Caring for and Healing the Earth

Alien Plants

Alien Plants are those that are not native to a particular area. There is debate over what a "native" plant is. In North America it is usually taken to mean a plant that was growing here before the invasion of Europeans.

Alien plants may be invasive or non-invasive. The whole issue of alien plants is important because of those that are invasive. An invasive plant is one that "takes over" an area or ecosystem.
