The study is based on pollen analysis and radiocarbon datings of the organogenic deposits filling a palaeomeander in the San river valley near Kopki, and on archaeological material. The pollen diagram shows the vegetational changes during the late Holocene from ca. 3800 years 14C BP till recent times. The phases of increasing settlement recorded in the diagram were connected with the younger periods of the Bronze Age, the period of Roman influence and the early Middle Ages up to the present times.
