When I was a child there was a cabin we'd visit often, and many year it had a population of toads as if it had been raining them (no exaggeration). It was hard to not step on them.

Not many years later, as young teenagers, a single toad was hard to spot. I recall a lot of frog catching days too, that are just not possible anymore. It doesnt take much to effect their populations severely, does it? Is chytrid fungus spread worldwide?
