This thesis researches forest history and human impact on it in prehistory and early Middle Ages by means of soil charcoal analysis, i.e. pedoanthracology. It focuses on a site called "Roztocký háj" with long-term human settlement near Roztoky u Prahy in central Bohemia. Pedoanthracology brings information about past woody vegetation that is very local and without much anthropogenic influence. On the other hand, archeoanthracology focuses on charcoal originating from archeological excavations directly from human settlements. These charcoals are therefore formed by human behaviour and provide general view on woody vegetation in wider surroundings of the site. Comparing results of these two approaches in Roztoky is allowed by long-term archeological excavations. They provided previously analyzed and partially published charcoal dataset. Newly obtained pedoanthracological dataset brings finer spatial scale, allows to find out the effect of local conditions on the charcoal spectra and also allows identification of possible purposefully selected taxa in the archeoanthracological assemblage. Another part of this work describes present-day vegetation around the soil profiles and examines it's possible continuity with the past vegetation. 4 soil profiles provided quite species-rich (17 taxa) charcoal...
