Abstract

This case study is made on assignment of Södra, region Öst, as a part of a campaign promoting more active management of the oak forests in the region. Hardwood trees of good quality, especially oak, has a high value due to that the sawn material is highly estimated by the market. It is important that the Swedish oak forests are managed in a proper way in order to meet the future demand. Södra has therefore decided to increase the focus on oak in the Kalmar region and they would like to find out if continues cover forestry (CCF) under certain conditions can be an appropriate management model. The motive is to make use of the existing oak forests more efficient, not just considering well managed forests but also the more neglected oak forests, on poorer soils. Thus, the objective for this study is to examine if CCF is appropriate method in the three stand types; broadleaved mixtures oak forest, oak islet, and oak/spruce forest. Existing management models were surveyed in the literature. CCF-cuttings made by Södra were also studied. After that three chosen management methods where applied theoretically in field in three stands. 6-7 sample plots per hectare where out haphazard in the stands. On the sample plots stand data where measured and the management methods where simulated. The collected data from this simulation where put together and afterwards used in the compassion and analysis. Without the subsidies that the board of forestry gives to hardwood management CCF where the best alternative, except from oak/spruce forest that had better growth. In this stand the standard method gave slightly better results. When the same comparison but with the subsidies that the board of forestry gives where made the standard method gave the best result in all stands. The numbers of future stems where lower though than what the standard method aim at, which can complicate for the method. One critical factor if CCF is applied is the natural regeneration. The regeneration was scarce in the studied stands and. lack of regeneration can in the long term can jeopardize a proper stand development.
