Prediction and model-assisted estimation of diameter distributions using Norwegian national forest inventory and airborne laser scanning data
(Peer reviewed; Journal article, 2021-04-07)Diameter at breast height (DBH) distributions offer valuable information for operational and strategic forest management decisions. We predicted DBH distributions using Norwegian national forest inventory and airborne laser ... -
Prediction of butt rot volume in Norway spruce forest stands using harvester, remotely sensed and environmental data
(Peer reviewed; Journal article, 2021-12-25)Butt rot (BR) damage of a tree results from a decay caused by a pathogenic fungus. BR damages associated with Norway spruce (Picea abies [L.] Karst.) account for considerable economic losses in timber production across the ... -
Prediction of forest canopy fuel parameters in managed boreal forests using multispectral and unispectral airborne laser scanning data and aerial images
(Peer reviewed; Journal article, 2020-09-08)This study evaluated the suitability of different airborne laser scanning (ALS) datasets for the prediction of forest canopy fuel parameters in managed boreal forests in Finland. The ALS data alternatives were leaf-off and ... -

Quality variation in comminuted forest fuels delivered during the winter in north Sweden
(Peer reviewed; Journal article, 2020-10-17)Swedish legislation stipulates the precision required for estimates of parameters used to determine the value of various forest fuels. The net energy value of fuel, as it is received, is often used to set the trade price. ... -
Quantifying regional surface energy responses to forest structural change in Nordic Fennoscandia
(Peer reviewed; Journal article, 2020-07-16)In a climate model, surface energy and water fluxes of the vegetated ecosystem largely depend on important structural attributes like leaf area index and canopy height. For forests, management can greatly alter these ... -
Radiative forcing bias of simulated surface albedo modifications linked to forest cover changes at northern latitudes
(Journal article; Peer reviewed, 2015-04-15) -
Raman micro-spectroscopy of two types of acetylated Norway spruce wood at controlled relative humidity
(Peer reviewed; Journal article, 2022-09-06)Water is a key element for wood performance, as water molecules interact with the wood structure and affect important material characteristics such as mechanical properties and durability. Understanding wood-water interactions ... -
Re-evaluation of the genus Englerodendron (Leguminosae–Detarioideae), including Isomacrolobium and Pseudomacrolobium
(Peer reviewed; Journal article, 2019-10-11)On the basis of a new phylogeny of the Detarioideae, with a particular focus on Englerodendron Harms, Anthonotha P.Beauv. and related genera, the possible options for delimiting monophyletic genera are discussed. As a ... -
Recent strengthening of snow and ice albedo feedback driven by Antarctic sea-ice loss
(Peer reviewed; Journal article, 2021-10-28)The decline of the Arctic cryosphere during recent decades has lowered the region’s surface albedo, reducing its ability to reflect solar radiation back to space. It is not clear what role the Antarctic cryosphere plays ... -
Reconstructing past fossil-fuel CO2 concentrations using tree rings and radiocarbon in the urban area of Medellín, Colombia
(Peer reviewed; Journal article, 2022-04-25)To meet international and national commitments to decrease emissions of fossil fuels, cities around the world must obtain information on their historical levels of emissions, identifying hotspots that require special ... -
Red List updates and the robustness of sites selected for conservation of red-listed species
(Journal article; Peer reviewed, 2018)The long-term success of sites selected for species conservation depends on the persistence of target species. Red List species or threatened species lists are frequently defined as target species, but when Red Lists are ... -
Rein som beitedyr i kystlynghei
(NIBIO Rapport;3(40) 2017, Research report, 2017-03-02)Øygruppen Tarva har siden 2010 hatt status som Utvalgt kulturlandskap, hovedsakelig begrunnet i de store arealressursene med kystlynghei i god hevd. Kystlynghei er en trua naturtype beskyttet av naturmangfoldloven som ... -
