This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

The Swedish forestry aims primarily maximize production and economical wins. However, especially urban forests have great qualities as space for recreation and children?s play, which means that other goals should lead the forests management. The Teleborg forest is a wooded area in Växjö, surrounded by urban dwellings, schools, nurseries etc. A great part of the forest was wind felled during the storm Gudrun in 2005 which changed the forest, earlier dominated by spruce, dramatically.

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

Södra is a co-operative of private forest owner organisation which is owned by 35 000 private forest owers in southern Sweden. Forest owners in Sweden can choose to certify their Forestry. Södra uses PEFC (Programme for the Endorsement of Forest Certification Schemes) as their certification scheme for their members. Those who choose to certify their forest are obligated to follow the demands for forestry which PEFC requires. A ?Green? forestry plan is another important tool in the ambition to reach a sustainable forestry.

Fossila drivmedel står idag för en överlägsen majoritet av den totala användningen av drivmedel som dagligen förburkas. Alternativ till de fossila drivmedlen krävs för att säkerställa tillgång i framtiden. Försvarsmakten har fått uppdrag från regeringen att utforska möjligheten att övergå till att driva sina fordon på förnyelsebara bränslen.Militära organisationer strävar efter ett enhetsdrivmedel, alltså ett gemensamt drivmedel som driver samtliga fordon och enheter. Största anledningen är den förenklade logistik som kan uppnås om endast ett drivmedel används.Detta arbete har sökt efter ett alternativt drivmedel som skulle kunna användas som enhetsdrivmedel inom Försvarsmakten. Detta för att lösa problematiken med att både byta till ett förnyelsebart drivmedel och ett enhetsdrivmedel i samma fas.Slutsatserna som dragit i detta arbete är att FT-bränslen har potential att användas som enhetsdrivmedel ur ett tekniskt perspektiv.

In this study, some aspects of communication that are creating problems in a chosen forest conservation case are explored. Focus is on how the manager of a forest experience how he is treated during a formal decision of conservation. The paper also gives introduction to communication theory as well as to present forest policies in Sweden. Explanations of the most common concepts and terms in forest conservation is presented and such a understanding is necessary if the reader is to acquire enlightment from the material and the following discussion. This paper focus on a conflict between the county administrative board, a Swedish regional authority, and a private forest-manager. This is a case where the manager feels that the authority is forcing a sale of land, because the forest is being turned into a conservation area. The problems are not just economical, the manager feels mistreated and left out of the discussion, and the negotiation is long and problematic as shown in the interview and the case study. In the study, an in-depth interview is made with the manager of the forest, and a case study has been made based on the documents in the case attained from the county administrative board.

Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.

Today, a large proportion of wood supplied for the Swedish forest industry is bought from private forest owners while forest companies at the same time provide the forest owners with services such as logging services and transportation. Today, forest companies work extensively with keeping the time used for transport and logging short. But what does the private forest owners think about the time required for the timber deal, also called lead time, and the different parts of the timber deal. In this thesis, the forest owners? perception of the different lead times in their contracts with Stora Enso and their communication with the purchasers is examined.

This Master thesis is performed at the request of the forest company Mellanskog and the local municipality of Borlänge in Sweden and aims to establish recreational adjusted forest management plan for the areas of Mellsta and Skräddarbacken in Borlänge. In all types of urban forestry it is very important that the management plan are accepted by the general public. To make sure that also these plans of future measures, pass in the public, interview studies have been performed in which the public wishes and interests have been examined and applied in the management plan. To make sure that future measures in the forest may be accepted by the public when the forest harvester enters the woods, it is very important that a well functional work of information has been made. The people living close by the forest shall have been informed a couple of weeks before the time of measures and it must also be good information available that explains what is to be done and why.

This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.

The world economy of today is in an extensive financial crisis which has lead to the fact that people seek well placed investments and securing of capital, something that by many people can be found in forest investment. The price of forest estates has increased with 90 % during the last 5 years and marketing polls indicate a positive belief in the future among forest owners. The development of timber prices has not increased to the same extent as the forest property prices which implies that the property price not only reflect the yield value from the forest but also that the lumber value does not have such a meaningful role in the pricing of forest properties as proven earlier. This fact means that forest owners either invest their capital in forest in a speculative point of view or that the purchasers of forest properties invests in non monetary benefits that lacks a direct yield value. The purpose with this degree thesis is to increase the understanding of the pricing of forest properties with focus on the above mentioned fact.

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.

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.

The NIPF (Non Industrial Private Forest) owners in Sweden have very differentiated goals and needs with their forest. They have different backgrounds and some of them live at their forest estate while other live in an urban environment, and some are economically dependent on their forest estate while others are not. The heterogeneity among these forest owners creates problems for market actors that want to aim marketing messages to catch their interest. This is the problem background to the task that was provided to us as an investigative masters thesis for us. Their request was a plan for ensuring a successful marketing towards different segments of the NIPF owners. We commenced with a literature study based on market information and previously carried out similar investigations. We summarized the most important market information from the literature and created some hypotheses regarding goals and needs of the NIPF owners.
