Laserdata i skogsbruket : - och möjliga tillämpningar för privata skogsägare
Data retrieved from airborne laser scanning represents a new source of forest data. Today, the technology has matured so that it can function in an operational environment. The aim of this study was to compile areas of application of laserdata in forestry. Moreover to analyze costs and accessibility of laserdata. The goal was to provide private forest owners information to support assessments of possible benefits of laserdata.
Bioenergy from the forest ? a source of conflict between forestry and nature conservation? : an analysis of key actor?s positions in Sweden
Bioenergy from the forest has been heavily debated in Sweden for several decades due to the interest of society to decrease dependence upon fossil fuels and limit the effects of climate change. The actual use of bioenergy from the forest has shifted over the years but increased during the last decades. Private actors within forest and nature conservation sectors play an important role for the development of bioenergy from the forest as well as for the debate and the implementation of political goals. Forestry in Sweden is characterised by ?freedom under responsibility? for private actors and the perspective of governance is valuable for studying actors and discourses.
Skogspolitik i Sverige
For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.
Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.
The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..
Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen
The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.
Planering för friluftsliv, biologisk mångfald och skogsbruk i skogsmiljö
Vallentuna municipality in Stockholm County, is planning to develop a management plan for a forest area owned by the municipality. The property is an urban forest and the hiking trail Roslagsleden runs through it. Hence the municipality intends to take extra care of the outdoor recreation interests, as well as forest biodiversity, but at the same time use the area for forestry. This study discusses how these three interests, recreation, biodiversity and forestry, differ in their views of how a forest should be managed, where they disagree and how they can coexist in the management of this area. In this study, a vegetation mapping of the area and an assessment of the forest?s conservation values was carried out.
En jämförelse av skogsmarksprisets utveckling mellan Sverige, Danmark, Norge, Finland, Estland och Lettland
During the twenty-first century the price of forest land in Sweden has increased heavily. Buying forest land has become more common and the stakeholders have grown in number.
The countries around Sweden have through the globalization become connected in the market of round wood and wood products. The price of forest land and round wood are also close connected.
The goal with this report is to make a comparison of forest land prices between Sweden, Denmark, Norway, Finland, Estonia and Latvia and to see how the prices have developed in the period 2000-2011. The prime factor in the comparison, except the direct price difference between the countries, is the round wood prices. The round wood prices give information about the economic situation in the countries and play an important role in the return on the forest land.
The prices of forest land shifts heavily between the countries.

Aspekter på flyttkostnader, fastighetsbildning och fastighetstorlekar :
This master thesis has three purposes. The first purpose is to give a theoretical background of how to divide up forest estates and to study how the legal system for these matters works.
A literature study has been carried out to give the background and a theoretical model has been made for analysing the law cases. The first purpose also partly touched the decision process in dividing up forest estates from point of view of the law of land parcelling (FBL), point of view.
The second purpose is to examine effects of a change of production requirements in 3 cap.7 § FBL as regards dividing up forest estates of private forest owners.
Stamprofiler : en jämförelse mellan två olika apteringslistor
This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU.
The aim of the work was to compare two different pricelists with the actual output from a harvester. The results have also been compared with a volume estimate of standing trees done by the Swedish Forest Agency and the ?true? value registered by the Wood Measurement Association.
The study confirms that the output calculated by the computer on the harvester is more reliable than the volume of standing trees estimated by Swedish Forest Agency.

Managing urban development : A case study of urban forest?s sense ofplace in Hammarbyskogen, Stockholm
Due to the growing population in Stockholm, some of the urban green areas are beingsubjected to exploitation. Hammarbyskogen is an urban forest in the south of Stockholm andis an example of a green area that is planned to be transformed into an urban environment.This paper investigates key qualities and values of an urban forest of Hammarbyskogenvalued by local inhabitants of the neighbourhoods of Hammarbyhöjden and Björkhagen in thesouth of Stockholm. In addition to that, the study seeks to investigate people?s perception ofthe planned development of the forest as well as investigate how these perceptions andqualities are being incorporated into the process of neighbourhood development.Using text analysis, interviews and discussion forums, findings have been made showing thatthe local inhabitants value the urban forest mostly for its ecological and recreational qualities.Regarding perception of the change, people are either positive or negative to the developmentwhich can be explained by people?s experienced sense of place and place attachment of thearea and the forest itself. The study has also shown that the urban planners rely on localinhabitants? view, as well as on expert knowledge during the process of planning.The results of the study contributes to a better understanding of why and for what purposesurban forests are important for the city dwellers..
Faktorer som påverkar lönsamheten vid köp av skogsfastigheter i Norrbotten
During the past 20 years, the price of forest estates in Sweden has raised more than the price of timber. The purpose of this study is to investigate if it, despite this development, is possible to buy a forest estate based on economic grounds. Different forest parameters will also be studied to analyse their effect on the profitability.
The study is done in cooperation with the company LRF Konsult. Purchase price of 34 forest estates near the coast of Norrbotten, Sweden, has been compared to yield valuation. For the valuation, guidelines from the Swedish author Lantmäteriet was used.
Den icke-monetära nyttans betydelse för prisbildningen på skogsfastigheter : en intervjuundersökning
The market value of forest properties can be assumed to consist of two components, a monetary factor and a non-monetary factor. The objective of this examination paper is to study the impact of non-monetary factors on the values of forest properties in Sweden. This study is based on a population of buyers of forest properties in the southern of Sweden. The results are based on interviews with 54 buyers. Of the purchases were 37 % new purchases.
Säsongsvis avverkning : det operativa traktvalets påverkan på den säsongsmässiga uthålligheten i ett bolagsdistrikts traktbank
Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical.
The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank.
The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data.
The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.
Non-state actors? role in the EU forest policy making : a study of Swedish actors and the Timber Regulation negotiations
The purpose of this research is to identify how E-NGO and forest stakeholders, in the study referred to as non-state actors, have influenced the EU timber regulation; through participation and lobbyism towards the decision- makers (policy makers) at EU and national level, to achieve adjustments in the legislative text. The study also examines the relationships between the forest stakeholders, the E-NGOs and the EU-institutions, regarding communication, cooperation, informal and formal consultation where interviews were accomplished with decision-makers from the EU-institutions, forest stakeholders, E-NGOS and representatives from Swedish authorities that participated under the development of the EUTR during the period of 2008-2013. The participation and lobbying from non-state actors have most likely affected the outcome of the regulation, through alterations in the legislative text and through influencing the EU-institutions. Several factors that have affected the efficiency and timing of the influence have been identified through interviews as well as various approaches to influence the decision makers. The findings of the study may be useful for forest related interest groups that are involved in decision-making procedures at EU-level and as substance and material for further research in the subject of forest policy making at supranational level..
