The pollen analysis of the chosen Quaternary localities (Stříbrná bystřina, Rýchory) from the Giant mountains
The paleobotanical reconstruction of the vegetation development of the Giant Mountains is based on the pollen analysis of sediment of moors. The peat has risen and accumulated the pollen grains and spores from the Late Glacial during the Holocene. The peat profiles studied were taken from two localities (Stříbrná bystřina, Rýchory) differing in vegetation types and topography. The investigated material was composed by peat mossy sediment with small admixture of mineral substratum. The both cores (70 cm) were sampled at intervals of 5 or 10 cm in 1–3 cm3. Pollen frequency was very good in all samples except samples from 10 cm. The results of the pollen analysis were illustrated in pollen diagrams compiled by the special program POLPAL. The Subboreal, the Older and Younger Subatlantic have been determined (4500 BC – to date) in Stříbrná bystřina locality and the Older and Younger Subatlantic have been determined (800 BC – to date) in Rýchory locality.
