Invasive Species

Invasive species, also called exotics, or alien species, are imported from other parts of the world and can cause ecological destruction.

Exotics arrive without their natural controls, such as insects, diseases, and competing species to keep them in check, and as a result may spread rapidly, crowding or choking out the existing ecosystems. Invasive plants are spread through vectors, such as transportation, soil, water, and wind.
