Question
1. What was the problem with the sugar cane crop in the 1930's?
2. Where were the cane toads imported from?
3. Where do the toads lay their eggs? How many eggs can one female lay?
4. The toads eat everything, but why were they not effective against the cane grubs?
5. Why are cane toads so deadly to predators?
6. What WAS that guy smoking?
7. Name some things with which the cane toads have tried to mate.
8. Name some things the cane toads have tried to eat.
9. Give several reasons why the cane toads can be so disastrous for native species. In other words, what are the reasons why they are such successful invaders?
10. Describe what might happen to the ecosystem where the toads invade.
11. Identify and describe some of the different ways in which people perceive and treat invasive species, in relation to the rest of the environment. For example one person interviewed likens cane toads to an invading army, whereas another embraces them as simply another of “God’s creatures’. Another has a novel, if quite brutal method of controlling their numbers. Does one of these ways of understanding the relationship between people and different aspects of the environment seem more compelling to you? Why?

Explanation / Answer
1. The cane grub threatened the crop in 1930.
2. The cane toad was originally from South America and then was introduced to Hawaii. It was then imported from Hawaai and was introduced into north-eastern Australia around 1935 to control a major pest, the sugar cane beetle.
3. Cane toads lay their eggs in still or slow flowing water. A female cane toad can lay 40,000 eggs.
4. Because they ate everything besides the cane grubs and beetles and their lifestyle didn't sync with the beetles, beetles weren't eye-level
