Boreal tree species change as a climate mitigation strategy: impact on ecosystem C and N stocks and soil nutrient levels
Kjønaas, O. Janne; Barcena, Teresa G.; Hylen, Gro; Nordbakken, Jørn-Frode; Økland, Tonje (Peer reviewed; Journal article, 2021-11-24)To increase the annual uptake of CO2 as well as the long-term storage of carbon (C) in forests, the Norwegian government consider large-scale replacements of native, deciduous forests with faster-growing species like Norway ... -
Climate change drives substantial decline of understorey species richness and abundance in Norway spruce forests during 32 years of vegetation monitoring
Økland, Tonje; Halvorsen, Rune; Lange, Holger; Nordbakken, Jørn-Frode; Clarke, Nicholas (Peer reviewed; Journal article, 2023-05-31)Questions Observations in permanent forest vegetation plots in Norway and elsewhere indicate that complex changes have taken place over the period 1988–2020. These observations are summarised in the “climate-induced ... -
Shift in tree species changes the belowground biota of boreal forests
Mundra, Sunil; Kauserud, Håvard; Økland, Tonje; Nordbakken, Jørn-Frode; Ransedokken, Yngvild Eidissen; Kjønaas, O. Janne (Peer reviewed; Journal article, 2022-03-20)The replacement of native birch with Norway spruce has been initiated in Norway to increase long-term carbon storage in forests. However, there is limited knowledge on the impacts that aboveground changes will have on the ... -
Short-term effects of hardened wood ash and nitrogen fertilisation on understory vegetation in a Norway spruce forest in south-east Norway
Økland, Tonje; Nordbakken, Jørn-Frode; Clarke, Nicholas; Hanssen, Kjersti Holt (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
Økland, Tonje; Nordbakken, Jørn-Frode; Lange, Holger; Røsberg, Ingvald; Clarke, Nicholas (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 ...
