I guess I just don’t understand how captive, native amphibians can have pathogens that are bad, yet still be healthy and should not be release back from where they came from. Example: I have 14 toad tadpoles in hopes of having a few females to keep, then letting the others go (not for breeding purpose). I also have Cope’s Grays raised from tads last year, and 2 Fowler’s toads, raised from toadlets last year. So releasing any of these would be bad for the population?
