Description :
The A. examines the geographical patterns of the Finnish mires and the role of regional and local factors that lead to their spatial differentiation. Finland can be divided into 3 roughly latitudinal mire zones (from south to north) : the raised bog zone, the aapa mire zone, and the palsa mire zone. Research on Finnish peat deposits has also shown that not all peat-stratigraphical changes are caused by past climate variations. They can also be due to the natural growth dynamics of the mires, such as the long-tern development towards drier conditions on the surface of the raised bogs, and the local changes in water table resulting from growth of hummocks and hollows.
