Mapping of clear-cuts in Swedish forest using satellite images acquired by the radar sensor ALOS PALSAR
This study presents results for observing forest changes in Sweden using multi-temporal L-band satellite data and is a part of the JAXA?s ALOS Kyoto and Carbon Initiative. An extensive dataset of images acquired by the Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR) is investigated for clear-cut detection in boreal forests in northern Sweden (Lat. 64°14? N, Long.
Kombinationsbruk, talltimmer och vilt?
When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.
Den geografiska, funktionella och processorienterade organisationen : en fallstudie av Holmen Skog, SCA Skog och Sydkraft Vattenkraft
This thesis reports on a case study of two different organisational forms in the Swedish
forest industry; the geographic and the functional organisation. The work in the
geographic organisation is carried out within districts under the supervision of an overall responible district manager, where as in the functional organisation the work has been divided into functions headed by function managers. Forest magement, logging and wood
purchases are examples of such functions. The general idea of the functional organisation
is having the functions working over a larger geographic unit, without subdividing
district boundaries of the region. Also a third organisational form of current interest for the forest industry; the process orientated organisation, is analyzed in the case study.
Here, a company outside the forest industry has been analyzed, since no forest company
was considered to have made as much progress of changing organisation to process
orientation.
In the report I present the results from qualitative interviews, where I give the reader a
picture of the motives behind each organisational form, what the form implies for some
of the company?s interested parties and the organisations? views on future organisational
development.
Föryngring i stormfälld rekreationsskog : en jämförelse mellan föryngring i produktions-, rekreation/produktion och rekreationsskog.
When the storm Gudrun hit Sweden on the 8th and 9th of January, many recreational forests in southern Sweden blew down. For this reason there is a demand for new regeneration methods as to how these storm-felled areas should be regenerated and with what species.
In this study the forest is divided into three areas: production, recreation/production and recreation. The first area is a forest with production as main goal and these kinds of forests are located a bit from the city. The second type ? recreation/production forest ? has two equal goals: production and recreation, and is located close to the city.
The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?
The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.
En undersökning av Bergvik skogs och Skogsstyrelsens gallringsmallar mot en gallringsoptimering på simulerade typbestånd
The purpose of this study was to analyze the two thinning models: Bergvik Skog´s thinning model, which is based on total stems and dominant height, And Swedish forest agency´s thinning model which is based on basal area, habitat index, dominant height and recommended number of stems at final felling in Heureka´s StandWise and PlanWise.
The data we chosen for our study were taken from the Swedish National Forest Inventory and we were creating a simulated stand based on a great number of sample plots in Region three from The Swedish National Forest Inventory. We had chosen to create one stand with low habitat index (T20) and one with high habitat index (T24). Our purpose were to come as close as possible to a natural stand in central Sweden. We performed the thinning in StandWise and analyzed the data I Excel files. Our thinning optimizing´s were performed and analyzed in PlanWise.
There wasn´t any big differences between the thinning on the lower habitat index.
Analys av artificiella marktyper vid vatten med hjälp av GIS, Värmlands län 2007
On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).
Stubbtransporter - en jämförelse av tre olika transportsystem
In Sweden, the demand for bio energy has increased in recent years due to the current energy and climate debate. In 2008, the energy supply of Sweden was 612 TWh, biofuels accounted for 123 TWh of these. Stumps have been highlighted as a potential fuel in recent years and the Swedish Forest Agency expects a technically and biologically feasible potential of 20.7 TWh annually between 2010 and 2019. The idea of utilize stumps is not new. During the 19th century stumps were used for tar production and during the 70?s and 80?s attempts were made to use stumps in the pulp industry.
Privata markägares reflektioner med hänseende till den minskade röjningsaktiviteten : så kan skogsvårdsstyrelsen anpassa sitt arbete
This project was a request of Norrbodal´s Forestry Board, Västra Götaland. It was performed as a qualitative interview analysis of private forest owner?s deficient motivation regarding pre-commercial thinning. The purpose of the project is to investigate what the Forestry Board can do to motivate private forest owners to do more pre-commercial thinning.
The results build upon 16 qualitative phone interviews with forest owners that have their forest within the district of Norrbodal. The owners are divided into two groups, the one who have performed the pre-commercial thinning and the one that has possible pre-commercial thinning needs on their properties according to the pre-commercial thinning analysis ,which is the result of a satellite analysis.
Öppen tävling Filmfestivalens strategiska fördelar i en digitaliserad filmbransch
This paper investigates strategic opportunities for film festivals in a digital film business, with emphasis on Göteborg international film festival and the Swedish film industry. Using a theoretical framework of strategy analysis, the film value chain is examined with special regards to disruptive technology, and the film festival's unique resources are linked to industry structure. It is shown that relationships between actors and across sectors are crucial features of the film industry, and hence a network perspective is added to the theoretical framework. Barriers to entry are shown to be relatively low in all sectors except the cinema market, and it is proposed that film festival's could expand into digital distribution, taking advantage of brand strength, customer loyalty and knowledge of industry. The study adds to the mounting research on film festival practice and its significance for marketing and distribution in the film industry, and highlights the emergence of strategic openings in destabilized networks..
Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?
Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.
Hur olika skogsägarkategorier har försett sig med underlag för beslut och åtgärder efter stormen Gudrun : en jämförelse av medlemmar och icke-medlemmar, åbor och utbor samt kvinnor och män
During the 8th and 9th of January 2005 a devastating storm named Gudrun entered the south of Sweden and a big part of the forest owners got their forests damaged. The study objective was to investigate on which basis and how the affected forest owners made their managment decisions immediately after the storm and if there are any differences between different categories of forest owners.
- Members ? non members in a forest owner association (FOA)
- Resident owners ? non resident owners
- Female and male forest owner
The study is based on a questionnaire survey with the purpose to examine the most important counsellor and information channels of the forest owners. A total of 450 forest owners participated in the survey.
Results show that all categories of forest owners prefer professional counselling rather than personal counselling.
Från gles skog och brokiga ungskogar till homogen produktionsskog : en skogshistorisk studie av Hällforsmarken under 1900-talet
The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.
Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft
The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.
Utvärdering av produktionsrapporterad volym för contorta
The background to this study is that the forest company, Holmen, has found large discrepancies between harvested volume and the measured volume at the industry. Factors like bark features, breakage, double tops, bends and stem damages was noted, and all stems were measured manually. Hypothesis testing with the method "random in pairs" were used to examine whether the harvester measured values significantly differed from the manually measured.
The result of a properly calibrated harvester shows in average underestimation of the volume with Skogforsk Pine as a bark function. This means that the harvester isn´t the reason why the volume measured in the industry is lower, the fault is elsewhere. The study also indicates a need for a unique bark function for logepole pine..
