The captive/cultivated standard(s) is(are) a function of standards employed by iNaturalist’s partner bodies internationally.They make no sense but they make no sense consistently across institutional lines. To change the iNat standard would require changing standards elsewhere that have been around for a long time. Not going to happen.
It’s kind of like imperial versus metric. Metric is easier to learn and apply in every way but school kids in a surprising number of countries are still tormented with learning how to convert square inches to square yards because cultural intertia is what it is. I’ve lived in a country that is nominally metric for the great majority of my life but I remain saddled with the useless knowledge that there are 63,360 inches in a mile, just as I am stuck knowing that on iNat (and other such places) the same zebra can be wild or captive depending on which side of an arbitrarily placed fence it happens to be standing and a birch tree that longs for the forest in which it germinated is still laughably considered wild when the forest has been razed and the tree is left behind as a sad vestige placed dead centre in a suburban lawn. Hobgoblins of little minds and all that. Definitely not worth wasting time or bandwidth on.
