This work explores the expansion of natural regeneration after the forest fire in the National Park Bohemian Switzerland, which occured in June 2006. Aerial photography were acquired in years 2009 and 2011 and both were used. The resulting accuracy achieved in the natural regeneration classification was 96 % in the year 2009 and 94 % in the year 2011. Natural regeneration covered 14% of the territory in year 2009 and in the year 2011 it was 51%. Furthermore comparison between the coverage of the natural regeneration and amount of individuals on the permanent research areas was made. The resulting correlation coefficient and coefficient of determination were low. The reason is, that the natural regeneration coverge detected using remote sensing is affected by dry crowns, high diversity of natural regeneration and also the absolute positional accuracy of aerial images.
