Edited for clarity: I suggest changing the bright pink introduced symbol to a purple (i) or (*), or something that people here think is better, because the red exclamation point implies that action is needed, or that there is some immediate threat.
I have a question about the “introduced” icon - does iNaturalist have the potential to cause harm when there is a pink exclamation point marking introduced species?
For me, the (!) symbol indicates danger, and the red urgency. In the past, when I was just learning about invasive species, I might have taken that as an invitation to pull a weed.
Maybe the “introduced” icon could be an (i) or an asterisk - yellow? then upgraded to invasive/noxious (!) if flagged. For instance, dandelions are no big deal… why would we tell that to someone trying to learn about plants by flagging with a danger symbol?
