Approximately 100 individual cane toads were imported to Australia in 1935. In 1936 and 1937 their offspring were dispersed at numerous locations on the Queensland, coast, and their range has rapidly expanded to the north and west and more slowly to the south. Our best present estimate of the total Australian population is approximately 2 X 108. Efforts to control cane toads were first initiated in the mid nineteen eighties, when it was realized that their expanding range would eventually cause them to occupy the Top End of the Northern Territory and potentially northern Western Australia, including many environmentally sensitive areas such as Kakadu National Park (Freeland 1985). One of the areas of focus of initial control efforts was comparisons of old, established and new, expanding populations of cane toads. This was done because many reports suggested that toad numbers were declining in areas where populations had long been established, suggesting that biological agents might exist in these areas that could be moved to cut populations at the front, reducing or stopping their spread (Freeland 1985). This impression was aided by the idea prevalent among the general public that nothing controls or preys on cane toads.
