The cue appears to be chemical rather than a biological organism, and may well be species-specific; the four species of native anurans that we tested were not influenced by toad larval cues.

The cue retains its effectiveness after being frozen, but not after being dried, or after 7 d in water. Pages in: W. Sutherland, L. Dicks, S.

Thank you for considering submitting additional evidence about this intervention. Ideally we would like all submitted evidence to have been published in peer-reviewed literature.

However, we do welcome evidence of any nature. Please be aware that given the volume of work we have we cannot guarantee a response to every submission. This score is based on the direction and size of the effects reported in each study. There is some variation between actions, e. The effectiveness score does not consider the quantity or quality of studies; a single, poorly designed study could generate a high effectiveness score. How certain can we be that the effectiveness score applies to all targets of the intervention e.

This score is based on the number, quality and coverage species, habitats, geographical locations of studies. Actions with high scores are supported by lots of well-designed studies with a broad coverage relative to the scope of the intervention.

However, the definition of "lots" and "well-designed" will vary between interventions and synopses depending on the breadth of the subject. The overall effectiveness category is determined using effectiveness, certainty and harms scores generated by a structured assessment process with multiple rounds of anonymous scoring and commenting a modified Delphi method.

In this assessment, independent subject experts listed for each synopsis interpret the summarized evidence using standardised instructions. What Works in Conservation provides expert assessments of the effectiveness of actions, based on summarised evidence, in synopses.

Subjects covered so far include amphibians, birds, mammals, forests, peatland and control of freshwater invasive species. Professor Shine hopes to involve community groups in the use of these new control methods. He says that although there has been a huge effort to slow the toad front by communities in Western Australia and the Northern Territory, the toad front is progressing as fast as ever. They're widely seen as a major problem. In community surveys they're identified by many people as the worst invasive species we have.

Previous methods for controlling cane toad numbers have included traps and fences but have mainly involved physically removing them from the environment, often by putting them in a plastic bag in the freezer. Very little of that has actually been devoted to try to understand what toads are doing.

Now that we've done that, it does seem that there are really encouraging avenues. He says the main impact of the toad invasion has been on large predators such as goannas, quolls, king brown snakes and death adders. Its dramatic, and that has all sorts of flow on effects.
