Abstract	A 7.5 m sediment core from Lake Bolata, a small former coastal liman lake in northeastern Bulgaria, was analyzed for pollen and plant macrofossil content in attempt to trace the changes in the vegetation, human impact and the influence of the Black Sea during the last ca. 6,000 years. Lake Bolata started its existence when the rising Black Sea level reached the elevation of the bottom of the depression. By that time nearly all tree species were already present in this area with the exception of Carpinus orientalis. The comparison of the arrival time of oriental hornbeam at different sites along the Bulgarian Black Sea confirmed the reliability of the local radiocarbon chronology. For the period under study the vegetation of the region around the site can be described as a forest-steppe due to NAP values higher than 40% of the pollen sum. Forests on the slopes of the river canyon consisted of Quercus spp., Acer, Carpinus orientalis, Fraxinus ornus, Fagus and possibly Tilia. Riverine forests formed stands composed of Salix, Alnus, Ulmus, Fraxinus, Carpinus betulus and Vitis as a liana. The vegetation on the Cape Kaliakra plateau, bordering the canyon, was dominated by diverse herbs and most of these could be considered xerophytes. The oldest occupation period belongs to the Eneolithic, documented by the occurrences of Triticum-type pollen at 5570–5170 cal b.p. (3620–3220 b.c.). The next period of higher continuous Cerealia-type values corresponds to 3450–1830 cal b.p. (1500 b.c.–a.d. 120). The macrofossil record chiefly provides evidence about plant communities of aquatics and helophytes.
