That would make sense as the last time I saw tads were when I was on the Manoa Falls Trail. The tads I noticed were in small pools that were off more on the pig trails rather than the highly traveled hiking path. The tads were still small, so at the time I didn't determine they were the local Auratus as I'm used to the local Cane Toad epidemic where I assume any tad is the baby of a Cane Toad.
Sorry to hijack your thread with a question, but I wonder how hard it would be to establish a new location of the invasive Auratus? I've got a few man made Japanese style outdoor ponds on my property and it would be neat to see some Auratus start up over there. I have a feeling that they would sadly become a snack to the Cane Toads I can't keep out of there.
