OK, the following Observation Fields should map to the Alive or Dead annotation:
https://www.inaturalist.org/observation_fields/92
https://www.inaturalist.org/observation_fields/6541
https://www.inaturalist.org/observation_fields/6977
https://www.inaturalist.org/observation_fields/8046
https://www.inaturalist.org/observation_fields/160
https://www.inaturalist.org/observation_fields/9111
Certain values won’t affect the annotation, like Moribund for Dead or alive and No for Roadkill. The site is also auto annotating observations that currently have these fields, it might take a little while to go through all of them.
I’m sure we missed a few, so if there are any well-used fields that could work here, please let me know, especially ones that are not in English.
