Nonnative (also called exotic) plants and animals occur in a given area as a result of deliberate or accidental introduction by humans. Exotics are not natural components of the ecosystems and have not evolved with the species native to the area. Without predators and other environmental factors to control their numbers, they can easily get out of control and cause a variety of problems for native plants and animals.There are a number of exotic species in Biscayne National Park.
