Spatial overlap between environmental policy instruments and areas of high conservation value in forest.
Autor: Anne Sverdrup-Thygeson, Gunnhild Søgaard, Graciela M Rusch, David N Barton
Publikováno v: PLoS ONE, Vol 9, Iss 12, p e115001 (2014)
In order to safeguard biodiversity in forest we need to know how forest policy instruments work. Here we use a nationwide network of 9400 plots in productive forest to analyze to what extent large-scale policy instruments, individually and together,

Evaluating the terrestrial carbon dioxide removal potential of improved forest management and accelerated forest conversion in Norway
Autor: Aksel Granhus, Ryan M. Bright, Helmer Belbo, Micky Allen, Olaug J Kjønaas, Rasmus Astrup, Gunnhild Søgaard, Stephanie Eisner, Lise Dalsgaard, Clara Antón-Fernández
Publikováno v: Global Change Biology
As a carbon dioxide removal measure, the Norwegian government is currently considering a policy of large-scale planting of spruce (Picea abies (L) H. Karst) on lands in various states of natural transition to a forest dominated by deciduous broadleav

Evaluating the terrestrial carbon dioxide removal (tCDR) potential of large-scale aff-/reforestation and improved forest management in Norway
Autor: Micky Allen, Clara Antón-Fernández, Stephanie Eisner, Lise Dalsgaard, Gunnhild Søgaard, Aksel Granhus, Ryan M. Bright, Rasmus Astrup
As a carbon dioxide removal measure, the Norwegian government is currently considering a policy of large-scale planting of spruce (Picea abies (L) H. Karst) on non-forested lands (i.e., aff-/reforestation) and secondary forested lands dominated by ea

Tree, stand and site characteristics affecting the occurrence of lammas growth and multiple tops in field-grown Norway spruce
Autor: Harald Kvaalen, Marek Metslaid, Gunnhild Søgaard, Aksel Granhus
Publikováno v: New Forests. 50:291-305
In the Nordic-Baltic region, there has been a growing concern about an increasing occurrence of multiple tops in young stands of Norway spruce. There is however a lack of documentation on the amount of such damages, and the causal agents involved. In

Harvesting of logging residues affects diameter growth and pine weevil attacks on Norway spruce seedlings
Autor: Kjersti Holt Hanssen, Gunnhild Søgaard, Inger Sundheim Fløistad, Aksel Granhus
Publikováno v: Scandinavian Journal of Forest Research. 33:40-49
Removal of logging residues causes significant nutrient losses from the harvesting site. Furthermore, collection of residues into piles could lead to small-scale differences in establishment conditions for seedlings. We studied the effects of stem-on

Effect of frost nights and day and night temperature during dormancy induction on frost hardiness, tolerance to cold storage and bud burst in seedlings of Norway spruce
Autor: Øystein Johnsen, Aksel Granhus, Gunnhild Søgaard
Publikováno v: Trees. 23:1295-1307
For trees, the ability to obtain and maintain sufficient levels of frost hardiness in late autumn, winter and spring is crucial. We report that temperatures during dormancy induction influence bud set, frost hardiness, tolerance to cold storage, timi

Bud burst timing in Picea abies seedlings as affected by temperature during dormancy induction and mild spells during chilling
Autor: Inger Sundheim Fløistad, Gunnhild Søgaard, Aksel Granhus
Publikováno v: Tree Physiology. 29:497-503
In trees adapted to cold climates, conditions during autumn and winter may influence the subsequent timing of bud burst and hence tree survival during early spring frosts. We tested the effects of two temperatures during dormancy induction and mild s

Secondary buds in Scots pine trees infested with Gremmeniella abietina
Autor: Gunnhild Søgaard, Halvor Solheim, Øystein Johnsen
Publikováno v: Trees. 21:191-199
In winter 2000–2001, there was a serious outbreak of Gremmeniella abietina Morelet in southeastern Norway. During the outbreak, we noted that injured Scots pine trees (Pinus sylvestris L.) developed secondary buds in response to the fungus attack,
