It’s first day of SP23 classes on Monday, so this key is hopefully going to be my side endeavor apart from teaching stuff:
https://forum.inaturalist.org/t/wiki-an-unknown-identifiers-tree-of-life-draft/38591
But that’s also a wiki so anyone else can step foot in there too, if they want to.
As it gets built out, there should be ways to get people’s field guides linked onto it at likely spots. So… great idea!
