FBAT Publications and Media
This page provides access to Fire Behavior Assessment Team (FBAT) reports which document the data collected and observations made while FBAT was onsite for a given wildfire incident. FBAT reports are generally 20 to 50 page long documents which present a range of information, including but not limited to vegetation/fuels, weather, suppression activity, fire behavior observations and measurements, fire effects, along with a description of the methods used. These reports are assembled quickly, with analysis and narrative mostly completed onsite, before departing an incident.
