement on-ground control programs that address legal requirements and are as strategic as possible.

Property planning

If you have declared weeds on your property, you should have a weed plan to assess, control and monitor those weeds.

Use the below guides to help you develop your own property weed plan:

Catchment management planning

Catchment plans can be produced to inform weed control programs within surface water catchments or river systems.

These plans should involve all landholders within a catchment to get the best results.

If you have any questions, contact the Weed Management Branch.


Weed mapping and data sharing

The Weed Management Branch manages the Northern Territory (NT) weeds dataset which contains data about weeds in the NT.

Community access to this weed data allows better cooperation between neighbours and weed management planning.

It helps prevent weeds from spreading by informing weed locations and helps plan which weed types and locations should be targeted for control.

For advice and assistance, you should contact the Weed Management Branch:

  • before starting a weed mapping project
  • when you have data to submit
  • when you need weed data for special projects or research
  • to report alert weeds.

Find out more below.

NR Maps

You can access weed locations through the free web mapping application, NR Maps.

Digital data requests

The NT weed dataset can be downloaded for free. Licence terms apply.

If you're looking for digital data that is not available online, you need to complete a digital data request form.

You don't have to pay for data unless your request is more extensive or complicated than normal.

Read more about requests for environment data.

WeedMate app

You can use the NT WeedMate app to collect weed data points for general mapping purposes.

The app helps you:

  • collect information about the weed species, density and location
  • add extra information such as treatments, chemicals and growth stages
  • organise your data in a format ready for mapping.

To find out how to download and use the app, go to the Department of Environment, Parks and Water Security website.

Other ways to share data

Land managers can help manage the NT's weeds by submitting weed data direct to the Weed Management Branch.

Submitted data will be made available to the public on request.

To find out which organisations have contributed weed data, go to the Department of Environment, Parks and Water Security website.

For step-by-step instructions on how to collect weed data and process it for use in weed management, get the Weed data collection field guide PDF (4.4 MB).
