Preface

The Glossary of Wildland Fire Terminology provides an extensive listing of terms and definitions used by the National Wildfire Coordinating Group (NWCG) community. This document contains terms commonly used by NWCG in the areas of wildland fire and incident management and is not intended to list all terms used by NWCG members and users.

The NWCG has approved this glossary for use by the NWCG and its subgroups. The NWCG has directed that all NWCG glossaries will be based upon the Glossary of Wildland Fire Terminology for the purpose of maintaining definition consistency and clarity among documents.
