People have utilised and influenced the boreal forest for many centuries. Prior to the industrial revolution during the 19th century, however, human use primarily only had a low impact on the forest. When the timberfrontier swept over the country, the Swedish forests came to change for ever. The study site for this thesis is situated in the northern part of the county of Västerbotten, Sweden, and has previously been a National forest. Today the area is an ecopark and the land is owned by the forest company Sveaskog.

Förorenat dagvatten från Stena Gotthards metallåtervinningsanläggning i Eskilstuna har filtrerats genom kolonner innehållande två olika adsorbenter, torv och furubarksflis. Torv är en organisk jordart som främst används som bränsle och furubarksflis är en biprodukt från skogsindustrin. Båda filtermaterialen är relativt billiga och finns i stora kvantiteter i Sverige. Filtermaterialen har visat sig ha varierande kapacitet att adsorbera metaller i vatten på grund av själva materialet samt vattnets sammansättning. Resultatet från den här studien visar att av de två undersökta filtermaterialen så har furubarksflis störst kapacitet att reducera bly, koppar och zink från det specifika dag vattnet..

Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

The fragmentation and reduction of deciduous forests in Sweden is threatening many species. Particularity worrying is the loss of broad-leaf trees, since a diversity of species is often associated to them. Today many deciduous trees are situated along the border between forested and open areas, and these small fragments can be important for biodiversity.The aim of this study is to analyze if wildlife management can affect the variation of deciduous trees and bushes in the landscape. In brochures and literature Svenska Jägareförbundet (the Swedish Association for Hunting and Wildlife Management) recommend hunters and landowners to promote deciduous trees ? often broad-leaf trees ? as wildlife management measures, while the Swedish forestry laws can be sensed as unclear regarding the treatment of these trees.Five properties in Södermanland, Sweden, were chosen as study areas and inventoried in respect of trees and bushes in September 2013.

The use of bio energy in Sweden has increased during the last few years and with every passing year, bio energy produces 3-4 TWh´s more energy than the previous year. The increase in the use of bio energy makes it an interesting prospect for forest companies to produce bio energy from the forest. Sveaskog has a fairly extensive bio energy programme, mainly in southern and middle Sweden. Their activity regarding bio energy in northern Sweden has been very restrictive or even non-existent. Because of this, during the winter of 2003-2004, Sveaskog initiated a number of degree projects with the purpose of looking at the use of bio energy in northern Sweden.

The essay describes the bachelor project by Marie Hanås, in collaboration with Skälsö Arkitekter. Skälsö Arkitekter are currently developing an area in the north of Gotland, Bungenäs; previously home to lime stone quarries and military bases.The brief was to design a set of outdoor furniture to complement the new development. The main effort of the project was in designing furniture that would fit the environment visually but construction issues were a major secondary concern, to ensure the easiest possible manufacturing. A reference group of coastal house owners were interviewed, and their feedback, together with an analysis of functions, trends and target groups, were the base for the ideas.Of the five concepts presented, Skälsö Arkitekter chose one to develop further. This was done through sketches, models and 3D models and led to the final result which is lightweight furniture of Gotlandic pine wood with an industrial touch.

A few hundred metres from the beach on Fårö, Gotland, is a small lot with pine trees, green moss and wild fl owers situated, owned by my brother and sister. Eventually they would like tobuild a summerhouse here, in close proximity to their relatives. My project is a proposal for the summerhouse at the site, within the restrictions of 61 m² building area, with focus on interior,exterior and the environment.My proposal is a house close to the surrounding nature, with reference to the the building tratition on the island and with local materials. Orientation to the sun, road and neighbours hasall infl uenced my ideas of this house and the relation between inside and outdoor living, were important in my creative work. The aim was to create a house made for the family and theirholiday lifestyle and allowed consideration for the possibility of a growing family with more children.

The purpose with this report is to compare moose browsing in young stands within a small game preservation, and if there are any differences between two areas. The method used in the inventory is a local damage caused by moose browsing survey. It is suitable on areas that have more than 50 hectares but less than 250 hectares of young forest. Inventory of moose browsing is best done on bare ground in the spring and should preferably be done before the flushing begins at the pine. Orsblecks game management area is divided into two different moose management areas, Noppikoski and Siljansringen. During the winter Siljansringen has a denser winter strain of moose, because of the moose seek out lower parts with less snow during the winter. This should also lead to the southernmost part should accommodate larger proportion of damages caused by browsing by moose.

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

The Swedish Forestry Research Institute implemented an experiment which began in the year 1979 in a by moose browse damaged area in Sweden. An audit in 2014 of the moose browsing study called ?Furudalsförsöket? is the underlay to the study's results. By comparing Scots pine stands development in relation to known damage obtained thereby gives the understanding of how browsing affects the short and long terms impacts of Scots pines quality and volume production. The results of this year's audit reveal that the standing volumes in the undamaged and damaged areas represent a significant difference. The number and volume of the ingrown trees constitute a larger proportion of the areas that have been heavily browsed. It also proves once again that that all damage classes had a downward trend, which means that the damage is concealed with time.

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.

The purpose of this study was to show how the Hybrid Larch (Larix eurolepis x) are used by large herbivores in terms of grazing and fraying. More specifically I studied how impact on the seedlings was affected by forest stand area, tree height and stem density (stems/ha).The survey was done in Jönköpings county in southern Sweden. About 50 % of all stems that are measured are damaged by grazing and 5,8 % was damaged from fraying. The conclusion of the study is that the biggest influencing factor is the height of the seedlings. The size of the stands and number off seedlings per hectare have almost no impact on the injuries on the seedlings. Fraying are common on trees smaller than 3 meters, and doesn?t occur on trees above that height.

This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.
