Terms used in relation to aquatic systems

Terms used in relation to Environmental Legislation, Policy, Plans & Strategies

 

 

Information on this page is intended to assist people in developing a common understanding of the technical and scientific terms, abbreviations  and acronyms used in environmental reports, plans and strategies.

By increasing our common understanding we avoid confusion and misrepresentation of meaning.

The environmental glossary is a valuable aid to students and people involved with preparing reports and submissions.

The environmental glossary provides a recent history of terminology used  as well as opportunities for maintaining an awareness of new and emerging  language in conservation and environmental management.

SWIFFT welcomes additions or refinements to the glossary. Contact SWIFFT.
