What is the difference between invasive and introduced species?
An introduced species is a non native species that has one way or another been integrated into the native environment by human or other means. An invasive species on the other hand is an introduced organism that has become detrimental to the local environment.
What can we do about introduced species?
When these non-native plants and animals establish themselves in our local ecosystems, they outcompete and dislodge species that have evolved specifically to live there. The best way to fight invasive species is to prevent them from occurring in the first place.
What are species introduced by humans?
An introduced species (also known as an exotic species) is an organism that is not native to the place or area where it is considered introduced and instead has been accidentally or deliberately transported to the new location by human activity.

Are humans an introduced species?
Verdict: We’re not an invasive species, though we’re certainly doing harm to the world around us. If you think about it, all of the harm done by invasive species is by definition our collective faults; some kind of human action led to that species being in a new place where it then causes some harm.
How do humans introduce invasive species?
Invasive species are primarily spread by human activities, often unintentionally. People, and the goods we use, travel around the world very quickly, and they often carry uninvited species with them. Ships can carry aquatic organisms in their ballast water, while smaller boats may carry them on their propellers.
Are all introduced species invasive?
No, actually only a small percent of introduced species ever become invasive. However, it is nearly impossible to predict which species will become invasive and new species are being introduced every day. Some species are present for many years before they exhibit invasive characteristics.

When a new species is introduced, the species could potentially breed with members of native species, producing hybrids. The effect of the creating of hybrids can range from having little effect, a negative effect, to having devastating effects on native species.
What are some examples of introduced species?
