Is there a way of specifying/categorizing that an organism belongs to a particular life-history, within a taxonomic unit.
Specifically, I am wondering about the distinction between sea-run Atlantic salmon (listed as endangered under the US Endangered Species Act) and land-locked salmon (a different life-history of the same species with no protected status).
At one point, land-locked salmon were considered a subspecies (Salmo salar sebago), but apparently it is really a life-history difference, not a taxonomic one.
It is misleading when iNaturalist obscures the location of observations of land-locked salmon and flags them as endangered.
Are there other taxa where it would make sense to be able to categorize life-histories within a species, and is there a feature (other than creating an observation field) that would allow this?
