One thing I put in at the time I did the pond was a “hidden in plain sight” toad shelter. In fact, it blends in so well that I sort of forgot about it until the egg discovery a few days ago even though I step on it every day.
Everything I have read about “toad habitat” enhancements suggests installing shade providing/ partially enclosed structure with loose, sandy soil as a floor. The toads crawl in before dawn and bury themselves in the cool sand for a long rest until the next night’s predatory romp.
One structure I put together is comprised of a very large flat stone resting on brick pillars buried at ground level. Three sides have entrances/exits, two face open area and one is an alternate “escape” route into the ferns of the bog garden.
The “secret” Flintstones style toad abode and its northern facing entrance:
And the same @ the east entrance:
So is it being used? It didn’t dawn on me to look until the eggs appeared.
I do believe the answer is “yes”; something has been in and out and stirred around in the sand floor enough to leave some evidence in the doorway:
I realize that this is what is supposed to happen and that it what I hoped would happen, but I’m still amazed when it happens.
Now if the bats would only humor me a little and move in to their super-structure for at least a little while……
