OK, a little experimentation with this yields some bad news…
I put up an observation and gave it an ID of “Quercus roburt” (deliberate mis-spelling to make it an obvious placeholder)
.json shows the species_guess as “Quercus roburt”
I add an ID of Quercus robur (valid taxa ID) and it shows the binomial and vernacular.
.json now shows species_guess as “Pedunculate oak” (the vernacular for Quercus robur)
I withdraw the Q. robur ID and the placeholder of “Pedunculate oak” is displayed.
.json continues to show species_guess as “Pedunculate oak”
No matter what ID I apply, it has it’s vernacular replace the placeholder, and there appears to be no way to find the original placeholder
No where in the .json is the “Quercus roburt” that I originally entered, so it is gone for good!
