—A central characteristic of soil in the arctic is its load bearing capacity since that property influences forest harvester mobility, flooding dynamics and infrastructure potential. The hydraulic conductivity has the greatest dynamical influence to bearing capacity and hence is essential to measure or estimate. In addition, the arctic soil type information(More)
Water permeability is a key concept when estimating load bearing capacity, mobility and infrastructure potential of a terrain. Northern sub-arctic areas have rather similar dominant soil types and thus prediction methods successful at Northern Finland may generalize to other arctic areas. In this paper we have predicted water permeability using publicly(More)
Growth decline of Scots pine (Pinus sylvestris L.) on reforestation sites with fine-textured soils are suggested to be due to periodic soil wetness. In this study, Scots pine seedlings were exposed to waterlogging in fine-textured till soil in growth chambers. The treatments started 5 weeks after germination and lasted either for 3 or 8.5 weeks. Three weeks(More)
Three methods to estimate the presence of ground surface stones from publicly available Airborne Laser Scanning (ALS) point clouds are presented. The first method approximates the local curvature by local linear multi-scale fitting, and the second method uses Discrete-Differential Gaussian curvature based on the ground surface triangulation. The third(More)

Peatlands are important ecosystems in the cool and humid boreal climatic zone covering over one third of the landscape in northern Finland. Classification of mire site types, based on soil nutrient and water regimes driven plant communities, provides primary information for peatland inventories and ecological studies. In this study, the treeless pristine(More)
