During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..

This final thesis is performed on commission of Torsby forestry administration, Stora Enso Skog. Stora Enso Skog is one of the major forestry companies of Sweden. The main business area is located in and around the region of Bergslagen. During the last decade the practice of forest management has rapidly changed due to a new forest legislation. The new law has resulted in that the production goal is equal to the environmental goal within forestry.

Taking a qualitative approach, this research investigates different theories and methods for creating parks that people will cherish and visit during their daily life. It also takes on the task to understand how principles of developing recreational values in a small forest is affected by the addition of a new element to the landscape, i.e. a major highway. Data was collected through the combination of focused literature review and study trips. This provided a framework which in turn was applied to the subject of the study, i.e.

The main objective of this study was to investigate the possible design of a horticultural therapy program in Swedish correctional treatment facilities. In the USA the use of horticultural therapy in offender rehabilitation is much more frequent compared with Sweden. The aim of these programs typically contains education for inmates. Research has been made indicating that these programs can have positive effects on psychosocial behavior and on vulnerability to substance abuse among incarcerated offenders. In this study the examples of these programs was categorized and analyzed from three perspectives; Vocational, social and therapeutic horticultural programs.

Fungi are everywhere around us and recently, there has been an increased interest in their role and importance in the forest. The fungi have several strategies to acquire energy and nutrition; one example is a mutual symbiosis with trees and plants - another being dissolving organic materials. Attempts have been made to better understand the circulation of nutrition in coniferous forests, and how fungi cooperate. Trees and plants have adapted with mycorrhizae and are now interdependent which is important to consider in forestry. A great number of fungi depend on dead wood and old trees to set fruiting bodies and spread further. These fungi also create environments for other species, such as birds and insects. The vegetation of a forest is determined by a series of factors; tree species, how old the forest is, soil type, as well as the ability of the fungal spores to spread and establish. Furthermore, in determining vegetation, the fungi?s ability to compete in the soil matters. These factors are nearly unexplored. Researching fungi knowledge and interest, a survey was distributed to five groups of people. The groups included forest owners, high school teachers, high school students, senior citizens, and a fifth group - ?o he ? - consisting of people of mixed ages and backgrounds.

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration. The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Bakgrunden till detta arbete är att Bioenergi i Luleå AB måste tillmötesgå kundkraven för att behålla sina marknadsandelar och ha möjlighet att utöka dessa. På senare tid har de stora kunderna börjat efterfråga bränslepellets som är certifierad enligt Forest Stewardship Council, FSC. Examensarbetets syfte var att hjälpa Bioenergi med framtagandet av en Forest Stewardship Council Chain of Custody certification. I den inledande kartläggningen användes i huvudsak intervjuer och observationer för att studera de anställda och tillverkningen. För att identifiera aktiviteter och brister i Bioenergis system studerades även interndokumentation och relevant litteratur.

Biological pest management is defined as control of pests using their natural enemies. This method has been used in Sweden since the 1970´s and it has been developed ever since. Biological pest management is today relatively common among commercial growers but there are good possibilities to apply this method in the home gardens as well. The aim with this thesis is to compile a report from both the companies that are marketing the products and the home gardener´s point of view. This should give a better understanding of the market and how it could be improved. We will give examples of products that represent the different kinds of organisms that are being used in biological pest management. Our hope is that this will be an introduction to all interested in biological pest management. The legislations regarding registration of organisms are still a matter of discussion and are causing problems to producers, distributors and the market in general. Why isn´t biological pest management more common in the home garden? The main reason appears to be the lack of knowledge in the subject. What are the benefits using biological pest management when it requires so much knowledge and it´s more expensive than conventional pest management? With the environmental problems we face today, we hope that every single gardener has an interest in developing an environment as clean as possible, even if only in one's own backyard..

This study was performed in collaboration with Moelven Skog AB, Örebro district. The purpose of the study was to review existing literature in order to describe the current status of harvester based measurement technology as the way to provide information for calculating payment to the forest owners. In addition to this, a short survey was conducted to find out how a switch to harvester based measurement would affect the administrative workload on timber purchasers working for the district. The literature study shows that the harvester measurement technology is ready to use if it is combined with well-established routines for control of the harvesters, methods for automatic quality indexing of the timber and ways of creating pricelists specially adapted for harvester measurement. Pricing each stem seems to be the most promising method. Stem pricing has several benefits.

Vad finns det för grundstenar inom den amerikanska odlingsterapin och hur används dessa i det odlingsterapeutiska programmet på North Carolinas Botaniska Trädgård? Jag ville få reda på svaren och bestämde mig för att åka över Atlanten och göra en fallstudie om NC Botaniska Terapiträdgård. Väl framme upptäckte jag genom litteraturen och människorna insatta i ämnet att det fanns ytterligare en designmetod som heter Universal Design inom den amerikanska odlingsterapin som jag inte kände till sedan tidigare. Resultatet av litteraturen och mitt platsbesök visar att det finns ett antal grundstenar inom den amerikanska odlingsterapin och Universal Design som används på det odlingsterapeutiska programmet på NC Botaniska Trädgårdar. Grundstenarna är följande: Tillgänglighet, Tydlighet, Variation och Utveckling och dessa påverkar designen av NC Botaniska Trädgårdens nya terapiträdgård. Denna resa har givit mig en inblick i vad den amerikanska odlingsterapin innebär och hur designen av NC Botaniska Trädgårds nya terapiträdgård kan se ut..

Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

Lyckebo farm is the original name of the four building big farm, where year 2000, the former farmer established Maglarp/ Lyckebo golfcourse on his land of culture. In 2007, new owners are approaching the Maglarps golfcourse with thoughts of expanding the business. A first step in that direction is to form the area of the entrance, the specific area the visitors are staying at before entering the actual golfcourse to play. The designproposal is inspired by the peasant garden history of southern Sweden during the nineteenth centuary. It also aims to satisfy the demands of function and usefullness of a golfcourse today.

In order to create a forest management plan for the area of Hestra, a survey was conducted. People living in the area were given the opportunity to reply to the survey. The questions in the survey are both personal and forestry-related. The aim is to reach out to the different categories of people when it comes to age, living and the different aspects of visiting the woods.

This Masters thesis is performed at the request of the National Board of Forestry in order to investigate how the Swedish municipalities use their forests. The study is of general character with emphasis on the social values of the forests. The municipalities? purposes with their forests have varied over time, but lately the social aspects have been recognised as interesting. The social values of the forests can be defined as the values from the forests that contribute to the wealth of humans. This has socio-economic importance for the municipalities. The study was performed as a quantitative questionnaire survey, complemented with qualitative interviews.
