Invasive species

Invasive Species 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.

Invasive vs Non-Native A non-native species is one which does not naturally occur in an environment. Not all non-native species are invasive, even if they displace native organisms. For example. most food crops are not native to where they are grown. Without human oversight, most of these species would not expand into new territory and threaten the ecosystem. Similarly, some non-native plants grown in gardens are invasive, while others are not.
