Wildfires are exceeding problem for many European countries located in south parts of the European continent. In the recent years there is an increase of wildfires in central and north Europe, which led to the need of common fire fighting strategies and lessons learned to be exchanged among scientific communities in the affected countries. Such strategies and common policies were started to be developed as pilots in two European projects called “FirEUrisk” and “Fire-Res”. Both projects have as one of their major outcomes a map of European Fire Behaviour Fuel Models (FBFMs) which are developed with the same idea as the American FBFMs developed by Scott and Burgan in 2005. In the article is compared and calibrated the possibility of future use in Bulgaria of the two FBFM 100 meters resolution sets of fuel models published as results in the two EU funded projects. The test zone selected is located in south-east part of Bulgaria, covering the area of municipality of Elhovo near by the village of Razdel. The fire used for calibration purposes have been active in the period 10–14 August 2022 with final total burned area of 797 ha, where 560 ha were forest areas and 237 ha were grasslands and pastures. For the calibration work is used FlamMap run as FARSITE subtool obtaining fire behaviour spread simulation result.
