Traces of human impact reflected in the pollen diagram from Tarnowiec mire near Jas?o (Jas?o-Sanok depression), SE Poland

Abstract

The pollen diagram from Tarnowiec concentrates on human impact on vegetation, and is supported by the archaeological background. The earliest evidence of human activities dated at ca. 6500 B.P. was probably connected with the Neolithic Linearbandkeramik culture. Further periods of settlement are recorded at ca. 5200 B.P. and at 4800 B.P. The next very distinct period of intensification in human impact at ca. 4200-3800 B.P. was most certainly connected with the presence of the Corded Ware culture. The next period of settlement occurred during the late Bronze Age, in connection with the development of the Lusatian culture from ca. 3200 B.P. but is recorded only faintly in the pollen diagram. The next colonization phase at ca. 2600 B.P. is possibly the result of Scythian invasions. The widest expansion of human impact came during the period of Roman influence. After this, anthropogenic indicators decreased during the Migration period. The youngest part of the pollen diagram reveals an intensification of anthropogenic indicators connected with early Medieval settlement.
