Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .

The aim of this study is to describe how a theme about vitamins and analytical chemistry can be planed and implemented in a summer research school managed by AstraZeneca. The description of the theme is intended to be used as an instructor?s guide to upcoming summers-research-schools with the same theme. The students, which participated in the summer school of 2007, went to upper secondary school. During the summer school they were going to investigate the content of vitamin C in different fruits and vegetables.

Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited. The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.

Det här examensarbetet handlar om Nötbolandet, ett gammalt fritidshusområde sydöst om Örnsköldsvik, som till stora delar omvandlats till åretruntboende. Örnsköldsviks kommun vill gärna ha en översiktlig planering av området för att kunna styra utvecklingen. En sådan planering finns inte idag. Exploateringstrycket i Nötbolandet är stort och det finns många förfrågningar om bygglov och detaljplanering. Dessa förfrågningar rör alla bebyggelse av småhus. Nötbolandet är ett kuperat landskap och tillsammans med dess övriga förutsättningar ligger teorier om terränganpassning för småhusområden till grund för själva planförslaget. Detta förslag anger till att börja med vilka områden som går att bebygga och sedan hur dessa delområden bör utformas. Längst bort i Nötbolandet, vid den östra stranden, äger kommunen själv mark som dess tjänstemän funderar på hur den kan exploateras. Examensarbetet tar därför även ställning till om och i så fall hur detta område bör exploateras. En idé om att bygga ett nytt sommarstugeområde, utform-at som ett traditionellt fiskeläge, test-as i detta område, utifrån analyser utförda vid befintliga fiskelägen..

This bachelor?s degree thesis was conducted in mechanical engineering at Halmstad University during spring semester 2010 in close collaboration with the company Gremo AB, located in Ätran, Sweden. Gremo AB produces, developes and sales forest machines in both Sweden and on the international market.Gremo AB belongs to one of the market leaders in forest industry, especially with their forwarder. In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.

In 1999 the Swedish Parliament decided about 15 environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values.

This thesis investigates lacks in today?s use of the ERP-system Mapaz Affärssystem inthe production planning at Solna Pressgjuteri, and possible improvements. Today thedates calculated by the program to plan the orders are inaccurate and the ordersequence is not optimal, and therefore continuous manual corrections are needed.The approach was to study the program Mapaz to understand how it works, andidentify available parameters for input and output in the different tools offered in theprogram. By studying old lists of planned orders and relevant parameters in Mapaz forindividual orders, production groups, products and operations, the connectionbetween input and output parameters could be understood.Participating in planning meetings and discussions with the company behind theERP-system identified the current usage, desideratum and possibilities with theavailable tools. These were then matched to describe the reasons to the insufficientplanning and form possible actions for improvement.The work has showed poor understanding for the ERP-system and its functions, assome tools intended to assist the planning were not used, and some even usedincorrectly.

Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply. The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

In urban planning and design today interventions tend to take place in already existing areas and inevitably effect also surrounding areas. The many parties involved in any change leads to a demand for a shared language around these areas. This thesis aim to, through understanding and communicating a site, Stora Södergatan in Lund Sweden, inspire to a novel way of looking at an urban site preceding design- or planning interventions. Based on a theoretical framework where site is considered as a relational construct, material as well as immaterial, a framework for site thinking is constructed. Further, with theory of representation, the communication of the site is emphasized and accounted for as part of the framework.

The purpose of this paper is to examine how the revised Planning and Building Act (SFS 2010:900) have influenced the comprehensive planning in Swedish municipalities. A focus is directed at examining how the new law regulates a greater consideration to climate aspects and the what consequences this results in regarding the implementation of the law in Swedish municipalities comprehensive plans.The paper is a case study, containing both quantitative and qualitative methods. The case study is based on three municipal comprehensive plans. Based on quantitative material three municipalities have been selected to constitute the sample of this study. These municipalities are A?lvsbyn, Sollentuna and Olofstro?m.

Hammarkullen tillkom under slutet av 1960- talet och början av 1970. Området har formats av den tidens ideal med breda vägar och uppdelade funktioner. I Hammarkullen har få förändringar och förbättringar gjorts sedan det blev till. Genom att studera området, hur det ser ut idag, kvaliteter och brister, samt genom analyser har jag valt att främst fokuserat mitt arbete på: ? komplettering av bebyggelse ? utveckling av den yttre miljön ? utveckling av torget Huvuddelen i mitt examensarbete ligger i planförslaget.

Ett samhälle där en hög andel av transporterna sker på cykel har många fördelar för miljön, hälsan och ekonomin. Inom staden har cykeln även fördelen att den tar lite utrymme i anspråk och kan bidra till en attraktivare stadsmiljö. Syftet med detta arbete är att presentera åtgärder som ger förutsättning för en ökad och säker cykeltrafik. Baserat på svenska och utländska riktlinjer samt exempel från städer med en hög cykelandel ges en överblick över olika sätt att främja cykling i staden. Det handlar om att inkludera cykelplanering i övriga stadsplaneprocesser, att skapa strategier för stadens utveckling av cykling, att satsa på fysisk infrastruktur anpassad efter cyklisters behov och att informera och följa upp de mål som sätts.

This plan of multiple-use is made on the private owned forestproperty Äspinge 2:2 in the middle of Skåne. The term ?multiple-use? came to Sweden in the beginning of the twentieth century and has slowly grown until about 30 years ago when the laws of nature conservation and sustainability was written into the forest law. The so called ecoturism got more and more popular and people began to seek space and silence in difference to the life in the highly populated areas. This also encouraged foreign tourists to come to Sweden. Mostly danish, german, and dutch people.

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Water related problems are highlighted as a challenge to sustainable development and the topic of forests and water is gaining increased attention worldwide. Governing forest and water is a complex issue, as the interactions are affected by policies and actors from multiple levels and sectors. In Sweden, forests cover much of the land and forestry is an important land-use, inevitably impacting the water in the landscape. This study aims to understand and explain the existing governance framework around forestry and water in Sweden. Based on the Policy Arrangement Approach, the study?s research questions focused on the actors involved, the formal and informal rules, the resources and power structures and the discourses related to forestry and water in Sweden.
