Cassi’s response explains why this status is showing up for P. scouleri when it shouldn’t, so someone needs to edit / remove that status.
I am currently seeing threatened statuses under the “Status” tab at https://www.inaturalist.org/taxa/166953-Plagiobothrys-scouleri, so there is indication that they’re endangered. If you’re referring to the red bar that sometimes appears at the top of the taxon page, that only appears when there’s a global threatened status, or when a threatened status appears within scope of your default search place. My default search place is California and I see
but if I sign out I don’t see that, b/c there’s no reason to assume someone who isn’t specifically interested in California would care about California-specific statuses.
