In which region have population re-establishments from escapes been reported since the 1990s?
Answer
Great Britain.
The inherent adaptability of *Sus scrofa* means that escapes from managed populations frequently lead to the establishment of self-sustaining feral populations across diverse geographies. While the feral hog problem in the Americas is long-standing, subsequent escapes have caused similar re-establishment issues elsewhere. Specifically, reports confirm that population re-establishments resulting from escapes have occurred in Great Britain starting from the 1990s. This phenomenon is part of the broader global concern regarding feral pigs, which, due to their tapping into ancient, flexible genomes, can quickly maximize traits beneficial for survival in the wild.
