Affärsrelationen - en studie av samspelet mellan drivningsentreprenörer och tjänstemän inom ett virkesområde hos Mellanskog
The purpose of this report is to investigate the business relationship between forest machine entrepreneurs and company officials within a timber area at one of the Swedish forest owner associations called Mellanskog. This report shows how these people work with their business relationships, what they believe are the keys getting a successful relationship and how they have got were there they are now.
Key words: Business relationship, cooperation, team work, communication, negotiation, respect, commitment and trust..
Processbeskrivning av Rundvirkestransport : En Fallstudie hos Tra?frakt Go?taland AB
Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.
Vindfällning i naturliga och skapade bryn och kanter :
The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types.
The data was collected from an electric power line going from the north to the south of
Sweden. The mean value of the clearcutted area around the power line was 120 meters. The
main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set.
The main parameter studied was the damage frequency at the edge of the forest compared to
the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated.
The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species.
A marked difference was observed between tree species and damage frequency.
Svält vid akut diarré hos hund, beprövad forskning eller gammal vana?
The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

Rörelsemönster och golvrenhet på två olika slags spaltgolv i lösdrift för mjölkkor :
About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.
Naturhänsynen i FSC-standarden : vetenskap eller gissningar?
The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.
Kommuninvånarnas syn på Sala kommuns skogar och skogsbruk
The municipal forests of Sala cover an area of 6 000 hectares, starting in the vicinity of the city and reaching north. At the same time as residents make abundant use of the areas closest to the community for outdoor activities and recreational purposes, the forest is of great economic value and also worth protecting for environmental reasons. These conditions make forestry in periurban woods more complex than conventional forestry, why a good understanding of the needs and demands on the forest and silviculture program is required. The purpose of this study is to depict the usage of the forests owned by the municipality of Sala, to set forth the common view of the silviculture program implemented by the municipality and to chart the expectations the community has on the forests and forestry of the future in the municipality of Sala.
The survey part of this paper consists of the interviews of thirteen individuals representing nine interest groups. As expected the views of these individuals varied widely but some results were expressed by more or less all of them.

Reducering av produktionstryck i A-linan : Förflyttning av produkt
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
Effekten av rollkur på hästens rörelsemönster och välfärd
This essay intends to provide an understanding of the developments in the right of public access and recreational activities in the forests of Sweden, and which factors and prerequisites that have affected this development. The forest and its history, along with recreational development has in many ways shaped today?s rights of public access, but there is also an age-old tradition of public access that has affected how we have used the forest, and that also has enabled the development of outdoor recreation. Many are unaware of this, which causes misunderstanding to appear around the rights of public access and how it is supposed to be used.The essay opens with historical descriptions of public access, the Swedish forest and outdoor recreation, to thereby provide a picture of how these three fields have influenced each other over the centuries. This is followed by a description of the current access rights and the problems associated with those, and a description of other countries' equivalent of the right of public access.
Bruksorten : Illustration om en resa.
The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.
Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?
The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners.
To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.
Metoder för att undersöka effekterna av naturvårdshänsynen i skogsbruket efter den nya skogsvårdslagen
In 1994 a new Forestry Act was accepted in Sweden. One of its aims was to raise the consideration for preservation of biodiversity. Since this happened over 15 years ago there is now an interest in analyzing if the law has been effective in its purpose. In this study methods suitable for analysis are being investigated. The study contents a pilot study of methods for five parameters that can validate if the law has been followed.
Environmental variables determining the occurrence of the red-listed Carbonicola anthracophila and C. myrmecina in boreal forests
The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.
