Abstract
Ungskogpleie anses å være blant de viktigste behandlingsmessige tiltak man kan gjennomføre i skogen og med solid tradisjon i nordisk skogbruk. I denne artikkelen ser vi litt nærmere på hvordan ungskogpleie bidrar til å påvirke skogens langsiktige utvikling. Skogforskningen har siden 1950-tallet drevet systematiske undersøkelser på effektene av ungskogpleie.

Abstract
Changed land use practice is one of the greatest threats to biodiversity. Abandonment and agricultural intensification are regarded as the most frequent land use changes in semi-natural habitats in Norway. The aim of this project was to explore how colour infrared (CIR) aerial photographs can be used for monitoring and quantifying of encroachment and intensification in semi-natural grassland in Norway.
Abstract
This study is a part of a larger project designed to find out the causes of top dieback symptoms in Norway spruce in SE Norway. Because sapwood tracheids constitute a water transport system while parenchyma serves as a reserve tissue (Sellin, 1991), the separation and quantification of the sapwood and heartwood may contribute to understanding of the healthy tree functioning. As the extent of sapwood is related to tree vitality, it reflects the tree growth, health and effect of environmental factors (Sandberg & Sterley, 2009). Therefore, the sapwood cross-sectional area is widely used as a biometric parameter indicating the tree vitality, although its estimation and evaluation is prone to scaling errors....

Abstract
Use of participatory stakeholder engagement processes could be important to reduce the risk of potential conflicts in managing contaminated sites. Most stakeholder engagement techniques are qualitative in nature and require experienced facilitators. This study proposes a multicriteria involvement process to enhance transparency and stakeholder participation and applies it to a contaminated sediment management case study for Bergen Harbor, Norway. The suggested multicriteria involvement process builds on the quantitative principles of multicriteria decision analysis and also incorporates group interaction and learning through qualitative participatory methods. Three different advisory groups consisting of local residents, local stakeholders, and nonresident sediment experts were invited to participate in a stakeholder engagement process to provide consensual comparative advice on sediment remediation alternatives. In order for stakeholders or residents to be able to embrace a complex decision such as selection of remediation alternatives, the involvement process with lateral learning, combined with multicriteria decision analysis providing structure, robustness and transparent documentation was preferable. In addition, a multicriteria involvement process resulted in consistent ranking of remediation alternatives across residents, stakeholder, and experts, relative to individual intuitive ranking without the multicriteria involvement process.
