Biological control of the cane toad in Australia: a review
The marine toad Bufo marinus is native to northern South America, parts of Central America and Southern Texas. It was deliberately introduced into Australia’s tropical north-east in 1935 in an unsuccessful attempt to control the cane beetle, a damaging insect pest of sugarcane crops. The toads quickly established in the new environment and began to [...]

Comparisons through time and space suggest rapid evolution of dispersal behaviour in an invasive species
During a biological invasion, we expect that the expanding front will increasingly become dominated by individuals with better dispersal abilities. Over many generations, selection at the invasion front thus will favour traits that increase dispersal rates. As a result of this process, cane toads (Bufo marinus) are now spreading through tropical Australia about 5-fold faster [...]

Draft Cane Toad Strategy for Western Australia 2009-19
The draft strategy outlines a 10-year management plan for cane toads and aims to provide an integrated response across the whole community to reduce the impact of the invasive species on biodiversity, social and economic values. Other general information on cane toads is also available at the WA DEC website.

Cane Toads!! Just hearing those words creates fear and loathing in many Australians. These feral amphibians have become a major invasive threat to Australian biodiversity since their introduction in North Queensland. Reports that these poisonous amphibians have invaded the Northern Territory and are heading for Western Australia fuel this national sense of fear and loathing. [...]

Mid North Coast Region Pest Management Strategy 2008-2011
The development of Regional Pest Management Strategies (RPMS) provides NPWS with a strategic approach to pest management across NSW. The Strategy developed for each region provides a tool to broadly identify pest distribution and their associated impacts across the park system. It details priorities for each Region, including actions listed in the PAS and TAPs. [...]

Australian tadpoles do not avoid chemical cues from invasive cane toads (Bufo marinus)
If invasive species are phylogenetically distinct from native taxa, divergence in intraspecific communication systems may allow control via methods that invoke behavioural responses by the invasives but not by local species. Previous work has exploited sexual signals in this respect (e.g. species-specific mate-attraction pheromones) but there is equal potential to exploit non-sexual signals, such as [...]

Do invasive cane toads (Chaunus marinus) compete with Australian frogs (Cyclorana australis)?
Despite widespread concern about the ecological impacts of invasive species, mechanisms of impact remain poorly understood. Cane toads (Chaunus [Bufo] marinus) were introduced to Queensland in 1935, and have now spread across much of tropical Australia. One plausible impact of toad invasion concerns competition between toads and native frogs, but there has been no previous [...]

Optimisation of handling, activation and assessment procedures for Bufo marinus spermatozoa
In the present study, we investigated handling, activation and assessment procedures for cane toad (Bufo marinus) spermatozoa. Optimisation of these techniques will facilitate the maintenance of sperm viability during cryopreservation and during in vitro fertilisation (IVF) techniques in reproduction technologies for endangered species. Spermatozoa were taken from testicular macerates and assessed using plasma membrane integrity [...]

Breeding-site selection by cane toads (Bufo marinus) and native frogs in northern New South Wales, Australia
Previous research on cane toads (Bufo marinus) has documented non-random selection of breeding sites by this invasive species. In the wet?dry tropics of the Northern Territory, toads selected spawning sites in open areas with gently sloping banks and shallow water. If consistent, such biases may present opportunities for toad control via waterbody manipulation ? but [...]

A Review of the Impact and Control of Cane Toads in Australia with Recommendations for Future Research and Management Approaches
The National Cane Toad Taskforce was formed in September 2004 as a subcommittee of the Vertebrate Pests Committee. This resulted from a request from the Northern Territory Minister for the Environment to the Natural Resource Management Ministerial Council (NRMMC) that a national task force be set up to coordinate a response to the threat from [...]

Cane toad
The cane toad (Bufo marinus) is not a declared pest in Queensland so there is no legal requirement to control them. Their original introduction in 1935 was to control agricultural pests, but they proved ineffective. For the past 60 years, cane toads have been expanding their territory in Australia, and are capable of colonising at [...]

The short-term effect of cane toads (Bufo marinus) on native fauna in the Gulf Country of the Northern Territory
The range of the cane toad has expanded rapidly in the Northern Territory, and there is growing concern that the species may have a detrimental effect on the native fauna. The aim of this study, therefore, was to determine the short-term effects of cane toads on populations of native fauna and, specifically, to compare the [...]

A comparison of cane toad and native tadpoles as predators of native anuran eggs, hatchlings and larvae
Few quantitative data exist regarding the impact of the introduced cane toad, Bufo marinus, on native Australian fauna. This study investigated predation by tadpoles of B. marinus and two native anurans (Limnodynastes ornatus and Litoria rubella) on eggs, hatchlings and larvae of native anurans that co-occur with these tadpoles in temporary and semi-permanent water bodies [...]

The Cane Toad (Bufo marinus)
The cane toad (Bufo marinus) in not a declared pest in Queensland so there is no legal requirement to control them. As the toads geographical range continues to expand however, concern has increased about their detrimental environmental effects, particularly on the wetlands of the Northern Territory. Studies into the feasibility of biological control have commenced.
