Pollen analysis and vegetional history of the ‘akeld’ basin

Abstract

A pollen diagram has been constructed for the Akeld Steads region of the Glen Valley in Northumberland. This diagram provides an interesting variation in the vegetational history of the area. Evidence suggests that although the late post glacial vegetation was similar to that of the rest of the region, Quercus appeared before Ulmus in this area. This feature is contrary to the usual pattern suggested, however, it is seen on other northern diagrams but has not been commented upon by their authors. The persistence of pine in the area until the late Boreal period may beassociated with the Cheviot Hills which overlook the basin. The lack of deposit during the late Boreal and early Atlantic periods may be attributed to local hydrologica conditions prevailing at that time. There is some evidence for the presence of Man In the area from the Boreal period onwards. This evidence comes from the pollen diagram and stratigraphy of the site and is further substantiated by the archaeological discoveries made in the area.
