In the sediment of the Blatuša peatland, 76 pollen and 124 non-pollen palynomorphs (42 ecologically indicative) were found. Based on the accumulated regional palynological taxa, the following zones were identified: Pinus - Fagus - (Ulmus) (Zone 1, depth 175 - 210 cm, period from ~ 2450 to 1650 BC), Fagus - Alnus (Zone 2, depth 85 - 175 cm, period from ~ 1650 BC to ~ 450 AD), Poaceae - Fagus - (Quercus) (Zone 3a, depth 45 - 85 cm, period from ~ 450 - 1300 AD) and Poaceae - Carpinus (Quercus - Fagus) (Zone 3b, depth 5 - 45 cm, period from 1300 to 1935 AD). The composition of the local palynological taxa and the ecologically indicative non- pollen palynomorphs indicates the dynamics of the hydrological regime as well as the trophic conditions on the habitat, with occasional domination of species from the family Cyperaceae, ferns Polypodiales or peat moss - Sphagnum. During the Zone 1 and 3b, the researched area was a mosaic of wetland vegetation and wet meadows, with partially developed peatland vegetation. Zone 2 is characterized by the relative local domination of the ferns, and Zone 3a by the relative dominance of the peat moss. The shares of arboreal pollen, anthropogenic indicators, charcoal particles and palynological richness point to the different intensity of anthropogenic pressure, which is mostly pronounced in the period from the developed Middle Ages to the present. Charcoal particles are evidence of regional and local fires as essential factors in succession processes. The quantity and quality of the analysed palynomorphs enable us to apply the results of the reconstruction of Holocene postglacial vegetation changes for the same period for a narrower area of central Croatia.
