The results of multidisciplinary investigations (pollen, macrofossil, diatom, grain-size, lithological and radiocarbon analysis) concentrated on the upper reaches of the Ūla and Katra River basins were used to reconstruct the environmental history of the Late Glacial and Holocene. Lacustrine records go back as far as the Older Dryas and cover all chronozones of the Post-Glacial period. The earliest signs of the human impact and formation of forest openings may be related to the earliest forest clearings near settlements during the Boreal period. The agriculture was introduced into the area as late as in the second half of the Middle Neolithic. A continuous representation of agricultural indicators and a progressive opening of the woodland could be related to the increasing role of the farming economy during the Bronze Age. The formation of the open canopy, increasing soil erosion and changes in vegetation composition since (e.g.) 1800–1900 14C BP are the evidence of significant human impact on the environ...
