Abstract. The database of forest wildfires that occurred in Central Siberia in the years 2006 and 2007 was created on the basis of satellite image analysis. The database allowed to construct an up-to-date map of fire hazards and depict the geographic distribution of forest and non-forest fires during fire season. The duration of the active burning phase for the majority (88%) of forests in the region was 1 day. The spatial-temporal distribution of forest fires indicates a maximum fire risk at the end of June and the beginning of July and in southern regions - also in spring and autumn. The analysis of images with depicting damage to forestland allows to state that c. 30–40% are the stands with different degree of damage of which less than c. 30% show weak signs of recovery.

Key words: forest wildfire, fire distribution, forest damage, fire hazard regions.
