Publications

NIBIOs employees contribute to several hundred scientific articles and research reports every year. You can browse or search in our collection which contains references and links to these publications as well as other research and dissemination activities. The collection is continously updated with new and historical material.

Abstract

Through the report “Green Knowledge 2024”, the Norwegian Institute of Bioeconomy Research (NIBIO) presents a small selection of our contributions to sustainable solutions for agriculture, forestry, management, and food production. Through our work in Norway and internationally, we are dedicated to contributing to sustainable value creation and forward-looking management of our shared biological resources.

Abstract

• There is still a lack of knowledge on growth and yield (G&Y) in continuous cover forestry (CCF). Most published studies are on the selection system with Norway spruce. • Published comparisons of the selection system with rotation forestry (RF) show contrasting results. Generally, there seems to be a trend toward faster stand growth in RF. • However, there are many uncertainties due to several confounding factors, such as stand-density effects, site-quality classifcation, and/or growth models used. Most studies do not properly account for all these factors, making it diffcult to generalise their results. • The optimal stand density trade off for the selection system between stand growth and recruitment should be better investigated. Preliminary results show this could strongly affect stand growth. • There is even less knowledge related to G&Y during conversion, a potential bottleneck for full implementation of CCF in the region.

Abstract

• Overall forest management objectives and stand properties set the requirements and possibilities for harvesting in continuous cover forestry (CCF). • Harvester and forwarder operators play a key role in successful CCF harvesting, as both productivity and quality of work are essential factors in harvesting operations. • Optimal stand conditions improve work productivity on selection harvesting sites; harvested stem volume correlates well with work productivity in cutting, and density of remaining trees does not signifcantly reduce work productivity in forwarding. • Carefully executed group cutting and shelterwood harvesting can reduce the number of damaged remaining trees, which is benefcial for future tree generations. • Research-based information is needed about work productivity in harvesting, damage caused by harvesting, and optimisation of strip road and forest road networks for CCF.
