Invasive Species Definition Clarification and Guidance

An invasive species is "an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health" as per Executive Order 13112: Section1. Definitions.

Invasive Species Definition Clarification and Guidance White Paper (2006)
National Invasive Species Council.
Submitted by the Definitions Subcommittee of the Invasive Species Advisory Committee (ISAC), approved by ISAC Apr 27, 2006.
The purpose of the Invasive Species Definition Clarification and Guidance white paper is to provide a non-regulatory policy interpretation of the term invasive species by identifying what is meant and, just as important, what is not meant by the term. The white paper also provides insight into those areas where societal judgments will be necessary to implement effective public policy. The utility of the clarification white paper is in education, conflict resolution, and efficiency in the planning, prevention, control/eradication, and management of invasive species.
