This study was carried out in Lake Karatas which is located at the site of Burdur Depression in the southwestern Anatolia (Tefenni Plain). The main aim of the study is to determine the changes of paleovegetation and the factors that effect these changes from similar to 2000 cal. BP years ago to Lake Karatas and its surroundings. For this purpose, fossil pollen analysis methods were applied on sediment core with a total length of 255 cm. The data obtained were diagrammed in the Tilia 2. 0. 41 program. Pinus sp., Juniperus sp. and Quercus sp. (evergreen) in arboreal pollen (AP) and Chenopodiaceae, Asteraceae, Lactuaceae and Poaceae in nonarboreal pollen (NAP) are important species that forming the vegetation. The temporal changes of these species reveal the local vegetation structure which is effective around the lake. Generally Abies sp., Cedrus libani and Quercus sp. (evergreen) indicate that 1460-1150 cal. BP, 840-680 cal. BP and 680-480 cal. BP are cold periods. In the whole diagram, the peak period of human impact was determined as 840-30 cal. BP. Olea europaea, Vitis sp. Fraxinus sp. in AP and Polygonum aviculare, Plantago lanceolata, Centaurea solstitialis in NAP corresponds to the peak period in the diagram. As a result, depending on the methods of analysis of fossil pollen, as a result of climate change and human impact, the variety of individual plant species constituting the paleovegetation structure and forest progression / regression were evaluated.
