NWCG Glossary of Wildland Fire, PMS 205

The NWCG Glossary of Wildland Fire provides an extensive listing of approved terms and definitions used by the NWCG community. It 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 groups and member agencies. The NWCG has directed that all committee and subgroup product glossaries be contained within the NWCG Glossary of Wildland Fire to maintain definition consistency and clarity among documents.

Within this guide, users and committees can find instructions on the glossary process; tips for viewing the glossary on the NWCG website; guidance for committees and subcommittees assigned ownership of glossary terms, including how to request, develop, and revise a glossary entry; technical requirements for complete glossary entries; and a list of contacts for support.

The NWCG User Guide for Glossary of Wildland Fire is developed and maintained by the Data Standards and Terminology Board (DSTB), under the direction of the Data Management Committee (DMC), an entity of the National Wildfire Coordinating Group (NWCG).

Prior to 2021, this information was contained in the NWCG User Guide for Glossary of Wildland Fire, PMS 937. While they may contain current or useful information, previous editions are obsolete. The user of this information is responsible for confirming that they have the most up-to-date version. NWCG is the sole source for the publication.

Comments, questions, and recommendations shall be submitted to the appropriate agency program manager assigned to the DSTB. View the complete roster.
