Özet
In the context of interpreting and planning today's environment, it is crucial to be aware of the characteristics of past periods. Lake sediments and the fossilized pollen they contain provide us with valuable information about past vegetation. This study discusses the paleovegetation records of sediment core of Lake Gâvur (Kahramanmaraş, Türkiye), which was dried in the 1970s. The area determined as the study site, Gâvur Lake and its vicinity, is of great importance for paleogeographic studies. In the region, there are ancient settlements dated back to the Neolithic period. Furthermore, excavations in the region are bringing to light well-preserved elephant fossils. A 5 m-long sediment core was obtained with an Eijkelkamp core sampler and palynological samples were taken at 10 cm intervals. The prepared samples were analyzed according to the standard method. The sediments were dated by AMS radiocarbon dating of bulk at two levels. Among arboreal pollen (AP) from approximately 4400 cal yr BP, the dominant arboreal taxa were Pinus, Cedrus, Quercus and Fraxinus. Initially, AP dominated NAP (non-arboreal pollen) along with the pollen diagram, and AP gradually decreased up to the present. The evaluation of the fossil pollen percentage indicates that in that period arboreal taxa were more widely distributed around the lake than they are in the present. Inferred major causes for the increase of pollen percentage of Poaceae and Asteraceae in the LG-3 (upper) zone of the pollen diagram are anthropogenic impacts.
