Why do non-native plants threaten native plants?

Destruction and replacement of ournative plants by invasive species has several significant consequences. Wildlife that depends on native plants is often unable to adapt and may be forced to leave the area or die out. Invasive aquatic plants can completely fill a water body, driving fish and wildlife from the area.

An invasive species can be any kind of living organism-an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism's seeds or eggs-that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health.
