The Glossary of Wildland Fire Terminology provides a comprehensive 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 fire use and is not intended to list all terms used by NWCG members and users. To ensure the information contained within the glossary is current and meeting user needs, a thorough review, covering a two-year period, was undertaken. Participants in this review included all NWCG Working Teams and the National Interagency Coordination Center. Through the efforts of the NWCG Information Resources Management Program Management Office, the glossary entries are now presented in a standard format, allowing for improved definition cross-referencing and access. This glossary is available electronically. In this format, information contained will be current when the glossary is accessed. The NWCG has approved this glossary for use by the NWCG and its Working Teams. The NWCG has directed that all NWCG document glossaries will be based upon the Glossary of Wildland Fire Terminology for the purpose of maintaining definition consistency and clarity among documents.
