Since the earliest times man has used plants to create physical barriers: as protection against wild animals and enemies; for shelter of dwellings, gardens, crops and livestock against injurious winds; to hide unsightly buildings or features of the environment; to provide privacy and for many other uses. Whereas in early times indigenous plants were used, the great majority of barrier plants in use in South Africa today are exotic.
