Festuco-Pinetum is an association of open forest dominated by Pinus sylvestris and characterized by the common occurrence of boreo-continental, peri-alpine and drought-adapted continental species, including species of dry grasslands. In the Czech Republic it occurs mainly on marl or calcareous sandstone in northern Bohemia, but it can also rarely be found on other types of calcareous bedrock. Similar, basiphilous, species-rich pine forests occur on scattered sites in other regions of the Bohemian Massif. Some of the current pine forest stands may have developed from deciduous forests due to grazing and other human influences, while others may be natural vegetation maintained by recurrent wildfires.
