Various land use forms result in distinct alterations of surface morphology, which are often well preserved but rarely described within forest areas. The interpretation of LiDAR Digital Elevation Models (DEMs) can greatly enhance our insight into the geoarchaeological records of woodlands. This study examines the legacies of past land use in forested areas of Upper Palatinate, Germany, utilizing LiDAR DEMs to map anthropogenic relief features. We comprehensively mapped land use legacy landforms (LULLs) that occur with considerable frequency in the study area, that is, former agricultural field systems, road remnants, abandoned ponds, relict charcoal hearths, mining legacies, and indicators of anthropogenically induced soil erosion. Results reveal that 17\% of the forested area is affected by LULLs, with the largest areas covered by former field systems, roads, and ponds. Characteristic LULL associations reflect past agricultural and charcoal production landscapes. While erosion indicators often coincide with field systems and roads, natural factors mainly influence their distribution. Comparison with historical maps suggests pre-19th-century abandonment of most LULLs and good preservation of anthropogenic relief modifications. Our results underscore the enduring impact of past land use on present woodland ecosystems and emphasize the importance of considering forest areas in the analysis of past human-landscape interactions.}, language = {en} } @misc{BonhageRaabDrohanetal., author = {Bonhage, Alexander and Raab, Thomas and Drohan, Patrick and Schneider, Anna and Raab, Alexandra}, title = {An initial geopedological survey and description of historic raised beds in north-western Ireland}, series = {Geomorphology}, volume = {481}, journal = {Geomorphology}, publisher = {Elsevier}, issn = {1872-695X}, doi = {https://doi.org/10.1016/j.geomorph.2025.109778}, pages = {1 -- 12}, abstract = {Raised Bed (RB) field structures in northwestern Ireland are historical relics of widespread agriculture before and during the Great Famine in the mid-19th century. Their primary purpose was to improve drainage on shallow, waterlogged soils for cultivation of crops. Today, the undulating surface morphology created by the ridges and furrows remains visible in many locations, raising questions about how many of these historic fields actually still exist, whether they are mappable, and if their soils have undergone persistent anthropogenic changes. In this study, we analyse three different RB sites located in varying topographical positions and on different parent materials. High-resolution digital elevation models (DEMs) are created using UAV-based photogrammetry to analyse the surface morphology and model surface flow accumulation and wetness. Soils are analysed using trenches and surface samples taken from ridges and furrows. Our results indicate that satellite or aerial imagery alone is insufficient for reliably detecting RB sites, as the height difference between ridges and furrows is too subtle. Ridge spacing and furrow depth are best observed using high-resolution DEMs (<50 cm cell size). The modelled surface hydrology suggests that the drainage function of RB sites remains, with furrows retaining more moisture than ridges. This can have significant implications for microhabitat structures within RB fields, potentially influencing faunal species composition and abundance. Furthermore, we find significant differences in specific elemental concentrations between soils on ridges and soils on furrows, as well as differences in grain size distributions. These findings indicate a wide range of potential legacy effects present in RB fields that merit further investigation.}, language = {en} } @misc{JouySchueleAdhikarietal., author = {Jouy, Florent and Sch{\"u}le, Maren and Adhikari, Yojana and Binder, Anja and Clerc, Danica and Gerwin, Werner and Heinken, Thilo and Raab, Thomas and Repmann, Frank and R{\"o}nnefarth, Susanne and Schirrmacher, Marina and Schmehl, Marie-Therese and Schr{\"o}der, Jens and Ibisch, Pierre L.}, title = {Factors impacting the variability of post-fire forest regeneration in central European pine plantations}, series = {Restoration Ecology}, journal = {Restoration Ecology}, doi = {10.1111/rec.70017}, abstract = {Fire is increasingly posing a risk to forests and plantations, even in the temperate latitudes of central Europe. Little is known about fire ecology in this region, and therefore, appropriate approaches for the management and reforestation of burned sites are mostly lacking. In a Scots pine plantation region in Brandenburg (northeast Germany), the early tree regeneration of two nearby areas that burned 1 year apart was investigated. We observed that 3 years after the fire events, the forest in one study area showed a relatively high regeneration with a mean density of 7765 saplings/ha, clearly dominated by European aspen (93\%); whereas the other study area showed a lower mean density of 5061 saplings/ha, dominated by Scots pine (71\%) and aspen (15\%). Three years after the fires, the difference in aspen density was 11-fold between the two areas. We studied the effects of several variables about soil and environmental properties on the aspen establishment in these two study areas in the second and third years after the fire events. We found that the post-fire aspen regeneration was influenced by several factors, including soil texture, soil disturbance from forest management, volume of deadwood, and browsing. We also discussed that weather conditions during seed production and germination might have played a role in the difference in aspen establishment between the two study areas. We concluded that the post-fire forest regeneration potential in the study region is highly variable and could come under critical pressure as climate change progresses.}, language = {en} } @misc{SchmehlAdhikariBalthasaretal., author = {Schmehl, Marie-Therese and Adhikari, Yojana and Balthasar, Cathrina and Binder, Anja and Clerc, Danica and Dobkowitz, Sophia and Gerwin, Werner and G{\"u}nther, Kristin and Hartong, Heinrich and Heinken, Thilo and Hess, Carsten and Ibisch, Pierre L. and Jouy, Florent and Leinen, Loretta and Raab, Thomas and Repmann, Frank and R{\"o}nnefarth, Susanne and Rohlfs, Lilly and Schirrmacher, Marina and Schr{\"o}der, Jens and Sch{\"u}le, Maren and Vieth-Hillebrand, Andrea and Francke, Till}, title = {Monitoring abiotic and biotic parameters of forest regrowth under different management regimes on former wildfire sites in northeastern Germany - data from the PYROPHOB project}, series = {Earth system science data}, volume = {17}, journal = {Earth system science data}, number = {11}, publisher = {Copernicus GmbH}, address = {G{\"o}ttingen}, issn = {1866-3516}, doi = {10.5194/essd-17-6295-2025}, pages = {6295 -- 6313}, abstract = {We present the data recorded by eight institutions within the PYROPHOB project, running from 2020 to 2024 at two forest research sites in the south-west of Brandenburg, Germany. The aim of the project was to monitor abiotic and biotic parameters of forest regrowth under different management regimes on former wildfire sites in northeastern Germany. The observations comprised intermittent and continuous measurements or surveys on meteorological parameters (rainfall, temperature, vapour pressure deficit), soil (soil type and texture, soil chemistry and leaching, water content, soil temperature), deadwood, stand structure, vegetation regrowth, abundance of selected fauna (moths, beetles, mammals), UAV-based remote sensing (stand structure, spatial overview), and photo monitoring (succession). Thus, the multitude of collected data allows not only for detailed analyses of these observables separately, but also considering their interaction for a more multidisciplinary view on forest recovery after a wildfire.
