Trädens utveckling efter att de har lämnats som naturhänsyn : tillväxt, mortalitet och strukturell förändring 6-18 år efter avverkning

Today green tree retention, together with Leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

Omfattningen av icke avverkade områdeni samband med slutavverkning :

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.

Vallbrott med hjälp av grisar :

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

Whiplash : Preskription och adekvat kausalitet vid trafikolyckor

Whiplash is a bodily injury, where the person that is injured is subjected to force towards the neck, mainly in traffic accidents. Even low speed accidents can cause severe damage due to the complicated muscle and nerve structure of the neck. Symptoms range from neck aches and headaches to numb fingers and this makes the Whiplash injury difficult to diagnose. Whiplash is also a treacherous injury due to the fact that the symptoms can not be objectively verified. The principal symptom of the injury is pain, which is to its nature highly subjective.

Förslag till bebyggelse och park i kvarteret Seminariet i Uppsala

In the urban planning debate of today, two strategies for city development stand out as each other's opposites, urban sprawl and smart growth. This thesis concerns a development project of the latter kind and aims to give an alternative proposal to new buildings and a park in a Swedish city block. The term sprawl is used for new developments on virgin soil on the outskirts of cities leading to a city spreading, while smart growth stand for increased city density through development on re-used land within the city boundaries. The latter are often seen as more sustainable in many levels and are also shown to have positive effects on a number of city functions. At the same time smart growth has negative consequences on other aspects of the city such as public open spaces.

SKREA BACKE: Erfarenhetsåterföring och uppföljning av infrastrukturprojekt

AbstractThis report has been developed in cooperation with Peab Region Bostad Göteborg, mentor at Krook& Tjäder (through Chalmers), and examiner at Chalmers University of Technology. The report is the result of a research of a building project, constructed by Peab. The report is investigating and it means to identify and evaluate qualities in the dwelling and its surroundings. Its purpose is to evaluate how the residents in a chosen housing cooperative enjoy living there. It shall, with help of chosen quality aspects, identify what expectations the residents had before moving in, how they experience the dwelling and its surroundings today, and what hopes they have for the future planning of the area.

Vad påverkar skogsägarnas naturhänsyn vid föryngringsavverkning i region Mellannorrland? :

The objective of this thesis was to investigate what influence nature conservation measures taken at regeneration felling. Factors analysed were the forest owners´ situation and their characters, and information activities from wood-suppliers and the Regional Forest Board (RFB). The inventory was performed with a posted questionnaire followed up by telephone to forest owners and a posted questionnaire to wood-buyers. The forest owners were grouped in three strata, depending on the quality results (D- polytax inventory) of the taken forest conservation measures, and for this investigation forest owners were sampled from the population in the tree groups. In total 73 % (41/56) of the sampled forest owners answered the questionnaire Group A (17 answers): Good judgement Group B (19 answers): Bad judgement Group C (5 answers): This group was formed from the forest owners that were informed, by RFB, about nature conservation measures and culture history consideration before the regeneration cutting.

Att restaurera forna tiders beståndsstruktur : ett exempel från Jämtgaveln

In Sweden today so-called "prescribed nature conservation burning" is performed due to the change in silvicultural law, certification and an increased knowledge regarding the field of fire in the forest landscape. The aim is to re-create structures and qualities made by the fire regimes of the past, though on a much smaller geographical scale. The structures and qualities to be re-created are for example broad leaf stands, trees with large diameter, heterogeneous stands regarding variables such as age and diameter. If we increase our knowledge of the constitution of forests characterized by fire, then we will be able to set goals for what achievements to reach both on landscape scale and stand scale. The aim of this paper is to try to describe how a stand from the past was composed regarding mainly the spatial arrangement and compare it with the stand of today in the same place. This to be done by using relict material, that is stumps and dead standing trees.
