“…Picea abies was planted in the northern part of the Linje peatland after the establishment of the nature reserve there in 1901 AD (Bo nski and Bo nska, 2004). Given that spruce reaches maturity at the age of~40 (Rispens, 2003;Matthias and Giesecke, 2014), the radionuclide-inferred chronology is in excellent agreement with this biostratigraphic assessment.…”

“…Numerous modern approaches allow for quantitative or semiquantitative vegetation reconstruction. For example, pollen accumulation rates provide taxon-independent values of abundance and can be directly linked to plant (tree) biomass (e.g., Seppä et al 2009;Matthias & Giesecke 2014). Unfortunately, due to discontinuous sedimentation in some of our bog records, we lacked high-quality pollen-accumulation rates essential for such approaches.…”

Forests cover approximately one-third of Central Europe. Oak (Quercus) and European beech (Fagus sylvatica) are considered the natural dominants at low and middle elevations, respectively. Many coniferous forests (especially of Picea abies) occur primarily at midelevations, but these are thought to have resulted from forestry plantations planted over the past 200 years. Nature conservation and forestry policy seek to promote broadleaved trees over conifers. However, there are discrepancies between conservation guidelines (included in Natura 2000) and historical and palaeoecological data with regard to the distribution of conifers. Our aim was to bring new evidence to the debate on the conservation of conifers versus broadleaved trees at midelevations in Central Europe. We created a vegetation and land-cover model based on pollen data for a highland area of 11,300 km in the Czech Republic and assessed tree species composition in the forests before the onset of modern forestry based on 18th-century archival sources. Conifers dominated the study region throughout the entire Holocene (approximately 40-60% of the area). Broadleaved trees were present in a much smaller area than envisaged by current ideas of natural vegetation. Rather than casting doubt on the principles of Central European nature conservation in general, our results highlight the necessity of detailed regional investigations and the importance of historical data in challenging established notions on the natural distribution of tree species.

“…Pollen and microcharcoal influx data are an estimation of the amount of pollen grains and charcoal fragments deposited in a given time (Berglund & Ralska-Jasiewiczowa 1986). Pollen influxes are therefore proportional to plant biomass and charcoal influxes to burnt biomass (Matthias & Giesecke 2014). Pollen data (single curves and "ecological" groups) as well as microcharcoal data (curves of the three dimensional fractions) are presented in Figure 2 both as influx and percentage diagrams drawn against depth and time scales using the TILIA program (Grimm 1992).…”

Wildfires in the Mediterranean basin are very important even if their causes and dynamics are not always fully understood. Fire occurrence is driven by several factors, such as the availability of fuel and the amount of biomass. In the Mediterranean basin, the seasonality of climate and its influence on vegetation plays an important role on flammability. Short-term fire dynamics and its relationship with vegetation is the subject of many present-day studies from local to global scales. Long-term fire dynamics can be investigated studying the residues of past plant burnings, such as microcharcoals. Microcharcoals extracted from lacustrine sediments are considered as a fire proxy and pollen as the best one for palaeovegetation reconstruction. We use pollen and microscopic charcoal data from a well-known Holocene sediment record from Lago di Pergusa (Sicily) to analyse their long-term relationships and to gain insights into environmental versus human-induced changes of fire behaviour. At a local scale, the fuel for wildfire is mainly provided by deciduous oaks. On the contrary, irrespective of the regional or local scale of analysis, Mediterranean vegetation seems not particularly fire-prone. Our data show that the largest fires occurred when the precipitation amount in the study area was sufficiently high to allow the development of all vegetation belts, from the Mediterranean to the montane one. Even if no doubt is left on the role of anthropogenic pressure in Sicily in the last few millennia, nonetheless our data highlight the relevant role of climate forcing on wildfires, which is mainly related to regional forest cover and, hence, to biomass and fuel availability.
