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.  :)
