Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :

Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.

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 %.

Tillvaratagande av GROT i skärgårdsnära miljö :

The main aim of this study was to investigate and compare different methods for the extraction of forest fuel from environments close to an archipelago. The study was based on relevant literature and published reports as well as personal communications. Forestry has traditionally been characterized by intense efforts to rationalize and mechanize the cutting technique used for timber and pulpwood. In line with the increasing importance of forestry, more concentrated efforts can be expected in the area of techniques and methods, especially for the above-mentioned product lines. In Sweden, forestry is of major importance and the Swedish economy and standard of living have mainly been created based on the revenues generated from it. Thus, it is vital that Swedish forests are harvested in an efficient and responsible manner. The demand for biofuel is growing and today accounts for 15% of total Swedish energy production, a share that will probably increase. This study is based on three research questions, which are described under the heading of Aim. The results reveal that the most profitable method for handling forest fuel is the traditional one, which is also the most commonly used method in southern Sweden, namely the stockpiling of logs in a clearing by means of forwarders followed by splintering at the place from where they will be distributed. Today, the high cost of barge transport required for the extraction of forest fuel in an archipelago environment renders such operations unprofitable.

Klippning i klena gallringar : prestationsstudie av Forest ebeaver

Forest ebeaver is, equipped as a bio-energy harvester, approximately four and a half meter long and weigh just over two tons. The main purpose of this report is to find out whether a small machine like Forest ebeaver can be profitable used in early thinning. To find this out a study has been made using the machine to thin in a young pine stand..

Betydelsen av skogsbruksplaner som verktyg vid anskaffning av virke

Forest management plans have been sold to private forest owners by wood supplying companies for a long time. These plans are considered to be effi-cient tools to identify measures and wood volumes, and are simply a starting point for discussions between private forest owners and round wood pur-chasers. However, large variations are observed between different purchas-ers, in their usage of the plans. The purpose of this report is to identify to what extent a forest management plan can promote an increase in the amount of wood which a round wood purchaser can obtain and to find differences in the way of using the plans between different wood purchasers. Furthermore, the purpose is also to ana-lyse if varying owner structures can be underlie variations in the selling of forest management plans. Qualitative interviews with nine of Stora Enso?s round wood purchasers were performed.

Civil-militära relationer i komplexa fredsinsatser ? ett organisationsperspektiv

The response to many on-going or emerging conflicts since the beginning of the 21st century has been different forms of multinational complex peace operations. Civil-military relations are a commonly studied field that traditionally has its focus on nations. This study intends, in the context of organisations, to test the correlation between a civil-military approach and outcome in complex peace operations. A hypothesis has been deduced from researcher Robert Egnell?s theory on complex peace operations, that states that: UN peace operations with an integrated civil-military approach are more successful in achieving their goals than peace operations with a divided approach.

Marknadsundersökning av Södra skogsägarnas medlemmar inom Gislaveds verksamhetsområde

This study is done on behalf of Södra skogsägarna in the autumn of 2012. The main purpose of the study is to get an explanation to why some of the members are passive in their forestry, and how Södra can stimulate them to become more active. To achieve this a questionnaire study was conducted on the members of Södra in the community of Gislaved. The result of the study shows that there are many different factors that influence whether the forest owner is active or not. Examples of those factors are timber prices, the forest owner's objectives and the forest owner's financial situation. The main goal for the forest owners in the survey was to obtain high economic result and to increase the standing timber volume for the next generation.

Generell hänsyn vid avverkning : påverkan av dispens från sexveckorsregeln samt skogsägares kunskap, tankar och åsikter

The forests in Sweden have, for a long time, been managed intensively. This has led to even-aged stands with few tree species and a lack of dead wood. Therefore, general conservation measures in connection with regeneration felling are important in order to promote biodiversity. Inventories carried out by the Swedish Forest Agency, however, show that about 25 % of the felled area does not reach the level of the Forestry Act, regarding general conservation measures. The aim of my study was to see whether exemptions from the six week notice of reporting regeneration fellings (the Forest Agency demands a report six weeks in advance of fellings), affect the results of the general conservation measures taken.

Enkätundersökning hos skogsägare inom SCA Skog Norrbottens Förvaltningsområde

This report has been done in collaboration with SCA Skog, Norrbottens Forest Management Area. The purpose of the survey is to try to find out what the forest owners who either live in Norrbottens Forest Management area or outside but has their forest holdings in the administrative area has the vision of SCA Forest and their forest services offered by the administration. But also to find out the presences of other timber buying players who procures timber in the administrative area. This study seeks to determine if there are deficiencies that may need changes or improvements to the prevailing conditions in Norrbottens management area. The literature study is about how to design a questionnaire based on what you want to know and what to consider in order to eliminate the problem of constructing a questionnaire. A questionnaire was sent to 400 randomly selected forest owners who have their forest holdings within SCA Forest Norrbotten Management Area. And of the 400, it was 181 respondents with 39 women and 138 men.

Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning

Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in Forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory. The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method. The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking. The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.

Lika, Olika? : en materiell studie av skogsfinska bosättningar i Sverige

The main purpose of this essay is to examine if it is possible to identify farms of ?forest Finnish? people in Sweden, by means of an archaeological analysis, comparing the forest Finnish settlement with known none-forest Finnish settlements. This study is based on material excavated from the farms of Grannäs, and Råsjö, in the Swedish provinces of Jämtland and Medelpad. Both farms are dated to the 17th and 18th century. The study itself is divided into three parts, firstly a general study to get an overview of the material, secondly a study of ceramics as an attempt to discern social status and lastly a study of the animal bone material for analyzing the forest Finns? livestock and possible hunting habits.

A Swedish national forest programme ? participation and international agreements

Sweden is in the initial phase of forming a national forest programme (nfp). The establishment of an nfp has been evoked by international policy developments and a national debate questioning Swedish forestry and forest policy. National forest programmes are participatory processes for the development and implementation of forest-related policies and international commitments. Hence, the aim of this master thesis is to assess the stakeholders? acceptance of participation and integration of international issues within the Swedish national forest programme.

Hållbart skogsbruk och naturvård ? ett skogsägarperspektiv

The Swedish government has set up 16 environmental goals for Sweden to achieve. One ofthem is ?Living forests?, which is the foundation for the ?National strategy for the formalprotection of forests?. The ?National strategy? puts the private forest owner at the centre ofattention in order to achieve the environmental goal ?Living forests?.
