Late Holocene environmental change and the record of human impact at Gravgaz near Sagalassos, Southwest Turkey

This paper presents the palaeoecological analysis of a sediment core extrac ted from the marsh of Gravgaz in the Pisidian Lake District (southwest Turk ey). The sediments are Late Holocene, dating back to c3300 BP. The research is part of an interdisciplinary project, aiming to reconstruct the palaeoe nvironment of the Sagalassos' territory, and to determine the impact of the former inhabitants of the area on the landscape. The Late Holocene pollen diagram shows four pollen assemblage zones: a phase with dominance of pine forest (zone A: c3300-3200 BP; Cal.-1630-1520 BC till - 1520-1430 BC), a de forestation phase (zone B: c3200-3300 BP; Cal. -1520-1430 BC till -210-240 BC) an important cultivation phase (zone C c2300-1300 BP, Cal. -210-240 BC till AD 660-770) and a final reforestation phase (zone D, from c1300 BP, Ca l -AD 660-770, till the present day). The results are complimented with arc haeological and sedimentological data.
