The full guidelines on this are here:
- should only be added if you can ensure all child taxa can be placed
- “Properly curated nodes on iNaturalist should have all of their children grafted beneath them”
- “As a rule of thumb, not including additional nodes in iNaturalist is preferable to including but only partially curating additional nodes as in the middle tree above. Please consider before introducing additional nodes: (1) are there global references that will enable curators to properly determine whether other taxa are siblings or descendants of the node? (2) are you willing to take the time to fully curate these other taxa? If during your curation you encounter partially curated nodes, it may be preferable to remove them rather than to fully curate around them if it is not possible or practical to fully curate them.”
While the guidelines above seem quite clearly written, it does not take into consideration the sheer number of these that are added by users. Many of the references the site defers to do not include these levels which make finding viable sources difficult and time consuming.
However, deactivating them will anger users.
