Naturhänsyn på slutavverkade hyggen i Östergötlands län.

95% of the productive forest land in Sweden are now being exploited for forestry. The new Forestry Act of 1993 equate the goal of production and the environmental goal which means that the objective for forestry is a sustainable yield, while the biological diversity must be preserved. Recent years results from the inventories of the Board of Forestry show declining trends in how nature conservation aspects taken into consideration at the felling sites.The aim of this study is to investigate what happends with the nature consideration taken at felling sites in the long run. 20 final fellings in the county of Östergötland were re-inventoried 7-9 years after final felling. These felling sites had previously been inventoried before final felling (P0) and one year after final felling (P1) in the inventory Polytax by the Board of Forestry.

Change or die Bilden av folkbiblioteket i den nationella bibliotekspolitiken i Sverige och Danmark utifrån teorier om det postmoderna samhället.

The aim of this Masters thesis is to investigate how the image of the Public library is described in the Swedish national library politics, and compare it with the image given of the public library in the Danish national library politics. The method used for this analysis is a comparative discourse analysis of the homepages produced by the Swedish central government Regeringen and Kulturrådet and its Danish counterpart Kulturministeriet and Biblioteksstyrelsen. Theories on postmodernity have been used to analyze how the Swedish and the Danish central governments image of the Public library corresponds with a changing society and the changing behaviour of the public library users. Our analysis concludes that the traditional view of the Public library as an institution mainly concerned with literature and reading still is of great significance in the discourse of the Swedish central government. In contrast, the Danish central government presents a more postmodern view of the public library as an institution that is part of the Information- and the Knowledge society.

Echoing nature - A design of an exhibition concept based on a natural phenomenon as a model to explore and learn

In the project Echoing Nature i have searched a design for an exhibi¬tion concept. That visualizes the natural phenomenon of self-assem¬bling materials in a simplified way. My question is, how can you emo¬tionally re-connect the modern man to nature and raise awareness. I assume my thesis that the experience of a natural phenomenon can inspire us to see a bigger context, provoke curiosity and generate an initial sense of belonging to nature. The result is an interactive sculp¬ture that consists of 3-dimensional Tetris blocks.

Natura 2000-områden: rättsverkningar i jämförelse med vanliga naturreservat

Syftet med uppsatsen, att utreda de skillnader i rättsverkningar som finns mellan Natura 2000-områden och vanliga naturreservat,har jag uppnått genom att använda mig av traditionell juridisk metod. Genom att jämföra lagtextformuleringar, förarbeten och bakgrund till bestämmelserna om de två områdesskydden har jag funnit att reglerna om Natura 2000-områden har en betydligt större räckvidd än bestämmelserna för vanliga naturreservat. Allehanda verksamheter och åtgärder omfattas av den särskilda tillståndprövning som gäller för ingrepp i Natura 2000-områden, medan vanliga naturreservat har begränsad räckvidd till de ingrepp som stadgas i reservatsföreskrifterna. Jag har även funnit skillnader när det gäller inrättandet och upphävandet av områdesskydd, och resultatet är att EU-kommissionen utövar en stark kontroll vad gäller Natura 2000-områden. Kommissionen kan tvinga medlemsstaterna att inrätta särskilt skyddat område, och om medlemsstaten vill upphäva skyddet måste samråd ske med kommissionen.

Åtgärder för biologisk mångfald i parker : Fallstudier i Botkyrka, Haninge och Nynäshamn

Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.

Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Threats and opportunities for the survival of the Yangtze finless porpoise

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

Selånger deltapark : Sundsvalls nya stadspark - en vision

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.

Nationellt uppdrag och internationellt samarbete ? Nationalbibliotekens bevarandemetadata för digitalt skapat material

The National Libraries task to save and preserve the national cultural heritage has turned to a new challenge in a digital world. The preservation of born-digital material for future use requires not only saving the digital object itself but also information about the object, preservation metadata. This is a relatively new issue and the library community has very little experience in this area. It has become evident that international cooperation is necessary to solve the task and that the development of international standards is of fundamental significance. This thesis investigates what has been done to meet the problems with the fast obsolescence of digital material with the focus on metadata.

Aktiviteten hos thymidinkinas 1 i serum från hundar med juvertumörer och malignt lymfom

With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.

Qualities and supply of suitable dead wood for Ceruchus chrysomelinus and its dispersal pattern in a translocated population

The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.

Konflikten mellan bevarandekrav och tilläggsisolering : The conflict between conservation requirements and additional insulation

Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.

Svartedalens naturreservat : en social rikedom värd att utveckla!

Svartedalens nature reserve a social richness worth develop. The nature reserve of Svartedalen is an area of high biological and social values. The reserve is located close to several densely populated areas. The reserve has been classified as a national area of interest for nature conservation and outdoor life, and as a Natura 2000 area according to both the bird- and habitat directions. The reserve is the largest landarea in Västra Götaland, 3 410 hectares, where a resolution has been made about all these forms of protection. The foundation Skogssällskapet owns 1 956 hectares of the reserve, at 1 384 hectares of the property they pursue FSC-certified silver culture, according to current management plan.
