Detailed explanation-1: -An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.

Detailed explanation-2: -Invasive species are animals or plants from another region of the world that don’t belong in their new environment. They can be introduced to an area by ship ballast water, accidental release, and most often, by people.

Detailed explanation-3: -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.

Detailed explanation-4: -Non-native species are organisms that do not occur naturally in an area, but are introduced as the result of deliberate or accidental human activities. Unlike invasive species, non-native species may not hinder or prevent the survival of others within the ecosystem.

Detailed explanation-5: -Invasive species can be introduced to an area by ship ballast water, firewood, accidental release, and by people. Human actions are the primary means of invasive species introductions. See our pathways information to learn more about how invasive species are introduced to new areas.
