The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

The objective of this thesis was to investigate what influence nature conservation measures taken at regeneration felling. Factors analysed were the forest owners´ situation and their characters, and information activities from wood-suppliers and the Regional Forest Board (RFB). The inventory was performed with a posted questionnaire followed up by telephone to forest owners and a posted questionnaire to wood-buyers. The forest owners were grouped in three strata, depending on the quality results (D- polytax inventory) of the taken forest conservation measures, and for this investigation forest owners were sampled from the population in the tree groups. In total 73 % (41/56) of the sampled forest owners answered the questionnaire Group A (17 answers): Good judgement Group B (19 answers): Bad judgement Group C (5 answers): This group was formed from the forest owners that were informed, by RFB, about nature conservation measures and culture history consideration before the regeneration cutting.

The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done. We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden. The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.

Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.

SUMMARY Establish a pasture There is many valuable nature and culture landscapes in Sweden that has developed during a long period of time, throw natural processes or human use. Unfortunately lot of these are disappearing. My thought with this work is to explore the possibility to establish new areas with similar qualities. The motive for this is that attractive countryside biotopes are well worth to use as model to enrich the urban landscape. Another thought has concerned the people that establish, build and manage landscapes and parks. They often have varied views, both coming from a difference in background and previous experiences.

This thesis reports on a case study of a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company. The pulp industry which produces the ash, the forest division which would be responsible for identifying land and spreading the ash, and Stora Research, which has had a major part in the design and implementation of research trials. Lacking an overall company decision on ash recycling the matter is left to the individual divisions.

FSC, Fairtrade och SSC Forestry har tillsammans startat ett pilotprojekt som handlar om att skapa rättvisa möjligheter till handel och hållbart skogsbruk för småskaliga skogsbrukare i utvecklingsländer. Kährs har köpt in detta virke som är dubbelcertifierat med FSC och Fairtrade och producerat ett golv av virket. Syftet med undersökningen var att ta reda på privatkonsumenters preferenser vid köp av golv och hur högt certifieringar värderas vid sådana inköp. För att ta reda på detta genomförde vi en kvantitativ marknadsundersökning och vi använde oss av conjointanalys för att utforma och analysera denna. En conjointanalys undersöker vilka avvägningar en konsument gör vid inköp av en produkt med flera olika egenskaper och man får fram vilka egenskaper som är viktigast.

The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A). The main purpose with this report is to look at three questions: 1. How does the supply chain look today? From forest to industry. 2.

The aim of this study is to find out if there is any difference between how a state-owned company and a publicly listed private company communicate its sustainability performance in its sustainability report. It also aims to find out if the communication regarding sustainability has changed over time. The poll was conducted in two Swedish companies, Sveaskog AB and AB SCA, operating in the forestry industry and through a quantitative content analysis, the companies' sustainability reports from 2005 and 2010 were examined. To get a result, the reports has been examined by the GRI framework (Global Reporting Initiative) and an assessment of the communication was made based on a scale of 0-3. The results has been evaluated based on stakeholder theory, legitimacy theory and the growing interest in CSR. The analyses found evidence that there is a link between the form of ownership of the company and how it communicates regarding sustainability.

The goal of this work is to get as good a basis as possible to explain what the owners want for products and services when those doing business with buying groups in Korsnäs purchases regions: Gävleborg, Dalarna, Uppland and Frövi. It should also provide Korsnäs knowledge of the most important factors to consider in business with the owners. Another important aspect is to find out what you have done better at the business with owners, to eventually be able to preserve and take them into account. 300 questionnaires sent out to randomly selected owners in these regions. This is to find out what the owners did not have the products/services of Korsnäs. 29 questions were asked in the affected areas to identify what was missing and to eventually be able to satisfy them.

Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

To be able to plan different treatments, accurate data is required. The collection of data is often expensive and that?s why the aim is to lower the inventory costs without loosing the accuracy of the data. Holmen Skog has in its strive to lower the costs, decided to evaluate two different methods for forest delineation, computer aided forest delineation and digital stereo view. This study?s purpose is to evaluate these two methods in regard to usability for a beginner and how good the delineation gets.

Bakgrunden till detta arbete är att Bioenergi i Luleå AB måste tillmötesgå kundkraven för att behålla sina marknadsandelar och ha möjlighet att utöka dessa. På senare tid har de stora kunderna börjat efterfråga bränslepellets som är certifierad enligt Forest Stewardship Council, FSC. Examensarbetets syfte var att hjälpa Bioenergi med framtagandet av en Forest Stewardship Council Chain of Custody certification. I den inledande kartläggningen användes i huvudsak intervjuer och observationer för att studera de anställda och tillverkningen. För att identifiera aktiviteter och brister i Bioenergis system studerades även interndokumentation och relevant litteratur.
