   Pollen analysis has been carried out on a 0.38 m thick sediment profile from the Rybárenská Slať mire. The mire is situated in the central part of the Bohemian Forest westerly of the Modrava village at the elevation from 1011 to 1037 m a.s.l. Upper sediments of the mire were biostratigraphically evaluated. Its upper part was palynologically evaluated some time ago for comparison with other methods determining humolite age and conditions of its origin. Based on the results of pollen analysis, the profile of the Rybárenská Slať mire(RS, RYBS) proved to represent the younger phase of the Younger Subatlantic (Xc) and was more exactly dated by the 210Pb method into the range of 1847-1993 (the thickness of the dated sediment was 0.28 m). It seems that, in this part of the Bohemian Forest, the anthropogenic influence was much earlier and stronger; however, more natural forest still persisted. The forestation of the territory was much more pronounced here in the Bohemian Forest than in the Kru
   šné Hory Mts. On the basis of vegetation development established by the pollen analysis the profile can be divided into 4 local pollen assemblage zones (L PAZ). In the whole profile, a woody component prevailed with bigger or smaller oscillations. Only spruce (Picea) has a considerable prevalence and partly also the pine (Pinus), in this case it probably concerns types of the peat-bog dwarf pine (Pinus mugo) or the marshland pine (Pinus uncinata). The extent, method and time of farming in the Bohemian Forest can be read out from the pollen diagram, as well as two waves of resettlement in 1939 and 1945, which were reflected in the vegetation composition. A higher degree of afforestation (Picea, Fagus, Abies, Carpinus) was characteristic for the Younger Subatlantic (older phase, Xa). During Younger Subatlantic (younger phase, Xb-c), pollen of synanthropic plants appeared.
