Epixylic lichens and bryophytes in young managed forests : substrate preferences and amounts of dead wood
Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .
Integration mellan skog & förädlingsindustri : en intervjuundersökning
The aim of this master thesis is to study the integration in Sweden between forestry and bulky industries as fiber- and sawmilling companies. The analysis is based on theories about transaction cost economies and competitive strategy. The studied companies are active on the Swedish roundwood market. The buying actors on this market were divided into two groups; fiber- and sawmill industries. Three companies from each group were chosen subjectively by the author.
Tornedalsk identitet : En studie om identiteter och deras påverkan på synen av den svenska staten
ABSTRACTThis C-essay in political science is written by Ingrid Karlsson, autumn 06. Advisers: Gregg Bucken-Knapp and Susan Marton.? The identity of Tornedalen, a study about identities and its affect on the view of the Swedish state.?The purpose of this essay is to investigate the identification amongst the population in Tornedalen and if their identity affects the view of the Swedish state. I am going to look into how people from that region looks upon their identity. Do they consider themselves as Swedish, Tornedaling or Finnish? I have two research questions on this topic: 1) What does a person from Tornedalen consider their identity? 2) If the way the Swedish state treated Tornedalen, from around the middle of the nineteenth century to the middle of the twentieth century, has affected the way people from this region looks upon their own culture, and if the treatment has affected peoples view of the Swedish state.
Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :
Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
Vindfällning, tillväxt och plantuppslag i en 13-årig granskärm i Medelpad :
The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.
Eld som naturvårdare : Kärlväxtflora och vegetationsutveckling efter naturvårdsbränning i två småländska naturreservat
This study has taken place in two nature reserves in the municipality of Uppvidinge in the Kronoberg region in southern Sweden. These have been chosen by the County Administrative Board to be part of a bigger landscape of fire affected nature, and prescribed fire has been implemented in these. The areas are called Ösjöbol and Berga fly and have been burned 2012 and 2013 respectively. Non-burned areas have been inventoried as well. Vascular plants and mineral soil have been inventoried with the Hult-Sernander-Du Rietz scale of five levels. Issues emanate from the County Administrative Board?s goals for prescribed fire: how sticks and herbs were affected, how much soil was uncovered, how the structure and fire favoured species were affected, and how deciduous trees and spruces (Picea abies) were affected. The study shows that the soil increased, as well as the fire favoured species.
En bortglömd guldålder? ? Tillgängliggörande av tidig svensk film till en bredare publik
Early Swedish films from the 1910?s and 1920?s are not only an important part of Sweden?s cultural heritage, but also an important part of the international film heritage. This period is often refereed to as the golden age of Swedish film history. Despite this fact, the possibility to watch Swedish films from this period is very small and the main purpose of this thesis is to examine why the availability of these films has such low priority in the Swedish film policy and at the Swedish Film Institute. With the use of policy analysis, I study governmental policies and policies from the Swedish Film Institute for early Swedish films and seek to identify the policy problem and its different parts.
Swedish Meats : motiven bakom försäljningen av kooperationen
In 2007 Swedish Meats, the dominant Swedish meat-producers cooperative sold its slaughtering and processing industry. The goal of a producer cooperative structure is to create value for members through vertical integration, and to strengthen members? market position. When Swedish Meats sold the slaughtering and processing components, it ceased in some respects to serve the function of a cooperative. This is a lost opportunity for both members and non-members, because Swedish Meats as a functioning cooperative could have exploited its dominant market position to positively effect producer?s prices.
Askgödsling och dess lämplighet i torvmarksskogar tillhörande Sveaskog Förvaltnings AB : en litteraturstudie
During whole-tree harvesting, there is a risk that the soil will become impoverished of nutrients. To prevent this, nutrients are returned to the harvested site as wood ash. This action also reduces the risk of soil acidification. Nevertheless, the ash does not result in any increase of tree growth if it is added on mineral soils, which is where the measure is most commonly used in Sweden. Due to the lack of growth response, the interest from landowners is small, which is why ash amendment today is not done enough to compensate for the need.
Vad kan man egentligen tro? : En läroboksanalys av läroböckers etikavsnitt utifrån breda och tunna etiska begrepp.
The following essay examines if five Swedish textbooks aimed for religious studies in upper secondary school might show similar flaws to those presented by the Swedish Schools Inspectorate in their review of religious studies conducted in 2012. The method used in this essay is a qualitative study of Swedish textbooks influenced by Lantz definition of wide and thin ethics. This in practice means that I have analysed the five Swedish textbooks using thin and broad ethics while conducting the analysis of the five. The purpose of the essay was to see if the flaws presented in ?Mer än vad du kan tro? regarding ethics and moral education might be present in Swedish textbooks as well.
?Varför jag lära svenska...?- några invandrarkvinnors syn på svenskspråksinlärning
ABSTRACTThis study focuses on immigrant women in Sweden and how their perceptions of resource loss may affect their motivation to learn Swedish. Focus group discussions were conducted with immigrant women who partake in a Swedish language learning project. Their Swedish language skills were very limited, and all of them had no or very few years of elementary level education. Results of the study suggest that the strongest motivator to learn Swedish is its potential role in facilitating everyday activities. .
Kvalitetsarbete i grotskotning
This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
