Some types of "native flora" actually have been introduced centuries ago by people migrating from one region or continent to another, and become an integral part of the native, or natural flora of the place to which they were introduced.
Algunhas clases de flora nativa, en realidade foron introducidas fai séculos, por exemplo, por emigrantes que viaxaron dunha rexión ou continente a outro, e co paso do tempo convertéronse en parte da flora nativa ou natural do novo hábitat.
