Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891 Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.

According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.

Sweden?s District councils and Country councils are in itself to a large extent responsible for the state financed welfare. Because of this, Sweden has a contribution- and adjustment system. The reason for this system is to create equal chance, for all District councils and Country councils, to be able to give the citizens service independently of their income and non-influential structural differences. The adjustment is built upon the so-called standard cost method, which contains four different parts.

Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.

During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.

Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.

This is the project of making a stage design for Batboy ? the musical, a cooporation with a network of musical artists. The aim of the project was to create a space on stage that strengthens and expands the experience of the story told, and find design solutions that give an extra dimension to the story. The prerequisites for my work were partly defined from the produc¬tion, as were my limitations. In the cast of ten artists some were to play more than one role, often one of the opposite sex.

Young councillors are currently under-represented in Sweden's municipalities. Young councillors are also stepping down in greater numbers than older members. This paper explores the reasons why young councillors choose to resign from their mission, so to identify possible remedies to the problematic trend of underrepresentation of younger people in local authorities in Sweden.This qualitative essay intends, through interviewing politically-active young people who has left their assignment, to study the reasons for resignations from elected posts. To see what could be the reason I have looked at previous studies and theories about opting out but also tried to remain open to identifying new and emerging trends previously undetected in existing surveys.The results showed that the political assignment proved to be too time-consuming, with young people choosing to spend their time on career and leisure. Those who resign from political life often express criticism towards the Municipal Council; they consider it tedious and many complain of having little influence.

The Department of Forest Products and Management, Swedish University of Agricultural Sciences has received means from Vinnova for a preliminary study of the organisation of logging work of today and how a better logging organisation should be brought about. This thesis reports results from qualitative interviews with nine forest machine contractors regarding the situation of their companies. The interviews have been analysed with respect to the genesis of the companies, which tasks they perform or that they could consider perform-ing, business relationships of the companies, relationships between the different partners of the companies, and the state of competition experienced by the contractors. The companies have developed either from the contractor previously being machine operator employee or from that the contractor in making has owned a machine and needed work. Their primary business is mechanised logging.

This qualitative study examines how emergency people are framed in Swedish evening-, and local newspapers during the forest fire in Va?stmanland, Sweden 2014. The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.

The digital map product kNN-Sweden contains nationwide data of the country?s forest land. The estimated forest variables are mean age, mean tree height, volume per tree species and total volume. Today Södra Skog?s assessments of timber potentials are mainly based on experience rate and subjective assumptions.

A growing number of Swedish forest owners are choosing to certify their forestry. However, there appears to be a lack of field surveys which describe differences between certified and non-certified forests concerning the degree of completed environmental considerations. In order to know to what extent certified forests contribute towards improved environmental consideration, we need studies on how large the difference is in relation to non-certified forests.Differences between certified and non-certified forest clearings were quantified through an inventory of the number of retention trees, dead trees and snags. The result showed that the retained number of the investigated parameters varied greatly between individual clearings, regardless of certification status. However, the results suggested that the certified clearings had an average higher incidence ofthe investigated parameters.

The purpose of this study was to show how the Hybrid Larch (Larix eurolepis x) are used by large herbivores in terms of grazing and fraying. More specifically I studied how impact on the seedlings was affected by forest stand area, tree height and stem density (stems/ha).The survey was done in Jönköpings county in southern Sweden. About 50 % of all stems that are measured are damaged by grazing and 5,8 % was damaged from fraying. The conclusion of the study is that the biggest influencing factor is the height of the seedlings. The size of the stands and number off seedlings per hectare have almost no impact on the injuries on the seedlings. Fraying are common on trees smaller than 3 meters, and doesn?t occur on trees above that height.
