In January 2005 large forest areas in south Sweden were severely damaged by storm. This final thesis describes the work with creating an ecological and landscape-adapted regeneration plan for a severely storm damaged property in Kronobergs region in south Sweden. This regeneration plan, in difference to more regular plans, are focusing more on the owner?s use and goal?s for the property and seeing the property from a more comprehensive view in the regeneration process. Beside production and environmental values the plan also take in consideration other values as aesthetic, culture history, landscape picture and recreation values.

Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

The traditional Swedish way of dealing with browsing damages made by moose, is to reduce the moose population. However, a growing way of dealing with damages made by several ungulate species, including wild boars in particular is to redistribute them with supplementary food sources. Attracting them to settle in habitats less vulnerable to damages made during foraging. This study we tracked collared moose in southern Sweden from January throughout April in the year of 2009. From the tracking data their ?favourite? positions was selected and visited in order to study the features that attracts moose during winter.

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.

This is a literature review of how the climate change affects the forest growth innorthern Sweden. The temperature will rise about 5 °C with the largest increase in thewinter season (December - February) and the CO2level in the atmosphere is expected tobe doubled. Precipitation patterns will change and increase with 25-35 % and theprecipitation will be in form of rain rather than snow. Today the forests in northernSweden are entirely dominated by coniferous stands. This may shift with the climatechange and results in a larger number of deciduous trees, preferably birch will becomestronger and grow better and faster.

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

AHA is a Swedish abbreviation of "reveal threatened park and avenue trees" and is a method to assess the conservation value of individual trees, mainly in the park environments but also in natural stands. This method has previously only been practiced in southern Sweden (Sörensson 2008). To see if this method could provide satisfactory results in northern Sweden, I have studied it in areas around the Umeå River. This was done by studying the relationship between trees with different classifications of conservation value (as classed by the AHA method) and their content of species (species richness and abundance). Insects were collected using trunk window traps in a period of 13 weeks during the summer of 2014.

Uppsatsen behandlar de svar som gavs av de ungdomar som deltagit i studien angående kodväxling, en form av språkblandning. En förutsättning för att den här typen av språkblandning kan ske är att talaren erhåller en tvåspråkighet där det ena språket är mer dominant än det andra. Det språket som är dominant är i den här undersökningen är svenska och det så kallade gästspråket som kodväxlingen sker på är engelska. Kodväxlingen skiljer sig dock från låneord och importord då kodväxlingsord ännu inte blivit accepterade som låneord och importord i det svenska ordförrådet.Kodväxling har implementerats i det svenska språkbruket i flera decennier genom flera språk, framförallt franska och tyska under dessa länders storhetstider (Birch-Jensen 2011:146). Under senare delen av 1900-talet har dock kodväxling främst kommit att ske på engelska.

In Scandinavia, capercaillie are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports on the selection of the diet in spruce forest areas in Sweden.

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.

In Sweden, harvesting pre-commercial thinning (PCT) stems for energy purposes is a interesting way of financing the high cost of preparing dense stands for a profitable first conventional thinning. This concept can be labelled bioenergy thinning. The aim of this study was to quantify the productivity of a Vimek 404R light harvester with an accumulating Naarva-Grip cutting head during the bioenergy thinning of a self-regenerated stand west of Sunnansjö in Dalarna. The stand was birch-dominated, contained 15 371 stems/ha, and measured on average 4,6 cm Dbh and 7 m tall. Even though the driver was well experienced with the machine, the stand in question was the first one that he ever thinned in this manner. Nevertheless, the driver strived to accumulate as many stems as possible during each crane cycle and chose to cut taller stems in half so as to make the handling and forwarding of the harvested stems easier.

Fresh Kills park and the The High line park in New York, Downsview park outside Toronto the birch landscape at Shiphol Airport have something more in common than being big new park landscapes.They all include thoughts and images about ecology. These images are neither typically nature picturesque nor typically garden stylish. In Sweden we have the biotopes of Ankarparken, the new design of Kristinebergsparken. At Chelsea Flower Show in England Swedish nature put in a garden format is winning awards. There are some new ecological influence in the air.

Populärvetenskaplig sammanfattning: Kan satellitbilder användas för att studera skador på bok och ek?Sedan mitten av 1970-talet har man sett ökande skador på skogen i stora delar av Europa. Olika storlek på skadorna och att storleken på skadorna skiljer sig åt beroende på var man befinner sig har gjort det svårt att förklara orsaken. För att undersöka ifall skadorna även ökat i Sverige har Skogsstyrelsen utfört inventeringar på bok- och ekbestånd i södra Sverige under tre tillfällen; 1988, 1993 och 1999. Resultatet från undersökningen visar att konditionen hos bok och ek i södra Sverige har försämrats sedan den första inventeringen 1988.
