What is a naturalized organism?
A non-indigenous organism that is permanently established and is self-sustaining in a non-native area. Botanists use the term naturalized when referring to plants, whereas biological control workers typically refer to biological control agents as established once the agent has become a permanent member of an areas fauna. In an ecological sense, naturalized and established mean the same thing. Brazilian peppertree and melaleuca are two examples of the many naturalized plants in Florida.
