Hellberg, E. 2004. Historical variability of deciduous trees and deciduous forests in northern Sweden. Effects of forest fires, land-use and climate. Doctor’s dissertation. ISSN 1401-6230, ISBN 91-576-6542-7. The aim of the work underlying this thesis was to study the historical variability of deciduous trees and deciduous forests in northern Sweden. To ascertain the effects of forest fires and human activities on the historical variability of deciduous trees, retrospective studies were carried out at different. These studies were designed to: improve our understanding of the genesis of deciduous forests in the present boreal landscape; the role of forest fires and effects of forest management on the structure and composition of sprucedominated ecosystems; develop methods to separate charcoal fragments of birch based on wood anatomy, to be able to; study the effects of past human activities on forest-limit ecosystems in northern Sweden. Different sets of retrospective methods (i.e. dendroecology, pollen analysis, anthracology and analyses of written historical sources) were used to achieve these aims. The first study revealed that the effects of aggregated disturbances (forest grazing, human
