Late Quaternary Vegetational History of the North York Moors. IV. Seamer Carrs

Late Devensian and Flandrian vegetational history is describedfrom a site in an area of lowland immediately adjacent to the North York Moors. Pollen stratigraphy accompanied by a radiocarbon date of 13,000 B.P. indicates that Late Devensian vegetational changes included an interstadial characterized by two periods of Betula-dominated woodland, which were separated by one when more open conditions prevailed. The early Flandrian, in which firstly a Betulaand later a Quercus-dominated closed forest cover developed has similar vegetational characteristics to those of the adjacent North York Moors. Later Flandrian time, while reflecting the general pattern of forest reduction in adjoining regions, presents some peculiar local changes which seem to have occurred over a relatively limited area in response to the influence of successive cultural groups.
