An invasive (exotic, alien or introduced) species is any species of organism (plant, animal, fungus, etc) that is introduced into an area outside of where it occurs naturally and as a result it becomes damaging to the new ecosystem. Most invasive species can grow out of control when they are introduced to an area because there are fewer predators to keep the population controlled. This excessive growth of invasive populations can use resources and nutrients that are required for native species, and it becomes more difficult for native species to compete. Invasive plants can take over other vegetation by blocking out sunlight or using up vital nutrients. In many forests of the U.S, a vine called kudzu can grow about 2 feet a day. It climbs over trees and eventually blocks out all sunlight and reduces the ability of the tree to make food. Through this process, kudzu can kill hundreds of acres of forest.
