Plants that are common to the temperate midlatitudes could also thrive in the tropics if they were grown at higher elevations. The effects of altitudinal zonation on plants and animals are unique to Latin America. Altitudinal zonation has had a strong influence on the types of native plants and animals found in the Andes and other mountainous regions. Only a few zones of the mountains may be used for some agricultural purpose. Altitudinal zonation makes it possible to grow many different types of crops.
