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)
Peatlands have traditionally been exploited in forestry and agriculture over the boreal region, yet they also provide substantial source of fuel production. The large-scale exploitation of peatlands has raised a concern about the diversity of mire plant communities. We studied composition of mire plant communities along soil nutrient potential and water(More)
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)
Presence of ground surface stones is one indicator of economically important landmass deposits in the Arctic. The other indicator is a geomorphological category of the area. This work shows that ground stoniness can be automatically predicted with practical accuracy. Northern forests have less biomass and foliage, thus direct analysis of stoniness is(More)
Image edge detection or extraction is always a research hotspot in remote sensing image processing. Up to now, there are many methods have been used in this area, such as threshold segmentation, edge detection operators, region growing method and so on. But threshold segmentation cannot meet the accuracy we needed and edge detection operators are always(More)
The northern boreal forests in Fennoscandia have been managed for decades using clear-cut harvesting and subsequent mechanical site preparation (MSP). MSP is intended to reduce competing vegetation, improve soil temperature and water conditions as well as mobilize nutrients for the use by outplanted seedlings. The use of heavy machinery, particularly(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)
