The aim of the study was to compare how the population of pine (Pinus sylvestris) and spruce (Picea abies) have changed between 1927 and 2013 in the oak landscape south of Linköping. A field study was carried out in 22 two kilometre lines which also had been studied in 1927. In these lines, which where ten meters broad and had a direction from west to east, the pines and spruces were counted, measured and classified by steam diameter. The obtained result was that the basal steam area (m²/ha) had increased for pine (44%) and spruce (57%) between 1927 and 2013. The amount of trees had increased in all diameter classes except thinner pine and spruce with a diameter of 5-10cm.

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

Icke vinstdrivande organisationers förtroendeskapande webbkommunikation är en undersökning som syftar till att öka förståelsen för hur icke vinstdrivande organisationer etablerar förtroende i sin kommunikation på webben. Genom att analysera hur de tre icke vinstdrivande organisationerna Forest Stewardship Council (FSC), KRAV och Fairtrade skapar förtroende i textmaterial presenterat på respektive organisations hemsida söker uppsatsen belysa hur olika förtroendeskapande grepp används av icke vinstdrivande organisationer för att etablera förtroende mot allmänheten. Analysen visar att det mest förekommande sättet att skapa förtroende mot allmänheten bland de studerade icke vinstdrivande organisationerna är att framhäva sin expertis på det område organisationen verkar. Uppsatsen öppnar upp för ett nytt forskningsområde med fokus på hur den icke vinstdrivande organisationen etablerar förtroende på webben. För vidare forskning kan det vara intressantatt öka antalet analyserade organisationer för att öka möljligheten att fastslå samband mellan hur stor grad av förtroende allmänheten upplever sig ha för en organisation och vilken typ av förtroendeskapande kommunikationen organisation använder sig av..

This essay examines the criteria for a peaceful cemetery. First there is a short history of the Swedish funeral place. After that follows the definitions of a peaceful place according to environmental psychology. From these definitions an analysis method is constructed for identifying a peaceful cemetery. The analysis method contains six criteria, shape of the entrances, existence of sound, vegetation character, the cemetery?s demarcation, the cemetery?s management and what feeling the cemetery mediates.The analysis method is put into practice on three cemeteries, Överklinten cemetery, Stockholm forest cemetery and the old cemetery in Malmö.

Användningen av bränslen med skogligt ursprung har i Sverige ökat stadigt sedan 1980-talet. Tänkbara anledningar till ökningen är en ökad medvetenhet kring enregisystemens miljö- och klimatpåverkan samt att energipriserna stigit och gjort det lönsammare att ta ut bränslesortiment från skogen. De främsta förbrukarna av dessa bränslen är idag den svenska industrisektorn och kraft- och värmeverk. Samtidigt som denna ökning har skett så har stora förändringar gjorts inom det svenska skogsbruket vilket gått från att inom drivningen haft många människor anställda till att idag vara så gått som helt entreprenörsbaserat. Även dagens uttagssystem för skogsbränslen är entreprenörsbaserade och förädlingskedjan för skogsbränslen sköts idag av ett fristående entreprenadföretag som utför de olika processerna i kedjan. Syftet med denna studie är att kartlägga hur uttaget av skogliga bränslesortiment går till idag och hur avtalsförhållandena för de till uttaget och vidareförädlingen kopplade tjänsterna ser ut.

The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.

In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study consisted of two separate field tests; in the first, two 300 m2- plots in western oak dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen. In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden.

Human presence has always influenced the surrounding areas, the forest as well. Structure and species composition have changed during human land use. Knowledge regarding these changes should be of great interest for conservation and forestry. We have analyzed human impact on the tree species composition on five study sites during 2000 years in Ångermanland, Sweden. More specifically the change in tree species composition in percentage amongst alder, birch, spruce and pine over time.

AbstractThe purpose of my study is to examine how preschool children experience nature and how the educationalists at the preschool can make nature more exciting and support the children?s personal growth. I have also studied what the educationalists of the preschool do and what they can do to make nature more interesting and playful for the children. Observations and interviews have been conducted at a preschool in a small town. The preschool is situated close to nature, that is, close to a small forested area.

Tree fiber lengths controls properties like strength and smoothness in paper and other wood products. For forest researchers it is of interest to be able to determine the fiber lengths in standing trees. Mo?rling et al. (2003), among others, have developed methods to estimate fiber length distributions in standing trees without damaging them.

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

Outdoor education is a teaching method which has several advantages to traditional classroom tuition. Its ideas have a long tradition and find support in the current Swedish curriculum. The place for the tuition is a central aspect within outdoor education. This essay aims to investigate what good places for outdoor education look like as well as discussing how the characteristics of such places can be used when designing schoolyards. Previous research shows that nature has characteristics that suit outdoor education well.

I uppsatsen utreds de svenska personaloptionsreglernas förenlighet med EG-rätten. I 10 kap. 11 § 2 st. 2 p. IL framgår att då en i Sverige obegränsat skattskyldig person upphör att vara bosatt eller att stadigvarande vistas i Sverige likställs flytten med att personaloptionen utnyttjas och skall därför beskattas.
