| Abstract: | Percentage pollen diagrams showing the colonization and development of spruce at Kolmården were established from two adjacent sites: (1) in dy from an enclosed lake and (2) in pine bog peat from the filled lake plain in the southern section of the same lake. Twenty-three radiocarbon datings from the lake dy, and 16 from the adjacent pine bog peat were processed to yield the dates of the interesting levels in the pollen diagrams. The rational limit and development of Picea is discussed in detail. Traces of late human influence are noted. The radiocarbon results from the lake are apparently a few hundred years too early. The peat yields more reliable ages. |
