Behave Fire Behavior Modeling System, Version 7

The Behave Fire Modeling System version 7 (Behave⁷ or B⁷) is a collection of models that describe wildland fire and the fire environment. Behave⁷ is flexible, producing tables, graphs, and diagrams of fire behavior (surface and crown fire rate of spread and flame length; fire growth; maximum spotting distance; probability of containment); and fire effects (scorch height and probability of mortality). It can be used for a variety of wildland fire management applications. The Behave⁷ software has been completely redesigned, with a new interface and streamlined code. It is compatible with the Windows, macOS and Linux Operating Systems. It is the successor to BehavePlus Fire Modeling System versions 1-6 (2001-2025) for Windows and the original BEHAVE fire behavior prediction and fuel modeling system (1984-2001) for DOS.

If you have issues while using Behave⁷, please read the information in the box to the right of the window, especially the Frequently Asked Questions (FAQs) or contact the IIA Help Desk, which is open 24-hours/day, 7 days/week.

The Behave Fire Modeling System version 7 (Behave⁷) has been approved for use by all federal land management agencies and should be available from your Software Center or wherever you obtain software.

• It can take time to get the most current version of Behave7 added to a Software Center, so your agency may not have the most recent version.
• If you work for another agency and have issues installing it on your computer, we can talk with the appropriate oversight group and try to get it approved for use. Please let us know who to contact, if possible.
