Description
  • The Prášilské Lake is the glacial lake in the Bohemian Forest located on the Czech side in the elevation of 1,079 m above sea level. The lake area is 4 ha, the maximal depth is 15.5 m. The lake catchment area is situated in the sub-alpine zone. The studied area has never been the object of forest or agricultural farming in the history because of its inaccessibility. The sediment dating was carried out by means of lead isotope 210Pb. This dating was used for the deepest layer of sediment and its age was dated to the year of 1843 and a base of this profile to the medieval age, which corresponds to about the 12th-13th century A.D. The analysed profile can be divided into the local pollen assemblage zones PRI-1 (0.37-0.47 m), PRI-2 (0.25-0.37 m), PRI-3 (0.12-0.25 m), PRI-4 (0.06-0.12 m), PRI-5 (0.02-0.06 m), PRI-6 (0-0.02 m). On the basis of dating by the 210Pb method the age of sediment (0-0.11 m) is established into the range of 1843 to 1994.The rich woody component is formed mainly by pollen grains of Picea and Fagus. The herbaceous component(NAP) is very diverse; however, in a general way the pollen grains of woody species (AP) predominate due to the above mentioned deciduous forests. A representation of the herbaceous component (NAP) is very varied as far as species are concerned, human influence is very visible here (e.g. occurrence of cereals Cerealia, Zea mays, Fagopyrum-type, weed: Centaurea cyanus, Agrostemma githago etc.). The dating of this part also corresponds to the results of the pollen analysis. Of the plants producing spores the findings of lesser clubmoss (Selaginella-type cf. Selaginella selaginoides) and water plant quillwort (Isoëtes), whose nearest contemporary place of the finding in our territory is in the Černé and Plešné Lake and Wielki Staw(the Giant Mts), were quite interesting. The most of spores were recorded at the family Polypodiaceae and green alga Botryococcus, which indicate cold and humid conditions of the occurrence.
