چکیده انگلیسی
For the first time a pedoanthracological study was undertaken in the Black Forest, SW Germany, considering forest soils in the highest altitudes of this region. For this purpose a total of ten soil profiles were studied in the Southern Black Forest, namely each two parallel profiles in high altitudes of five summit areas. Our pedoanthracological approach includes extraction and taxonomic analysis of soil charcoal fragments as well as quantification of soil charcoal concentration. The main aims of our investigation were the verification of significant charcoal residues and their distribution and concentration within the soil on different spatial scales, as well as the taxonomic analysis of single charcoal pieces. In total, 37 g charcoal were extracted from the soil samples, which yielded 2240 charcoal fragments suitable for taxonomic analysis. Most pieces of charcoal have been established of maple (Acer), followed by fir (Abies) and spruce (Picea). Only 31 charcoal pieces of beech (Fagus) were found, which represent 1.8 % of total extracted charcoal. The four tree taxa mentioned are the most common one of the potential natural vegetation (mature forests). Species of these taxa continue to be important components in the study areas. Today norway spruce (Picea abies) is dominating in the upper montane belt of the Southern Black Forest by far, followed by beech (Fagus sylvatica), while silver fir (Abies alba) is rare. Currently sycamore maple (Acer pseudoplatanus) is frequently found in the upper montane belt, but usually with proportions of less than 10 %. The pedoanthracological results of the five study sites indicate an increase in Picea-share geographically from west to east as well as orographically with increasing altitude. Charcoal concentrations of the magnitudes established suggest that for the most part the soil charcoal found is the result of natural forest fires.
