Bufo marinus were actively searched for and removed from Nonsuch Island (Madeiros, 2003 in Varnham, 2006).

The Japanese Environment Ministry is conducting research in an effort to exterminate the cane toads. Locals are being encouraged to cooperate with officials.
Kakadu National Park
Surveys of the toad population and a risk assessment have been conducted to try and determine the effect that the toads will have on the ecology of the area.
Chemical and mechanical control options used.
There is a proposal to eradicate cane toads and invasive mammals (rats, cats and dogs) from Viwa Island (60 ha), in Fiji to protect (among other native wildlife) the endangered Fijian ground frog (see Platymantis vitiana in IUCN Red List of Threatened species).
The removal of these invasive species from Viwa Island would benefit a range of other native species, including the banded iguana (Brachylophus fasciatus), Pacific boa (Candoia bibroni), and several species of gecko and skink. In addition to the biodiversity benefits, this project is expected to have several socio-economic benefits to the people on Viwa. These include an increased agricultural harvest, improved health and sanitation (domestic water supply and disposal), ecotourism and employment opportunities, and finally cultural pride for the Viwa Island people (104 people live on the island).
The University of the South Pacific is implementing this project with Joape Kuruyawa as the full-time project manager and funding by the Critical Ecosystems Partnership Fund (CEPF), the Australian Regional Natural Heritage Programme (RNHP) and the New Zealand International Aid & Development Agency (NZAID).

Résumé: The IUCN Red List of Threatened Species provides taxonomic, conservation status and distribution information on taxa that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those taxa that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable). The IUCN Red List also includes information on taxa that are categorized as Extinct or Extinct in the Wild; on taxa that cannot be evaluated because of insufficient information (i.e. are Data Deficient); and on taxa that are either close to meeting the threatened thresholds or that would be threatened were it not for an ongoing taxon-specific conservation programme (i.e. are Near Threatened).

Résumé: A study was conducted to determine whether simple morphological characteristics could be used to rapidly determine the sex of cane toads. We found that four characteristics reliably allowed rapid assessment of sex: skin texture on the dorsal surface, skin colour on the dorsal surface, the presence of a creamy-coloured stripe along the dorsal margin and the presence of vocal sac openings. These criteria were tested by an assessment of use by both experienced and novice operators and were shown to be reliable for sexing cane toads that were large enough to assess morphological characteristics reliably (individuals with a snout-vent length exceeding 50 mm). Of the four techniques, the presence of vocal sac openings proved to be the most reliable. Such techniques may be used for a number of purposes, and are particularly useful during conservation projects that attempt to eradicate or reduce the effects of this invasive alien species on local ecosystems.

16. Page, Amanda; Win Kirkpatrick and Marion Massam, July 2008, Cane Toad (Bufo marinus) risk assessments for Australia, Department of Agriculture and FoodWestern Australia.
Résumé: Models for assessing the risk that exotic vertebrates could establish in Australia have been developed for mammals, birds (Bomford 2003; Bomford 2006, 2008), reptiles and amphibians (Bomford 2006, 2008; Bomford et al. 2005). These Risk Assessment models have been further explored by Western Australia Department of Agriculture & Food (DAFWA) to confirm that they reasonably predict public safety, establishment and pest risks across a full range of exotic species and risk levels. Mammals and birds were assessed for the pest risk they pose if introduced to Australia, by calculating Vertebrate Pests Committee (VPC) Threat Categories. These categories incorporate risk of establishing populations in the wild, risk of causing public harm, and risk of becoming a pest (eg causing agricultural damage, competing with native fauna, etc). The 7-factor Australian Bird and Mammal Model was used for these assessments.
