While the IUCN mostly only assesses the global conservation status of species or subspecies, in some older cases it also assessed the risks to certain stocks and populations, in some cases these populations may be genetically distinct. In all, 119 stocks or subpopulations across 69 species had been assessed by the IUCN in 2006.IUCN Red List, search for only stocks and subpopulations If a local stock or population becomes extinct, the species as a whole has not become extinct, but extirpated from that local area.
