Many breeds, such as water buffalos, goats, chickens, Taoyuan pigs, Chinese geese and brown tsaiya ducks, were actually brought to Taiwan by early pioneers from the mainland, but the fact that they managed to adapt and make themselves at home here means that they qualify as native breeds, in contrast to outsider or improved strains.
