Abstract

The influence of different drivers on changes in North American and European boreal forests biomass burning (BB) during the Holocene was investigated based on the following hypotheses: land use was important only in the southernmost regions, while elsewhere climate was the main driver modulated by changes in fuel type. BB was reconstructed by means of 88 sedimentary charcoal records divided into six different site clusters. A statistical approach was used to explore the relative contribution of (1) pollen-based mean July/summer temperature and mean annual precipitation reconstructions, (2) an independent model-based scenario of past land use (LU), and (3) pollen-based reconstructions of plant functional types (PFTs) on BB. Our hypotheses were tested with: (1) a west -east northern boreal sector with changing climatic conditions and a homogeneous vegetation, and (2) a north -south European boreal sector characterized by gradual variation in both climate and vegetation composition.
