The raw materials of forest chips are small-diameter trees from thinning fellings and logging residues and stumps from final fellings. The harvesting potential consists of biomass that would be available after technical and economic constraints. Such constraints include, e.g., minimum removal of energywood per hectare, site fertility and recovery rate. Note that the techno-economic potential is usually higher than the actual availability, which depends on forest owners’ willingness to sell and competitive situation. The harvesting potentials were estimated using the sample plots of the 12th national forest inventory (NFI12) measured in the years 2014–2018. First, a large number of sound and sustainable management schedules for five consecutive ten-year periods were simulated for each sample plot using a large-scale Finnish forest planning system known as MELA (Siitonen et al. 1996; Hirvelä et al. 2017; http://mela2.metla.fi/mela/tupa/index-en.php). MELA simulations consisted of natural processes and human actions. The ingrowth, growth, and mortality of trees were predicted based on a set of distance-independent tree-level statistical models (e.g. Hynynen et al. 2002) included in MELA and the simulation of the stand (sample plot)-level management actions was based on the current Finnish silvicultural guidelines (Äijälä et al. 2014) and the guidelines for harvesting of energy wood (Koistinen et al. 2016). Future potentials were assumed to materialize when the industrial roundwood fellings followed the level of maximum sustained yield (79 mill. m3 in this calculation). The maximum sustained yield was defined such that the net present value calculated with a 4% discount rate was maximized subject to non-declining periodic industrial roundwood and energy wood removals and net incomes, and subject to the saw log removal remaining at least at the level of the first period. There were no constraints concerning tree species selection, cutting methods, age classes, or the growth/drain ratio in order to efficiently utilize the dynamics of forest structure. The potential for energywood from thinnings was calculated separately for all the energywood from thinnings (Stemwood for energy from thinnings) and for material that does not fulfill the size-requirements for pulpwood (Stemwood for energy from thinnings (smaller than pulpwood-sized trees)). Note that the decision whether pulpwood-sized thinning wood is directed to energy or industrial use, is based on the optimisation by MELA. The minimum top diameter of pulpwood in the calculation was 6.3 cm for pine (Pinus sylvestris) and 6.5 cm for spruce (Picea abies) and broadleaved species (mainly Betula pendula, B. pubescens, Populus tremula, Alnus incana, A. glutinosa and Salix spp.). The minimum length of a pulpwood log was assumed at 2.0 m. Energywood could be harvested as whole trees or as delimbed. The dry-matter loss in the supply chain was assumed at 5%. The potentials for logging residues and stumps were calculated as follows: The crown biomass removals of clear fellings were obtained from MELA. According to harvesting guidelines for energywood (Koistinen et al. 2016) mineral soils classified as sub-xeric (or weaker) and peatlands with corresponding low nutrient levels were left out from the potentials. Next, technical recovery rates were applied (70% for logging residues and 82-84% for stumps) (Koistinen et al. 2016; Muinonen et al. 2013). Finally, a dry-matter loss of 20% and 5% was assumed for residues and stumps, respectively. The techno-economical harvesting potentials were first calculated for nineteen Finnish regions and then distributed on a raster grid at 1 km × 1 km resolution by weighting with Multi-Source NFI biomasses as described by Anttila et al. (2018). The potentials represent time period 2026-2035 and are presented as average annual potentials in solid cubic metres over bark.

The Arctic SDI Geoportal provides access to geospatial data and services available via the Arctic SDI to support and facilitate monitoring, management and decision making, and support sustainable development in the Arctic. Specifically, the Arctic SDI Geoportal facilitates the discovery, visualization, evaluation, download and integration of geographic data from a variety of sources for the Arctic. The Arctic SDI Geoportal is the result of cooperative efforts between the National Mapping Agencies (NMAs) of the eight Arctic Council Member countries - Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. The Arctic SDI Geoportal includes reference data (such as the Arctic SDI topographic basemap or Pan-Arctic Digital Elevation Model) and thematic data from various sources. Thematic data section includes themes such as oceans, climatology and geoscientific information. Most of the data covers the Arctic or the involved Arctic countries, but new data sources with a smaller or larger geographical extent may be accepted. The Geoportal allows searching placenames via a circumpolar gazetteer, and embedding interactive maps to any website. Some of the features require registration.

Agricultural land is the area of arable land (AL), permanent grassland (PG) and permanent crops (PC). Arable land is land cultivated for crop production or fallow land available for cultivation. Permanent grassland Permanent grassland is the area used to grow grasses or other herbaceous forage crops that have been on the same site for more than 5 years, either by self-regulation or by sowing. Permanent grassland may be arable land or natural pasture and meadow. Permanent grassland may not contain more than 50 trees per hectare in a scattered pattern. Trees are considered to be single- or multi-trunked trees and woody shrubs of at least four metres in height. Shrubs of all sizes are also considered as trees. Trees in windbreaks are not counted in the tree count. Deciduous bushes suitable for feeding farm animals and deciduous tree seedlings may be grown on the area if they cover less than half of the area of the eligible plot. More than half (50 %) of the area of the plot must be grass and forage. This requirement also applies to parcels of permanent grassland with trees or deciduous shrubs or both. Permanent crops Permanent crops are crops which are not part of the crop rotation, which are grown for at least 5 years and which produce a repeated harvest. These include fruit trees, berry bushes and ornamental plants. More information: https://www.ruokavirasto.fi/globalassets/tuet/maatalous/oppaat/hakuoppaat/peltotukiopas/maatalousmaa-2024.pdf

The Superficial deposits of Finland 1:200 000 (sediment polygons) contains data produced from the whole of Finland during the period 2002-2009. The data set can be used in regional planning, in military defence, in soil mapping (EU) and in joint mapping projects in various areas. The mapping scale has been 1:50 000-1:200 000. In compiling the medium-scale data set, generalised 1:20 000, 1:50 000 and 1:100 000 superficial deposits maps have been used and a new map product at a scale of 1:200 000 that is based on interpretation and field mapping. The minimum size of the sediment polygons is about six hectares. Exceptions are glaciofluvial, marginal till and hummocky moraine deposits, which are presented in the data set as areas with a surface area greater than two hectares. The blanketing peat overburden has been described in the new map product as a peat-covered area (0-0.3 m of peat), thin peat (0.3-0.6 m of peat) and thick peat (over 0.6 m of peat). Peat-covered areas, stone fields and uncovered bedrock areas have been added to the new production map by generalising the corresponding polygons in the terrain database of the National Land Survey of Finland (NLS). In connection with the generation of new production map, field observations have been gathered on the overburden thickness and the stratigraphic sequence at a depth of one metre as well as on rock exposures. Coordinate reference system of the Superficial deposits of Finland 1:200 000 (sediment polygons) was transformed in March 2013. The transformation from Finnish National Grid Coordinate System (Kartastokoordinaattijärjestelmä, KKJ) Uniform Coordinate Frame to ETRS-TM35FIN projection was done by using the three-dimensional transformation in accordance with the recommendations for the public administration JHS154.
