Glossary of the Main Technical Terms Used in the Handbook

Throughout the Handbook a variety of terms have been used to describe the origin and status of alien species, their residency, the invasibility of ecosystems and the pathways of introduction. We have attempted to use these terms consistently in the Handbook and provide a glossary of definitions. The meaning of these technical terms is based on previously published terminology and reflects how particular categories were understood during the production of the Handbook. It should be made clear that we do not propose a new set of definitions; rather we hope to achieve a broad consensus among different subdisciplines of invasion biologists. Further details of terminology, including additional terms, can be found in the reference list at the end of the glossary.
