Enkätundersökning hos markägare inom SCA Skog Ångermanlands Skogsförvaltning

This report is a joint venture with SCA Forest, Ångermanlands forest man-agement area. The purpose of the study is that SCA Forest wants to know what the landowners in Ångermanlands forest management area think about SCA Forest and who they deliver their Timber to. SCA Forest is the largest private landowner in Europe, with an area of about 2.6 million hectares. Today, SCA offers lumber, wood products, tis-sue and packaging and has factories all over the world. SCA Forest has five forest management areas in the north of Sweden, with the headquarters in Sundsvall. A questionnaire was sent to 265 landowners, where they had to answer 15 questions with possibilities to give comments. The survey was sent out on 21 of February with a response requested by 3 of March 125 landowners responded to the survey, giving a response rate of 47%.

Alla vill beta men ingen vill bränna : skogshistoria inom Särna-Idre besparingsskog i nordvästra Dalarna

In this work I have tried to reconstruct the forest history within Särna-Idre forest common in northern Dalarna from the 19th century until present time. The Särna-Idre region has been an extensively used landscape for a long time. Pollen which indicates grazing has been found in samples orginating from the 10th century. Early travellers from the 18th and 19th centuries seem to have been passing trough a "used" landscape. Burned forests on naked ground are described as common. Also large areas are mentioned as undisturbed with lots of large trees, snags and dead wood.

Hårdgörning av Asp

Hårdgörning av trä syftar till att göra materialet hårdare. Detta går att åstadkomma genom komprimering, det komprimerade materialet tenderar dock att återgå mot sin ursprungsform då materialet utsätts för fukt om ingen låsning sker. Låsningen kan ske mekaniskt i en treskiktskonstruktion som motverkar träets fuktrörelser. Dessa skivor har dock visat sig vara instabila och tidigare försök har uppvisat deformationer i form av kupning. Denna undersökning syftar till att utreda förutsättningarna för att använda komprimerad asp samt att ta fram underlag för framtagning av en kommersiell produkt.Praktiska tester har genomförts för att studera hårdhet, återfjädring och densitet hos det komprimerade virket.

Industrialiserat byggande : Fältfabrikens användning, utveckling och framtid

The construction industry is currently receiving much criticism for inefficiency and slow development while demands for reduced built in moisture and efficiency increases. This report examines whether the use of field factories can meet these requirements and what factors that will be critical for future use of field factories. Industrialized construction with field factory is compared with traditional loose Timber construction and industrial construction in the fields of execution, logistics and working environment. The aim of this report is to provide a basis for field factories current and future use and development. To achieve the aim of the report, people with experience in the use of the various methods was interviewed and literature studies in the various fields done.

"Anders Andersson hade eld i sin tjärdal" : en analys av Jonas Åströms dagböcker 1868-1891

"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891 Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.

Data retrieved from airborne laser scanning represents a new source of forest data. Today, the technology has matured so that it can function in an operational environment. The aim of this study was to compile areas of application of laserdata in forestry. Moreover to analyze costs and accessibility of laserdata. The goal was to provide private forest owners information to support assessments of possible benefits of laserdata.

Argument för prissättning av skogsfastigheter

The world economy of today is in an extensive financial crisis which has lead to the fact that people seek well placed investments and securing of capital, something that by many people can be found in forest investment. The price of forest estates has increased with 90 % during the last 5 years and marketing polls indicate a positive belief in the future among forest owners. The development of Timber prices has not increased to the same extent as the forest property prices which implies that the property price not only reflect the yield value from the forest but also that the lumber value does not have such a meaningful role in the pricing of forest properties as proven earlier. This fact means that forest owners either invest their capital in forest in a speculative point of view or that the purchasers of forest properties invests in non monetary benefits that lacks a direct yield value. The purpose with this degree thesis is to increase the understanding of the pricing of forest properties with focus on the above mentioned fact.

Erfarenheter av uppföljning efter gallring och föryngringsavverkning för att nå kraven i miljöcertifieringssystemen FSC och PEFC

Miljöcertifieringssystemen PEFC och FSC ställer krav på uppföljning och revision för att säkerställa att kraven och kvalitén uppnås. Studiens syfte var att belysa de skogliga maskinentreprenörerna och förvaltarnas/virkesinköparnas erfarenheter av arbete med uppföljning inom miljöcertifierat skogsbruk. Materialet insamlades genom telefonintervjuer och analyserades med kvalitativ innehållsanalys, vilket ledde fram till resultatet. Uppföljningen och traktdirektivet har en viktig roll för att nå miljöcertifieringarnas krav. Dialog och delaktighet mellan de olika yrkesgrupperna var viktig, enligt respondenterna, för att miljöcertifieringen ska nå en hög kvalité och för att skapa engagemang och vilja att förbättra arbetet..

Laserdata i skogsbruket : - och möjliga tillämpningar för privata skogsägare

Massivträ : Jämförelse mellan olika principer för sammanfogning av trä till plattelement med avseende på pris, hållfasthet och ekologi

Ökad användning av byggtekniken massivträ kan ge ett positivt bidrag till hållbart byggande. Utvecklingen inom datornavigerad bearbetning ger massivträ möjligheten att rationalisera byggproduktionen inom trä. Tekniken ligger rätt i tiden och kommer att värderas allt högre då den tillvaratar materialets karaktäristiska egenskaper.Utvecklingen av massivträ har resulterat i teknikvarianter av hur virke kan sammanfogas till solida element. Ett behov har funnits av en marknadsjämförelse mellan befintliga principer där studien förtydligar grundläggande skillnader för intresserade byggaktörer. Problemfrågan för denna studie har varit: vilka principer för sammanfogning av trä till plattelement inom massivträ är mest fördelaktiga? Detta sett utifrån faktorerna produktionskostnad, hållfasthet och ekologiska övervägningar.För att förtydliga den undersökta byggmetodens nytta i ett vidare perspektiv har det presenterats en allmän beskrivning av massivträ.

Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

Föroreningar orsakade av stenar inblandade i barrmassaved

Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.

Marknadsundersökning för SCA Skog AB avseende utbor i Mälardalen :

The need of raw material does of course fluctuate but the long term view is an increasing demand due to the growing consumption of sawn Timber products, pulp, paper and lately also biomass. This has led to a keener competition for wood. At the same time there is an ongoing structural change of a significant part in the Swedish wood supply market, the private forest owners. In 1992, 22 % of Sweden´s 335 000 private forest owner lived apart from their forest. In 2007 this figure had risen to 36 %.

Vad vet gymnasieelever om betygskriterierna och kursplanen i Idrott och Hälsa?

The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.

Volymsrapportering vid drivningsarbete

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.
