1. Effects of forest management on greenhouse gas fluxes in a boreal forest
Sammanfattning : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.

2. Boreal vegetation responses to forestry as reflected in field trial and survey data
Sammanfattning : This thesis had two objectives: the first objective was to evaluate the response of forest ground vegetation to selected forestry operations, i.e. cutting of different intensities and scarification; the second objective was to compare the use of survey data in vegetation research with that of more traditional research using field trials - i.e. LÄS MER
3. Individual-tree-selection in uneven-sized Norway spruce stands in southern Sweden : Developments of tools for simulation and optimization
Sammanfattning : Individual-tree-selection (ITS) is a continuous cover forestry method that aims to utilize the uneven-sized stand structure through optimized individual tree selections. ITS is an interesting management alternative to rotation forestry in terms of production of multiple benefits and forest owner profitability. LÄS MER
4. Clear-cutting - The most discussed logging method in Swedish forest history
Sammanfattning : Clear-cutting has been applied in Sweden for nearly 200 years. To understand the history of this method, the ongoing discussion about logging methods, and the current debate about clear-cutting, an analysis of the forestry history is needed. LÄS MER
5. Chemical composition and machinability of selected wood species from Mozambique
Sammanfattning : The objectives of the current work were to carry out a survey on timber sector in Mozambique and to determine chemical, calorific and machinability features of selected species. Mozambican timber sector was described as dominated by selective harvesting practices on a few hardwood species out of 118 species growing in the forest with potential for industrial timber. LÄS MER
