What is the IUCN Red List designation for the species Sus scrofa globally?
Least Concern
On a global scale, the classification provided by the IUCN Red List for the entirety of the *Sus scrofa* species is 'Least Concern.' This high ranking is justified by the species' extraordinarily large overall population size and its extensive historical distribution, which spans across Eurasia and includes numerous introduced, established populations worldwide. However, this broad global assessment crucially obscures localized situations. While the species as a whole thrives, specific island subspecies, such as *S. s. riukiuanus*, face significant localized vulnerability due to factors like habitat loss. Furthermore, in many introduced regions, such as the southeastern United States, the feral populations derived from *S. scrofa* are categorized not as conserved species but as highly damaging invasive species requiring aggressive management and population reduction.
