The postglacial vegetational history in the region of Weedon has been studied by pollen analysis of a peat bog and lake sediments. Initial tundra vegetation has been re-placed by the forest, at about 11 000 B.P. Spruce established first, followed by fir stands (10 600 B.P.) and, last, maple communit...
