Modelling above-ground biomass stock over Norway using national forest inventory data with ArcticDEM and Sentinel-2 data
Space-borne imagery Stereogrammetry Boreal forest structure Biomass mapping Open data
2024/1/22
Boreal forests constitute a large portion of the global forest area, yet they are undersampled through field surveys, and only a few remotely sensed data sources provide structural information wall-to...
The Deep Borehole Demonstration Center has signed a memorandum of understanding (MoU) with Norsk Kjernekraft to collaborate on demonstration of deep borehole disposal in Norway. The centre - launched ...

The research reported focuses on the multi-causal landslide risk in Sandnes (Norway) in connection with the climate change, the use of the land and the geological/geotechnical properties of the urban ...
Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach
base-age invariant approach Chapman-Richards function global parameters tree-specific parameters iterative nested regression National Forest Inventory
2017/6/26
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
Importance of the first thinning in young mixed Norway spruce and European beech stands
pre-commercial thinning diameter distribution h/d ratio skewness kurtosis
2018/3/6
Experimental results from the first thinning in mixed stands are not broadly experienced by forestry practice. To extend
the experience with the thinning of a mixed stand, we studied thinned and unth...
Changes in the nutrition and health status of young Norway spruce stands in the Krkonoše Mts. in a 17-year period
mountain forest height increment defoliation nutrients stress elements nutrient ratio
2018/3/6
For 17 Norway spruce stands located in the Krkonoše Mts. in the Czech Republic a long-term assessment of defoliation,
height increment, foliage concentration of nutrients (N, P, Ca, K, Mg) and s...
Multivariate analysis for assessment of the tree populations based on dendrometric data with an example of similarity among Norway spruce subpopulations
dendrometry hierarchical classification ordination Picea abies
2018/3/6
The new method for evaluation of tree populations presented here is based on a correlation analysis within a set of
dendrometric variables. The correlation analysis is carried out for each population...
Production and soil restoration effect of pioneer tree species in a region of allochthonous Norway spruce dieback
forest transformation regeneration methods birch aspen wood production soil chemistry
2017/4/6
The paper analyses the growth, structure, production and soil chemistry of different tree species stands 20 years after allochthonous spruce dieback. The experiment was carried out at lower altitudes ...
Below-canopy and topsoil temperatures in young Norway spruce and Carpathian birch stands compared to gaps in the mountains
air soil below-canopy climate microclimate stand environment
2016/11/11
Reduced air pollution load has allowed to use commercially oriented forestry in the Central European mountains since the 1990s. The goal is, however, to restore species- and age-diversified stable sta...
Effect of Bio-Algeen preparation on growth and mycorrhizal characteristics of Norway spruce seedlings
Ascophyllum nodosum ectomycorrhiza nurseries Picea abies seaweed
2016/7/6
In this paper, the effect of the Bio-Algeen® product (bio-alginate from the seaweed Ascophyllum nodosum (Linnaeus) Le Jolis) was evaluated in relation to basic mycorrhizal and growth characterist...
Fine root development and mycorrhization in Norway spruce stands one year after fertilization with potassium sulphate and wood ash
forest fertilization fine root ectomycorrhizal fungi
2016/1/29
We compared the effects of forest fertilization with wood ash and potassium (K) sulphate on growth and mycorrhizal colonization of fine roots and on other soil microorganisms in Norway spruce (Picea a...
3-DIMENSIONAL GEOLOGICAL MAPPING AND MODELING ACTIVITIES AT THE GEOLOGICAL SURVEY OF NORWAY
3D geology Geometric modelling Boreholes
2015/11/3
Geology and all geological structures are three-dimensional in space. Geology can be easily shown as four-dimensional when time is considered. Therefore GIS, databases, and 3D visualization software a...
