Those that remain that is. I'm in a region (inland tropics) that's only had toads for 20 years or so and there's been a substantial decline in a number of species that would logically be affected by eating them. Particularly goannas and pythons. The period also coincides with a decline in what used to be regarded as typical wet seasons, so it's hard to to be definitive... however there's no doubt that Eastern brown numbers have increased substantially over the same period (which presumably don't eat toads, but would've once competed with pythons for small marsupials, etc.). Only crows seem to have mastered the art of eating toads. Other birds, including chooks, appear to survive by avoiding them. I also run wide tyres on the car -- which has probably had about the same effect on the population as trapping. :) -- John H
