Cane Toads (Bufo marinus)

Cane Toad (Bufo marinus)

Cane toads were released in North Queensland in 1935 to help control beetles that were damaging sugar cane crops. But they quickly became pests, and later migrated rapidly poisoning native species.

Because cane toads aren’t native to Australia, there are no natural predators or diseases that could control them, or keep them in check. For many years, scientific researchers have explored ways to eradicate cane toads. More recently, scientists have determined that it may be more effective to increase our understanding of cane toads and how to minimise their impact on Australia’s ecosystems.

How is the Australian Government tackling this problem?

The Australian Government has allocated funding to address this challenge, through both the Australian Research Council, which has funded research into controlling the impacts of cane toads, and the National Landcare Programme.

Cane toad (Bufo marinus) threat abatement plan

In 2005, The biological effects, including lethal toxic ingestion, caused by Cane Toads (Bufo marinus) was listed as a key threatening process under the Environment Protection and Biodiversity Conservation Act 1999.

The Australian Government has published a threat abatement plan that sets out the research, management and other actions necessary to reduce the impact of cane toads and protect native species and ecosystems affected by cane toads.

  • Threat abatement plan for the biological effects, including lethal toxic ingestion, caused by Cane Toads
  • EPBC listed key threatening process - the biological effects, including lethal toxic ingestion, caused by Cane Toads

National Landcare Programme

The Australian Government’s National Landcare Programme will invest $1 billion over the next four years to help drive sustainable agriculture as well as supporting the protection, conservation and rehabilitation of Australia’s natural environment.

The National Landcare Programme merges previous funding initiatives into one simple programme that puts Landcare back at the centre of natural resource management.

Across Australia, the National Landcare Programme will support sustainable land management practices to deliver long-term benefits to our communities, our environment, our economy and our country.

Standard operating procedure for euthanasia of cane toads

This procedure manual outlines several methods for identifying, humanely killing and disposing of cane toads. It also identifies inappropriate methods of killing toads.

The recommendations in this document are based on the latest cane toad literature and the results of a recent trial by the NSW Department of Trade and Investment, Regional Infrastructure and Services and the University of Wollongong that examined the impact of various euthanasia techniques on cane toads. The department will review these euthanasia methods as new information becomes available.

Community groups helping to control cane toads

Around Australia several not-for-profit organisations have been established to help protect native species from cane toads.

These groups are involved in projects to remove cane toads, conduct research into their impacts, and help increase community awareness about cane toads and frogs. These organisations can be a source of useful information and generally welcome involvement from the local community.

The following community groups are dedicated to reducing the impact of cane toads in Australia:

  • Kimberley Toad Busters
  • FrogWatch, Northern Territory
  • Clarence Valley Conservation in Action Landcare Network

Keeping track of cane toads

ToadScan is a national website developed by the New South Wales Department of Primary Industries to help communities, local governments and pest controllers gather data on cane toads in order to support control programs.

On the website you can report sightings of cane toads, the damage cane toads are causing and control activities happening in your area.

Cane toads: a history

Cane toads were released in Queensland in 1935 to control beetles that damaged sugar cane crops. The toad had reportedly solved similar beetle problems in other countries, including Hawaii and Puerto Rico. But due to an absence of predators and natural diseases, the cane toad became a pest in Australia, migrating rapidly and impacting upon native species.

Cane toads now inhabit Queensland, New South Wales, the Northern Territory and Western Australia. Many years of scientific research have yielded no broad-scale way to eradicate toads. Much of today’s research instead focuses on how to reduce the impact of cane toads on native species and ecosystems.

Cane toad research: biological control and impact issues

Around Australia scientists are conducting research to better understand cane toads and the impact they have on native ecosystems.

We now know that managing the impacts of cane toads, rather than attempting to eradicate the species, may be a more effective long-term approach. For example, some scientists are examining whether it’s possible to change the way native species cope with cane toads.

Here is a list of scientific resources about on cane toads in Australia.

  • Journal of Applied Ecology - Conditioned taste aversion enhances the survival of an endangered predator imperilled by a toxic invader
  • Shine Lab, The University of Sydney - Cane toad research
  • Rick Shine - Cane Toads in Oz
  • Science of Cane Toad Invasion and Control - Proceedings of the Invasive Animals CRC/CSIRO/Qld NRM&W Cane Toad Workshop

Identifying cane toads and tadpoles

If you intend to dispose of cane toads it’s important you can tell the difference between cane toads and local native frogs so you don’t kill frogs by accident.

While adult cane toads are usually very large - around 9 to 15 centimetres (or 3.5 to 5 inches) long, smaller toads can easily be confused with native frogs.

Cane toads have a number of distinguishing features, including:

  • dry, warty skin that may be grey, yellowish, olive-brown or reddish-brown
  • a bony ridge from their eyes to their nose
  • leathery webbing between their back toes
  • no webbing between their front toes
  • large glands on each shoulder.

The following list of resources will help you tell the difference between toads and frogs.
