An operational UAV-based approach for stand-level assessment of soil disturbance after forest harvesting
(Journal article; Peer reviewed, 2018-01-16)The effectiveness of generating virtual transects on unmanned aerial vehicle-derived orthomosaics was evaluated in estimating the extent of soil disturbance by severity class. Combinations of 4 transect lengths (5–50 m) ... -
Contrasting impact of whole-tree-harvesting on chemical quality of plant foliage in coastal versus inland forest
(Journal article; Peer reviewed, 2016-02-09)Whole-tree-harvesting (WTH) is gaining support as a means to obtain more bioenergy from forests. One aspect that is scarcely addressed is its impact on the chemical quality of post-harvest plant growth, which may initiate ... -
Epigenetic memory effects in Norway spruce: are they present after the age of two years?
(Peer reviewed; Journal article, 2022-03-07)Short-term trials on cultivated soil were planted with families of Norway spruce that had shown epigenetic memory effects in early tests up to age two years. Measurements and assessments were made of phenology traits, tree ... -
High-pruning of European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.): work efficiency for target pruning as a function of tree species, pruning height, branch characteristics, pole saw type and operator
(Journal article; Peer reviewed, 2018-02-27)The objective of this study was to establish an operational model of productive work time per tree (work efficiency) for high-pruning of young European beech and pedunculate oak depending on tree species, pruning height, ... -
Identifying old Norway spruce and Scots pine trees by morphological traits and site characteristics
(Peer reviewed; Journal article, 2021-11-05)Old trees are important for biodiversity, and the process of their identification is a critical process in their conservation. However, determining the tree age by core extraction, ring counts, and eventually, cross-dating ... -
Postharvest needle retention in Norway spruce Christmas trees
(Peer reviewed; Journal article, 2020-07-22)Norway spruce (Picea abies) is a widely used Christmas tree species in the Nordic countries. Postharvest needle retention is an important characteristic for Christmas trees and compared to many fir (Abies) species, Norway ... -
Remote sensing and forest inventories in Nordic countries - roadmap for the future
(Journal article; Peer reviewed, 2018-01-18)The Nordic countries have long traditions in forest inventory and remote sensing (RS). In sample-based national forest inventories (NFIs), utilization of aerial photographs started during the 1960s, satellite images during ... -
Root frost tolerance, seasonal variation in root growth, and field performance of one-year-old Russian larch seedlings with simulated root freezing damages
(Peer reviewed; Journal article, 2023-05-08)Planting healthy seedlings with optimal growth potential is essential for proper growth and survival in forest regeneration. Assessing the seedling quality prior to planting is therefore important. In this Icelandic study, ... -
Short-term effects of hardened wood ash and nitrogen fertilisation on understory vegetation in a Norway spruce forest in south-east Norway
(Peer reviewed; Journal article, 2022-07-26)In a fertiliser experiment in a Norway spruce forest in SE Norway, four treatments were applied in a block design with three replicates per treatment. Treatments included 3 t wood ash ha−1 (Ash), 150 kg nitrogen ha−1 (N), ... -
Short-term effects of whole-tree harvesting on understory plant species diversity and cover in two Norway spruce sites in southern Norway
(Journal article; Peer reviewed, 2016-04-06)Effects of clear-cut harvesting on ground vegetation plant species diversity and their cover are investigated at two Norway spruce sites in southern Norway, differing in climate and topography. Experimental plots at these ... -
A stand-level growth and yield model for thinned and unthinned managed Norway spruce forests in Norway
(Peer reviewed; Journal article, 2020-06-05)A new stand-level growth and yield model, consisting of component equations for stand volume, basal area, survival, and dominant stand height, was developed from a dataset of long-term trials for managed thinned and unthinned ... -
Stand-level growth models for long-term projections of the main species groups in Norway
(Peer reviewed; Journal article, 2022-04-07)Stand-level growth and yield models are important tools that support forest managers and policymakers. We used recent data from the Norwegian National Forest Inventory to develop stand-level models, with components for ... -
Use of UAV photogrammetric data in forest genetic trials: measuring tree height, growth, and phenology in Norway spruce (Picea abies L. Karst.)

Wild boar rooting in a northern coniferous forest - minor silviculture impact
(Journal article; Peer reviewed, 2013-12-05)European wild boar (Sus scrofa) is expanding northwards beyond its preferred habitat of broadleaved forests. We studied wild boar habitat use in a northern coniferous forest, and noted whether their rooting damaged roots, ...
