Airborne Laser Scanning (ALS) has implied a disruptive transformation of how data are gathered for forest management planning in Nordic countries. We show in this study that the accuracy of ALS predictions of growing stock volume can be maintained and even improved over...

3D information extracted by image matching of aerial images, so called image-based point clouds, have been found to provide accurate vegetation height measurements. This has led to an increased interest from the vegetation mapping community, since aerial images are an a...

As we are entering an era of increased supply of remote sensing data, we believe that dataassimilation that combines growth forecasts of previous estimates with new observations of thecurrent state has a large potential for keeping forest stand registers up to date (Ehl...

Effective management of poplar plantations for high yield production would be facilitated by the availability of improved equations for predicting the taper and volume of poplar stems. Therefore, this thesis is based upon a polynomial stem taper equation and two volume ...

Nitrogen (N) fertilisation increases tree production in boreal forests, but it is poorly known how long the fertiliser effect will remain after the end of the fertilisation. We studied a Scots pine stand during 17 years of annual fertilisation with N and other nutrients...

During outbreak periods, the European spruce bark beetle and the North American mountain pine beetle are able to kill millions of coniferous trees. Throughout the 20th century, six outbreaks have occurred in Sweden and four in British Columbia, with about 20-year interv...

Barkning är en klassisk metod för att motverka insektsangrepp i färskt barrvirke och på stående skog som ligger i anslutning till platser där sådant virke lagras. Förr barkades virke i stor omfattning då det lagrades i skogen under sommarhalvåret. Idag körs virket omgåe...

Background Climate change is influenced by a number of driving forces, due to human needs and activities, including people’s attitudes to forest and forestry. Thus, the combined society-forest system is under continuous change and the mutual dependency is large and mult...
