Geomorphological processes in (pre)history may have resulted in a modification of the local relief around archaeological sites, especially in areas that are prone to sediment erosion and relocation, such as sheet sand and dune landscapes. In this study, we reconstructed and analysed the palaeorelief of an archaeological excavation site in an inland dune area in southern Brandenburg, Germany. The remains of two Mesolithic sites were documented in the archaeological excavations and found to be associated with a buried soil horizon. To gather information on the relief of the buried soil surface, we used a combination of sedimentological and pedological profile descriptions along archaeological survey trenches and geophysical prospection with ground penetrating radar supplemented with microdrone photography and photogrammetry, global positioning system (GPS) surveys, and analysis of LiDAR-based elevation models. A digital elevation model of the buried surface was generated and analysed using a geographical information system (GIS). A comparison of the palaeosurface model with the recent surface elevation model shows that sand remobilization resulted in a considerable reshaping of the relief. Further, an analysis of the buried surface model shows that the relief position of the two archaeological sites in the study area was considerably more prominent in relation to the corresponding buried soil surface than in relation to the recent surface morphology. The results affirm the significance of Holocene sediment relocation for the local surface morphology and the importance of considering such relief modifications in archaeological surveys.}, language = {en} } @inproceedings{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Alexandra and Bonhage, Alexander and Raab, Thomas}, title = {Bodenver{\"a}nderungen durch die historische Holzkohleproduktion in Brandenburg}, series = {Abstracts der Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, G{\"o}ttingen, 2017}, booktitle = {Abstracts der Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, G{\"o}ttingen, 2017}, publisher = {DBG}, address = {G{\"o}ttingen}, pages = {1}, language = {de} } @inproceedings{RaabRaabTaklaetal., author = {Raab, Thomas and Raab, Alexandra and Takla, Melanie and Nicolay, Alexander and Hirsch, Florian and Schneider, Anna and R{\"o}sler, Horst}, title = {Integrative Application of Traditional and Cutting-Edge Techniques to Reconstruct Holocene Earth Surface Processes and Landscape Dynamics - A Case Study from the Northern German Lowland}, series = {AGU Joint Assembly, Montreal, 2015, abstracts listing}, booktitle = {AGU Joint Assembly, Montreal, 2015, abstracts listing}, pages = {135 -- 136}, abstract = {This study outlines the opportunities to reconstruct Holocene landscape dynamics in active opencast lignite mines in southern Brandenburg (Germany). Studies on extensive outcrops that address geomorphology, pedology and archaeology provide unique insights into human-induced environmental changes. Our approach uses a variety of traditional and cutting-edge techniques to characterize small-scale landforms (high-resolution DEMs by micro-drone and LiDAR), to analyze soils and substrate properties in the field (GPR, ERT, geomagnetics, Field Portable XRF and XRD) and to provide chronological information (OSL, 14C, tree-ring dating). This approach is combined with a GIS for data integration. We present the most recent results and review important findings from the last several years. Studies conducted in the opencast mines focus on soil development and Late Quaternary geomorphodynamics and as well as past land use and the legacy of agriculture and woodland use. Our results regarding the human-induced geomorphodynamics are similar to those in other regions in Central Europe, but we also observe regional differences caused by the local setting, e.g., intensification of soil erosion coinciding with the expansion of farming of cultivated lands in the Slavic Middle Ages. By analyzing LiDAR data the largest area of historical charcoal production in the Northern European Lowland (NEL) has been revealed. We are clearly only beginning to understand the massive dimensions of charcoal production in the region and the impact on late Holocene geomorphodynamics. The usage of new high-resolution imagery is essential to identify small-scale anthropogenic landforms hidden in the landscape. Future work will consist of developing and improving our integrative approach.

As remains of the historic charcoal kilns, small mounds of sediment rich in charcoal fragments and ash cover the soil surface. We applied a combination of methods for mapping such kiln relicts across a range of scales, in order to analyze the spatial distribution of kiln sites and to improve the understanding of historic forest use systems. In archaeological excavations in the mine forefield, the geometry of kiln relicts could be studied in high detail. We used a microdrone to record high-resolution photographs of excavation sites for the documentation of kiln site ground plans and other traces of historic land use. Based on airborne laser scanning elevation models, kiln site mapping was extended to areas beyond the mine forefield. Manual digitization from shaded relief maps was used for mapping kiln sites in further woodland areas surrounding an historic ironwork north of Cottbus. An automated mapping approach based on template matching was developed to detect charcoal production fields on a larger scale, and was applied for an area of about 1000 km2up to now. In archaeological excavations, about 900 kiln sites have been documented on an approximately 17 km2 large area. Excavation documentations and aerial photographs show variations in the kiln site ground plans. By manual digitization from Shaded Relief Maps, more than 5000 kiln sites with diameters up to 29 m were detected in the 32 km2 area of the royal forest J{\"a}nschwalder Heide north of Cottbus.

The remains of charcoal hearths are therefore a widespread legacy of historic land use in forest areas. Soils on charcoal hearth sites are characterized by a technogenic layer rich in charcoal and ash on top of the soil profile, and by a pyrogenic modification of substrates below the former hearth. The aims of our study are to examine how these alterations to the natural soil profiles affect the soil water regime and other soil physical properties, and to assess the relevance of these effects on the landscape scale. We present first results of a mapping of hearth site occurrence in forest areas in the state of Brandenburg, Germany, and of a characterization of the infiltration behaviour on hearth sites as compared with undisturbed forest soils. Results of mapping small-scale relief features from LIDAR-based digital elevation models show that charcoal hearths occur in a high density in many large forest areas throughout Brandenburg. In the areas studied so far, up to almost 3\% of the soil surface were found to be affected by the remains of historic hearths. First analyses of soil physical properties indicate differences in the infiltration characteristics of hearth site soils and undisturbed forest soils: Hood infiltrometer measurements show a very high spatial variability of hydraulic conductivity for hearth site soils, and water-drop-penetration-time tests reflect extremely high hydrophobicity of the technogenic layer on the sites. Results of dye tracer experiment show considerably strong preferential flow and therefore a higher spatial variability of soil wetness below the hearth remains. Overall, our first results therefore indicate that the legacy effects of historic charcoal production might significantly affect overall site conditions in forest areas with a high density of charcoal hearth remains.}, language = {en} } @inproceedings{HirschSchneiderRaabetal., author = {Hirsch, Florian and Schneider, Anna and Raab, Alexandra and Raab, Thomas and Ouimet, William and Dethier, David}, title = {Late Holocene biochar enrichment in soils -

Depending on region and age, RCHs have diameters CAA 2019 305 Poster session up to 30 m, and due to their size and shape they are nowadays often identified by GIS-analysis of widely available LiDAR data. We study the architecture and soil stratigraphy of RCHs in several type regions in the USA and Germany where high densities of RCHs are known (Connecticut, New Hampshire, Pennsylvania and Brandenburg, Bavaria) and propose a morphological classification scheme. Whereas RCHs on flatland mostly have a circular shape which is often surrounded by an about half a meter-wide ditch, RCHs on slopes are mostly elliptical and often have a different architecture than on flatland sites. While the RCH platforms in flatland are only about 30 cm higher than the surrounding area, the platform of RCHs on slopes has often a height of up to one meter in downslope direction. Therefore, RCHs on slopes are much easier to identify during GIS mapping than RCHs on flatland. Remarkably the size, shape and architecture between our studied RCHs in the USA and Germany are often very similar which could indicate common roots of collier's knowledge and technology that can be explained by immigration of European craftsmen to New England in the 18th and 19th century.}, language = {en} } @misc{SchneiderHirschBonhageetal., author = {Schneider, Anna and Hirsch, Florian and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {Verbreitung und Eigenschaften von Meilerb{\"o}den in Brandenburg}, series = {Erfassung und Bewertung von vorindustriellen Meilerstandorten - Workshop 19.

Methods A group of 18 patients with TGA performed an established real-space navigation paradigm, requiring allo- and egocentric spatial orientation abilities, 3 days (postacute stage) and 3 months (follow-up) after symptom onset. Visual exploration behavior and navigation strategy were documented by a gaze-controlled, head-fixed camera. Allo- and egocentric spatial orientation performance was compared to that of 12 age-matched healthy controls. Navigation-induced brain activations were measured using [18F]-fluorodeoxyglucose-PET in a subgroup of 8 patients in the postacute stage and compared to those of the controls. Results In the postacute stage, the patients navigated worse and had higher error rates than controls in allocentric (p = 0.002), but not in egocentric, route planning (p = 0.30), despite complete recovery of verbal (p = 0.58) and figural memory (p = 0.11). Until follow-up, allocentric navigation deficits improved, but higher error rates and reduced use of shortcuts persisted (p < 0.0001). Patients still exhibited relatively more fixations of unique landmarks during follow-up (p = 0.05). PET measurements during the postacute stage showed increased navigation-induced brain activations in the right hippocampus, bilateral retrosplenial, parietal, and mesiofrontal cortices, and cerebellar dentate nucleus in patients compared to controls (p < 0.005).

In this context, soil conditions may play a crucial role, since they determine the availability of water and nutrients for trees. Yet, effects of systematically differing soil conditions on tree growth render a marginally studied topic. In this context, relict charcoal hearths (RCH) - a widespread legacy of anthropogenic charcoal production - render a valuable 'natural' experiment to study possible effects of artificially altered soil conditions on tree growth. We hypothesize, that the differing physico-chemical properties of RCH result in differing wood properties if compared to trees growing on unmodified soils. To test this hypothesis, we analyzed tree-growth, wood density, and wood elemental concentrations of Scots pine as well as physico-chemical soil properties. We applied a classic control-treatment design to compare RCH with unmodified soils. Our analyses identified significantly lower above-ground wood production but systematically higher wood elemental concentrations in RCH-trees compared to control trees. Since we could not identify treatment-specific growth patterns, we hypothesize the observed lower above-ground productivity of Scots pine to indicate an increased root-shoot ratio to compensate for a potentially lower plant water availability on RCH-sites.

This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental research protocols. To provide further evidence on whether competition affects moral behavior and to examine whether the generalizability of a single experimental study is jeopardized by design heterogeneity, we invited independent research teams to contribute experimental designs to a crowd-sourced project. In a large-scale online data collection, 18,123 experimental participants were randomly allocated to 45 randomly selected experimental designs out of 95 submitted designs. We find a small adverse effect of competition on moral behavior in a meta-analysis of the pooled data. The crowd-sourced design of our study allows for a clean identification and estimation of the variation in effect sizes above and beyond what could be expected due to sampling variance. We find substantial design heterogeneity—estimated to be about 1.6 times as large as the average standard error of effect size estimates of the 45 research designs—indicating that the informativeness and generalizability of results based on a single experimental design are limited.

We studied soils at former charcoal production sites (relict charcoal hearths, RCHs) and compared these soils with undisturbed soil next to the charcoal hearths and four typical soils on similar parent material located at distances between 10 and 70 km from the RCHs. In a landscape typical of the northern German lowland, we found Podsolige Braunerde [WRB: Brunic Arenosols (Protospodic)] outside of the RCHs and soils with a clearly different stratigraphy within the RCHs. The main feature of the soils at both of the studied RCHs is a heterogeneous, charcoal-bearing deposit that is ~30 cm thick. No indications of translocation or mineral transformation processes, which form distinct soil horizons after the deposition of anthropogenic material on the RCHs, are present. Except for the differences in color and total carbon content, the soil chemistry of the RCHs hardly differs from that of the soil outside of the charcoal hearth sites. The soil colors and magnetic susceptibility values strongly suggest that the RCH substrates and the underlying topsoil were affected by thermally induced transformation of iron (hydr-)oxides. Although the charring procedure normally requires ~2 weeks, the heating effect only reaches to a maximum depth of 8 cm into the buried soil below the charcoal hearths. The presence of reddish soil and an abrupt increase in magnetic susceptibility in the upper 2 cm of the soil below the charcoal hearths indicate the heat-induced transformation of iron (hydr-)oxides into maghemite. Brighter soil color and an increase in soil organic matter (SOM) in the lower parts of the buried topsoil demonstrate the combustion of SOM up to 5 cm depth below the RCH. According to the German Guidelines for Soil Mapping, the soils in the RCHs are classified as Regosols above Braunerde [WRB: Spolic Technosols (Arenic)]. However, because the anthropogenic features of these soil sediments are disregarded in the German Guidelines for Soil Mapping, we suggest adapting the "M" horizon to permit a jM horizon.

One of the striking characteristics of a RCH site regardless of its architecture is the enrichment of the soil with charcoal in varying particle sizes. In this study, we use chemical digestion coupled with a PLSR-model to quantify organic carbon and pyrogenic carbon in RCH substrate by MIR-DRIFT measurements.

The history and technique of charcoal production are described to clarify legacy effects. Applying a recently presented morpho-genetic catalogue is useful for classified mapping of RCH findings. The RCH numbers and calculated RCH densities per study region vary greatly and impose uncertainties due to insufficient methods causing over- or underestimations. Areas with high RCH densities between 50 and 500 RCH/km2 seem reasonable. Machine learning-based remote sensing techniques are promising approaches with which to better assess the full scale of charcoal burning legacies. RCH soil properties feature dark charcoal-rich technogenic substrate layers classified as Auh horizons according to the World Reference Base with significantly increased C contents. These Auh horizons can also exhibit specific physical and chemical properties, such as relatively low bulk density, high porosity, high plant available water content, low thermal conductivity and differences in cation exchange capacity or nutrient status. However, relevant studies are rare, and thus, the effects may differ by study region. Regarding vegetation, there seem to be four main effects: changes in forest structure, species composition, recruitment pattern and productivity. The number of studies on this issue is, however, also very limited. Even fewer studies have examined the soil fauna in RCHs; thus, the reported effects cannot be used to draw general conclusions.

Dendrochronological dating of large charcoal pieces has identified RCH ages ranging from 1709 AD to 1823 AD for a subarea in the Tauer Forest, which allows for assessing century old effects of charcoal application on forest soils. We measured the geometry and soil organic matter (SOM) content of 20 RCH sites in a selected part of the forest. The results provide a basis for estimating RCH SOM stocks on a 40-ha forest plot with 120 RCH sites. We also assessed the accuracy of RCH mapping based on digital elevation models (DEMs) with results from a ground survey. Over 50 \% of sites were not detected by the DEM-based mapping. In the range of statistical uncertainties, RCHs add between 18 \% and 32 \% of SOM to the stock of the natural forest soil in the study area. This equals an additional 4.9 - 8.9 Mg of carbon per hectare of forest soil. These substantial amounts of SOM are so far not recognized by any survey or forest soil SOM inventories.

The archaeological discovery of a large charcoal burning area in the forefield of the active opencast lignite mine J€anschwalde in SE Brandenburg (North German Lowlands) has highlighted the need for multidisciplinary research in the study of the dimensions of historical charcoal burning. The charcoal produced in our study area, the former royal forest district Tauer, provided energy for the nearby Peitz ironworks during its operation from the mid-16th to the mid-19th century. Here, we aimed to record the amount, size and distribution of relict charcoal hearths (RCHs) to examine their context with respect to the ironworks and to better understand the potential impacts on late Quaternary landscape change. The applied methods combined archaeological research with shaded-relief mapping of RCHs. To evaluate the detection success of RCHs in the shaded-relief maps (SRMs), we compared the results with the results from specific archaeological surveys and conventional forest site mapping. Furthermore, we analyzed our dataset with descriptive, comparable and spatial statistics. Additionally, dendrochronological dating of charcoal fragments from selected RCHs was used to investigate the temporal relationships among the RCHs. Approximately 6000 circular RCHs were manually digitally identified in the SRMs of the 109-km2 evaluable area. However, ground truthing showed that the shaded-relief maps could not completely capture all RCHs in our study area due to local conditions. At the regional scale, two focus areas with high RCH site densities were found. Statistical analysis revealed that the diameters of the RCHs range widely from 4 to 30.5 m. Spatial statistics were applied to the RCH diameters to aggregate areas with larger or smaller RCHs. At the small scale, no systematic arrangement of RCHs was obvious in the SRMs. Dendrochronological dating of selected RCHs lying close together could not detect significant spatiotemporal relationships or patterns. The dating results also showed that some areas have been preferentially used for charcoal production for over 300 years. Due to the homogeneity of the physiogeographical location factors, we assume that these factors are not superficially responsible for site selection. Instead, economic location factors and contemporary regulations are more likely responsible for the distribution of RCHs.}, language = {en} } @misc{BonhageHirschRaabetal., author = {Bonhage, Alexander and Hirsch, Florian and Raab, Thomas and Schneider, Anna and Raab, Alexandra and Ouimet, William}, title = {Characteristics of small anthropogenic landforms resulting from historical charcoal production in western Connecticut, USA}, series = {Catena}, volume = {195}, journal = {Catena}, issn = {0341-8162}, doi = {10.1016/j.catena.2020.104896}, pages = {14}, language = {en} } @misc{HirschSchneiderBonhageetal., author = {Hirsch, Florian and Schneider, Anna and Bonhage, Alexander and Raab, Alexandra and Drohan, Patrick J. and Raab, Thomas}, title = {An initiative for a morphologic-genetic catalog of relict charcoal hearths from Central Europe}, series = {Geoarchaeology}, volume = {35}, journal = {Geoarchaeology}, number = {6}, issn = {1520-6548}, doi = {10.1002/gea.21799}, pages = {974 -- 983}, language = {en} } @misc{SchneiderHirschBonhageetal., author = {Schneider, Anna and Hirsch, Florian and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {The soil moisture regime of charcoal-enriched land use legacy sites}, series = {Geoderma}, volume = {366}, journal = {Geoderma}, issn = {0016-7061}, doi = {10.1016/j.geoderma.2020.114241}, pages = {15}, language = {en} } @misc{SchneiderBonhageHirschetal., author = {Schneider, Anna and Bonhage, Alexander and Hirsch, Florian and Raab, Alexandra and Raab, Thomas}, title = {Hot spots and hot zones of soil organic matter in forests as a legacy of historical charcoal production}, series = {Forest Ecology and Management}, volume = {504}, journal = {Forest Ecology and Management}, issn = {1872-7042}, doi = {10.1016/j.foreco.2021.119846}, abstract = {Human land use often leads to distinct modifications of soils within small, clearly delimited areas. Legacy effects of past land use are also abundant in recent forest areas, but are hardly considered in ecosystem assessment and soil mapping. The soils on relict charcoal hearths (RCHs) are a widespread example for such land use legacy soils in forests. Soils on RCHs differ clearly from surrounding forest soils in their stratigraphy and properties, and are most prominently characterized by a technogenic substrate layer with high contents of charcoal and thus soil organic matter (SOM). Although RCH soils can clearly contribute to the SOM stocks of forest soils, their relevance on the landscape scale has hardly been quantified. In this paper we analyze and discuss the distribution and effects of RCH soils across scales for forests in the state of Brandenburg, Germany, with a focus on SOM stocks. Our analysis is based on a large-scale mapping of RCHs from digital elevation models (DEMs), combined with a linear regression model of SOM stocks in RCH soils. The spatial distribution of RCH soils in the study region has a scale dependent heterogeneity. The large-scale variation in site densities is related to the concentration of charcoal production to specific forest areas while the small-scale variation is related to the irregular distribution of single RCHs within the charcoal production fields. Up to 1.5 \% of the surface are covered by RCH soils in the forest areas within the study region. The results also show that RCHs can significantly contribute to the SOM stocks of forests, even where they cover only a small fraction of the soil surface, with up to 18 \% additional SOM for forest areas. Because of the heterogeneous distribution of RCHs, the SOM stock additions depend on the scale of observation. Our results suggest that RCH SOM additions can be overestimated when sites in small areas (< 1 km²) are analyzed; and that characteristic spatial concentration patterns of RCHs are even observable when values are aggregated to large areas (25 km² and more). Aggregating effects to irregularly-sized forest administrative units resulted in maps that well represent the spatial distribution of RCH soils and SOM. The study highlights that considering land use legacy effects can be relevant for the results of soil mapping and inventories; and that prospecting and mapping land use legacies from DEMs can contribute to improving such approaches.}, language = {en} } @misc{BonhageRaabSchneideretal., author = {Bonhage, Alexander and Raab, Thomas and Schneider, Anna and Fischer, Thomas and Ramezany, Shaghayegh and Ouimet, William and Raab, Alexandra and Hirsch, Florian}, title = {Vertical SOC distribution and aromatic carbon in centuries old charcoal-rich Technosols}, series = {European Journal of Soil Science}, volume = {73}, journal = {European Journal of Soil Science}, number = {4}, doi = {10.1111/ejss.13293}, pages = {1 -- 16}, abstract = {Charcoal-rich Technosols on century-old relict charcoal hearths (RCHs) are the subject of ongoing research regarding potential legacy effects that result from historic charcoal production and subsequent charcoal amendments on forest soil properties and forest ecosystems today. RCHs consist mostly of Auh horizons that are substantially enriched in soil organic carbon (SOC), of which the largest part seems to be of pyrogenic origin (PyC). However, the reported range of SOC and PyC contents in RCH soil also suggests that they are enriched in nonpyrogenic SOC. RCH soils are discussed as potential benchmarks for the long-term influence of biochar amendment and the post-wildfire influences on soil properties. In this study, we utilised a large soil sample dataset (n = 1245) from 52 RCH sites in north-western Connecticut, USA, to quantify SOC contents by total element analysis. The contents of condensed highly aromatic carbon as a proxy for black carbon (BC) were predicted by using a modified benzene polycarboxylated acid (BPCA) marker method in combination with diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy-based partial least square regression (r2 = 0.89). A high vertical spatial sampling resolution allowed the identification of soil organic matter (SOM) enrichment and translocation processes. The results show an average 75\% and 1862\% increase in TOC and BPCA-derived carbon, respectively, for technogenic Auh horizons compared to reference soils. In addition to an increase in aromatic properties, increased carboxylic properties of the RCH SOC suggest self-humification effects of degrading charcoal and thereby the continuing formation of leachable aromatic carbon compounds, which could have effects on pedogenic processes in buried soils. Indeed, we show BPCA-derived carbon concentrations in intermediate technogenic Cu horizons and buried top/subsoils that suggest vertical translocation of highly aromatic carbon originating in RCH Auh horizons.

In this study,we used a combined geomorphological, pedological, sedimentological and palynological approach to characterize landscape development after the Last Glacial Maximum (LGM) near Lake Wygonin in Northern Poland. The pedostratigraphical findings from soil pits and drillings were extrapolated using ground-penetrating radar (GPR) and electric resistivity tomography (ERT). During the Pomeranian phase, glacial and fluvioglacial processes dominated the landscape near Lake Wygonin. At the end of the glacial period, periglacial processes became relevant and caused the formation of ventifacts and coversands containing coated sand grains. At approximately 15,290-14,800 cal yr BP, a small pond formed in a kettle hole (profile BWI2). The lacustrine sediments lack eolian sand components and therefore indicate the decline of eolian processes during that time. The increase of Juniperus and rock-rose (Helianthemum) in the pollen diagram is a prominent marker of the Younger Dryas. At the end of the Younger Dryas, a partial reshaping of the landscape is indicated by abundant charcoal fragments in disturbed lake sediments. No geomorphologic activity since the beginning of the Holocene is documented in the terrestrial and wetland archives. The anthropogenic impact is reflected in the pollen diagram by the occurrence of rye pollen grains (Secale cereale) and translocated soil sediments dated to 1560-1410 cal yr BP, proving agricultural use of the immediate vicinity. With the onset of land use, gully incision and the accumulation of colluvial fans reshaped the landscape locally. Since 540-460 cal yr BP, further gully incision in the steep forest tracks has been associated with the intensification of forestry. Outside of the gully catchments, the weakly podzolized Rubic Brunic Arenosols show no features of Holocene soil erosion.}, language = {en} } @inproceedings{SchneiderRaabBonhageetal., author = {Schneider, Anna and Raab, Alexandra and Bonhage, Alexander and Hirsch, Florian and Raab, Thomas}, title = {Relikte der historischen K{\"o}hlerei in Brandenburg}, series = {Jahrestagung des Arbeitskreises Geoarch{\"a}ologie, M{\"u}nchen, 2018}, booktitle = {Jahrestagung des Arbeitskreises Geoarch{\"a}ologie, M{\"u}nchen, 2018}, editor = {Berg, Stefanie and Eckmeier, Eileen and Linzen, Sven and Werther, Lukas and Zielhofer, Christoph}, publisher = {Friedrich-Schiller-Universit{\"a}t Jena [u.a.]}, address = {Jena [u.a.]}, doi = {10.22032/dbt.34521}, pages = {S. 28}, language = {de} } @inproceedings{BonhageHirschSchneideretal., author = {Bonhage, Alexander and Hirsch, Florian and Schneider, Anna and Raab, Alexandra and Raab, Thomas}, title = {Multiproxy analysis of a relict charcoal hearth field in Brandenburg (Germany)}, series = {European Geosciences Union, General Assembly 2018, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2018, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{SchneiderRaabBonhageetal., author = {Schneider, Anna and Raab, Alexandra and Bonhage, Alexander and Hirsch, Florian and Raab, Thomas}, title = {Legacies of historic charcoal production in Brandenburg, Germany}, series = {European Geosciences Union, General Assembly 2018, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2018, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, language = {en} } @inproceedings{BonhageHirschSchneideretal., author = {Bonhage, Alexander and Hirsch, Florian and Schneider, Anna and Raab, Alexandra and Raab, Thomas}, title = {Multiproxy analysis of a relict charcoal hearth field in Brandenburg (Germany)}, series = {Jahrestagung des Arbeitskreises Geoarch{\"a}ologie, M{\"u}nchen, 2018}, booktitle = {Jahrestagung des Arbeitskreises Geoarch{\"a}ologie, M{\"u}nchen, 2018}, editor = {Berg, Stefanie and Eckmeier, Eileen and Linzen, Sven and Werther, Lukas and Zielhofer, Christoph}, publisher = {Friedrich-Schiller-Universit{\"a}t Jena [u.a.]}, address = {Jena [u.a.]}, doi = {10.22032/dbt.34521}, pages = {S. 27}, language = {en} } @inproceedings{SchneiderBonhageHirschetal., author = {Schneider, Anna and Bonhage, Alexander and Hirsch, Florian and Raab, Alexandra and Raab, Thomas}, title = {Spatial and temporal variability of soil physical properties on legacies of historic charcoal production}, series = {European Geosciences Union, General Assembly 2018, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2018, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {The spatial variability of soil physical properties on the landscape scale is often increased by anthropogenic land occupation, not only by current land use but also through the legacies of past land use systems. The remains of historic charcoal hearts are an example for such a disturbance of the soil landscape by former forestry. Such relict charcoal hearths (RCH) exhibit a clearly altered soil stratigraphy, most prominently characterized by a technogenic substrate layer on the soil surface, and their soil physical properties can considerably differ from those of surrounding forest soils. The aim of our study is to characterize the soil water and temperature regime on RHC in a pre-industrial charcoal production area in Brandenburg, Germany, as compared with the surrounding sandy forest soils. Soil properties were analyzed in profiles on and around hearth sites and are monitored in a sensor transect equipped with soil moisture sensors and pF-meters. Results of soil sample analyses show differences in density and porosity between the RCH soils and surrounding forest soils, not only in the technogenic layer but also in the buried soil layers on hearth sites. The soil water characteristic curves determined in the laboratory indicate a modified pore size distribution and lower plant available water contents in the RCH soils. Preliminary results of the ongoing soil water monitoring, however, show increased soil wetness in the RCH soils, along with lower soil moisture tensions. Furthermore, the measurements show higher variations of soil temperature in RCH soils. The results affirm that the legacies of historic charcoal production can increase the spatial variability of soil physical properties and therefore also of ecological site conditions in forest areas.

Geomorphological processes in (pre)history can have resulted in a modification of the local relief around archaeological sites, especially in areas that are prone to sediment erosion and relocation, so that models of past surfaces are necessary for a correct interpretation of archaeological survey results. In this study, we combined terrestrial survey and remote sensing methods to reconstruct the palaeorelief around two archaeological excavation sites in an inland dune area in southern Brandenburg, Germany. Remains from two Mesolithic hunter-gatherer camps were documented in archaeological excavations and found to be associated with a buried soil horizon. To gather information on the relief of the buried soil surface, we used a combination of sedimentological and pedological profile description of archaeological survey trenches and geophysical prospection with Ground-Penetrating Radar; supplemented by microdrone photography and photogrammetry, GPS surveys and analysis of LIDAR-based elevation models. A digital elevation model of the buried surface was created by combining point data from these sources. The buried surface morphology and the position of the archeological remains within the reconstructed landscape were analyzed in GIS. The comparison of the generated paleosurface model with the recent surface elevation model shows that sand remobilization resulted in a considerable reshaping of the relief. Analysis of the buried surface model further shows that the relief position of the two archaeological sites in the study area was considerably more prominent in relation to the corresponding buried soil surface than in relation to the recent surface morphology.

Information on theses parameters was gathered in an archive and literature study and from historical and recent maps. Areas with a high probability of kiln site occurrence were then determined using a simple binary additive model. In the last step, shaded-relief maps (SRMs) were visually checked for clearly visible kiln sites and soil properties were analysed in the determined areas. In total, eight areas with a high probability of kiln site occurrence are identified for the state of Brandenburg. By visual interpretation of SRMs, high kiln site densities in these areas are confirmed. The analysis of soil maps shows that kiln fields are predominantly located on sandy soils with a low yield potential.

The charcoal was mainly produced for the ironwork Peitz nearby, which operated from the 16th to the mid-19th centuries. In a first approach, to estimate the dimension of the charcoal production, CKRs were mapped on shaded-relief maps (SRMs) derived from high-resolution LiDAR data (Raab et al. 2015). Subsequently, for a selected test area, identified CKRs on the SRMs were compared with archaeologically excavated CKRs in the field. This survey showed a considerably number of falsely detected sites. Therefore, the data was critically re-evaluated using additional relief visualisations. Further, we extended the CKR mapping to areas which are not archaeologically investigated. The study area, the former royal forest district Tauer, consists of two separate areas: the Tauersche Heide (c. 96 km2 area) N of Peitz and the area J{\"a}nschwalde (c. 32 km2 area) NE of Peitz. The study area is characterized by a flat topography. Different former and current anthropogenic uses (e.g., military training, solar power plant, forestry measures) have affected the study area, resulting in extensive disturbances of the terrain surface. The revised CKR abundance in the study area J{\"a}nschwalde was considerably smaller than the numbers produced by our first approach. Further, the CKR mapping revealed, that a total record of the CKRs is not possible for various reasons. Despite these limitations, a solid database can be provided for a much larger area than before. Basic statistic parameters of the CKR diameters and all comparative statistical tests were calculated using SPSS. To detect underlying spatial relationships in the CKR site distribution, we applied the Getis-Ord Gi* statistic, a method to test for local spatial autocorrelation between neighbouring sites.

RCH sites are characterized bya substantial admixture of charcoal fragments of varying particle sizes constituting an anthropogenic addition of carbon to the natural forest soil. Ages of about 250 years proven by dendrochronological dating of larger charcoal pieces on RCHs allow for assessing long-term effects of biochar application on forest soils. In this study, we measured the geometry and SOM content of 20 RCH sites in a selected part of the forest district. The results are the basis for a projection of RCH SOM stocks on a 40 ha forest plot with 120 RCH sites. In the range of statistical uncertainties it is shown that RCHs add between 13 \% and 32 \% of SOM to the SOM stock of the natural forest soil in the studied plot. These substantial amounts of SOM are so far not recognized by any soil survey or forest soil inventories of SOM and SOC stocks. In light of an increasing amount of studies that detect RCH sites in forests of Europe and the USA in the range of tens-and even hundreds of thousands, the question has to be asked how to address this legacy effect in ongoing scientific discussions about soil carbon stocks, carbon sequestration and the long-term effects of biochar application into soils.}, language = {de} } @inproceedings{HirschNicolaySchneideretal., author = {Hirsch, Florian and Nicolay, Alexander and Schneider, Anna and Błaszkiewicz, Mirosław and Kordowski, Jarosław and Noryskiewicz, Agnieszka M. and Tyszkowski, Sebastian and Raab, Alexandra and Raab, Thomas}, title = {Sp{\"a}tquart{\"a}re Landschaftsentwicklung seit der Pommerschen Phase in Wygonin (Nordpolen)}, series = {Jahrestagung des AK Geomorphologie in Kiel 2014}, booktitle = {Jahrestagung des AK Geomorphologie in Kiel 2014}, editor = {Bork, Hans-Rudolf and Dreibrodt, Stefan and Duttmann, Rainer and Unkel, Ingmar}, publisher = {Christian-Albrechts-Universit{\"a}t}, address = {Kiel}, pages = {S. 66}, language = {de} } @inproceedings{HirschRaabSchneideretal., author = {Hirsch, Florian and Raab, Thomas and Schneider, Anna and Wechler, Klaus-Peter}, title = {Late Holocene eolian fossilization of Podzols in Northeastern Germany}, series = {European Geosciences Union, General Assembly 2016, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2016, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {The North European lowland has been formed by glacial and periglacial processes in the Late Pleistocene. Multiple reshaping since the Late Glacial considerably changed the landscape up to and including especially historic times. Sediment sequences and (fossilized) soils can improve our understanding of Late Quaternary landscape development, but mapping of buried soils and surfaces is often limited to single outcrops. Ongoing archaeological rescue excavations in the pre-field of the open-cast mine Cottbus-Nord (northeastern Germany) with dense excavation trenches in an about 10 ha dune and drift sand area reveal multilayered sediment sequences with fossilized soils and sediments from the Late Pleistocene to the Late Holocene. Archaeological findings ranging from Mesolithic flint stones to an about 200 year old ceramics in eolian sediments covering plow horizons and wheel tracks suggest that eolian relocation of sandy material was intensive about 200 years ago. Still unpublished OSL dating underline the intense eolian activity. Recent studies showed that between the 15Th to the 19Th century an iron smelter 5 km to the west of our study site was supplied with charcoal, which was produced in a forest 5 km east to our study site. Our current findings about Late Holocene eolian activity raise the question if this eolian reshaping of the landscape is connected with the operation of the iron smelter either directly by transport or bog iron ore winning or indirectly by population pressure caused by the prospering iron smelter.

The increasing availability of high-resolution ALS data has given rise to many recent studies mapping such land use legacy features, which have revealed impressively high numbers and spatial densities of RCHs in many regions of the world. Nevertheless, the limitations of mapping from remotely-sensed data still need to be considered to allow for meaningful interpretations of RCH spatial distribution patterns and conclusions on past forest use. We present an assessment of the possibilities and limitations of RCH mapping from ALS data on the landscape scale, comparing mapping results from study areas in the Northeastern German Lowlands, the German lower mountain ranges and the lower mountain ranges in the northeastern USA. RCHs were mapped using automated detection and manual digitization, and mapping results were validated against archaeological excavations and detailed field surveys. The results allow for a detailed analysis of mapping accuracy in relation to DEM resolution and feature size, but furthermore show up relations of mapping success to RCH age and preservation and to geomorphology and subsequent forest use. Results CAA 2019 279 Standard session 42: New technologies in woodland archaeology: problems and limitations from a GIS analysis of RCH spatial distribution in relation to historic charcoal-consuming industries affirm that RCHs are a widespread and underestimated legacy of past woodland use in many regions, but also underline the relevance of considering variable mapping accuracy in landscape-scale analyses of archaeological relief features mapped from ALS data.}, language = {en} } @misc{NeyretLeProvostBoesingetal., author = {Neyret, Margot and Le Provost, Ga{\"e}tane and Boesing, Andrea Larissa and Schneider, Florian D. and Baulechner, Dennis and Bergmann, Joana and Vries, Franciska T. de and Fiore-Donno, Anna Maria and Geisen, Stefan and Goldmann, Kezia and Merges, Anna and Saifutdinov, Ruslan A. and Simons, Nadja K. and Tobias, Joseph A. and Zaitsev, Andrey S. and Gossner, Martin M. and Jung, Kirsten and Kandeler, Ellen and Krauss, Jochen and Penone, Caterina and Schloter, Michael and Schulz, Stefanie and Staab, Michael and Wolters, Volkmar and Apostolakis, Antonios and Birkhofer, Klaus and Boch, Steffen and Boeddinghaus, Runa S. and Bolliger, Ralph and Bonkowski, Michael and Buscot, Fran{\c{c}}ois and Dumack, Kenneth and Fischer, Markus and Gan, Huei Ying and Heinze, Johannes and H{\"o}lzel, Norbert and John, Katharina and Klaus, Valentin H. and Kleinebecker, Till and Marhan, Sven and M{\"u}ller, J{\"o}rg and Renner, Swen C. and Rillig, Matthias C. and Schenk, No{\"e}lle V. and Sch{\"o}ning, Ingo and Schrumpf, Marion and Seibold, Sebastian and Socher, Stephanie A. and Solly, Emily F. and Teuscher, Miriam and Kleunen, Mark van and Wubet, Tesfaye and Manning, Peter}, title = {A slow-fast trait continuum at the whole community level in relation to land-use intensification}, series = {Nature Communications}, volume = {15}, journal = {Nature Communications}, number = {1}, issn = {2041-1723}, doi = {10.1038/s41467-024-45113-5}, abstract = {AbstractOrganismal functional strategies form a continuum from slow- to fast-growing organisms, in response to common drivers such as resource availability and disturbance. However, whether there is synchronisation of these strategies at the entire community level is unclear. Here, we combine trait data for 2800 above- and belowground taxa from 14 trophic guilds spanning a disturbance and resource availability gradient in German grasslands. The results indicate that most guilds consistently respond to these drivers through both direct and trophically mediated effects, resulting in a 'slow-fast' axis at the level of the entire community. Using 15 indicators of carbon and nutrient fluxes, biomass production and decomposition, we also show that fast trait communities are associated with faster rates of ecosystem functioning.

Open questions about RIFU formation and potential legacy effects still exist, especially related to physical soil properties. Aims Our aims were (1) to characterize the soil properties of RIFU soils and (2) to compare the drought sensitivity and the growth resistance in extremely dry years of trees growing on ridges and furrows, respectively. Methods We studied soil physical (bulk density, saturated soil hydraulic conductivity, and texture) and chemical (soil pH, soil organic matter, and nitrogen content) properties and the climate sensitivity of tree growth on RIFU systems for three study sites in Prignitz, Germany. Results RIFU systems showed a high spatial heterogeneity of soil stratigraphy due to ridge construction and increased accumulation of soil moisture and organic matter in furrows due to post-abandonment pedogenesis. Slight spatial differences in soil physical properties were found, with increased air capacity in ridge soils and higher available water contents in furrow soils. No differences in drought sensitivity were observed for trees growing on ridges and furrows, except for a wet site, where trees in furrows showed a higher sensitivity. Resistance in dry years tended to be similar or increase from furrows to ridges. Conclusions The results reflect a spatial differentiation of stratigraphy and post-abandonment pedogenesis on abandoned RIFU systems and suggest an adaption to different moisture conditions through RIFU construction. Differences in drought sensitivity of tree growth with relative land surface could only be detected for one of the three sites, where trees were found to be less drought sensitive on ridges.}, language = {en} }
