Weed mapping and data sharing

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

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


Weed data helps land managers plan which weed types and location should be targeted for control.

Weed data helps prevent weed spread by informing developers, exploration teams, utility providers and land users of weed locations before on-ground works.

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.

Contact the Weed Management Branch.

NR Maps

Weed locations are available through Natural Resource Maps, a free web mapping application.

Digital data requests

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

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

For more information on the full weed dataset and digital data request forms, go to environmental data requests.

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

Use the WeedMate app

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

The app helps you do all of the following:

  • 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 and Natural Resources website.

Other ways to share data

Land managers can help to 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 Environment and Natural Resources website.

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

Section 1 of the NT weed data collection manual PDF (2.7 MB) provides detailed information for data managers, researchers and land management agencies.

Section 2 of the NT weed data collection manual PDF (1.6 MB) provides detailed data definitions and weed lists for use by data managers.
