Att bygga en stamdatabas för gotländsk tall
Today's Swedish large-scale forestry uses almost exclusively computer-aided bucking. It allows the harvester computer, using an optimisation price list (steering price list), to maximize the value of each tree. The optimisation price list can be adjusted so that the industry gets the raw material it demands from the forest.
There are various simulation programs that can be used when constructing a optimisation price list. The simulation program merchandise a database of stem shapes using a given price list and mimics a harvester's work. To get the demanded raw material for the industry it is important to use a well-adjusted optimisation price list.
Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd
The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.
Från nytta till nöje : allemansrätten i den svenska skogen
This essay intends to provide an understanding of the developments in the right of public access and recreational activities in the forests of Sweden, and which factors and prerequisites that have affected this development. The forest and its history, along with recreational development has in many ways shaped today?s rights of public access, but there is also an age-old tradition of public access that has affected how we have used the forest, and that also has enabled the development of outdoor recreation. Many are unaware of this, which causes misunderstanding to appear around the rights of public access and how it is supposed to be used.The essay opens with historical descriptions of public access, the Swedish forest and outdoor recreation, to thereby provide a picture of how these three fields have influenced each other over the centuries. This is followed by a description of the current access rights and the problems associated with those, and a description of other countries' equivalent of the right of public access.

Metod för kartläggning av lövråvara i Södra Skogs verksamhetsområde
Södra Skog chose in 2011 to convert the saw mill in Traryd to a gradually refined sawmill of hardwood. In 2009, they had also acquired the hardwood sawmill in Djursdala. This was strategically important for Södra's business since the demand for hardwood products has increased. The standing volume of deciduous trees in Sweden is today approximately 524 million m3sk and it has increased rapidly in recent years. However, the deciduous forests are to a large extent located in areas that are set aside for nature conservation and is thus not available to the industry.The goal of this work is to create a simple and reliable method for mapping of deciduous wood volumes in areas where Södra Skog is operating (Götaland excluding Gotland).The material that is used is raster databases with estimated forest attributes (kNN-Sweden), data from National Forest Inventory (NFI) and forest management plans.
Privata skogsägares inställning till frivilliga naturvårdsavsättningar samt kvalitets- och tillväxthöjande skogsskötselåtgärder :
The business mission of Norra Skogsägarna is to achieve a profitable forestry for the private forest owners. With this as a background it is of interest for the forest owner association to know how forest owners think about voluntary retentions, the methods of increasing production and quality and if there are differences between those who have chosen to certify their forest and those who haven?t. This kind of knowledge is of importance, to in an effectively and adjusted way, help the forest owners achieve a profitable forestry.
The objective of this master thesis is to increase knowledge about private forest owners? opinions of the methods of increasing production and quality and to what extent these methods are used.
Kvinnliga virkesköpare inom Holmen Skog
Holmen Skog has only five out of 70 wood buyers who are women, This report is seen as a step in the process towards gender balance in the company. This is a problem that is equal over the entire forest industry in Sweden. They all think that sexual equal workplaces are very important to remain competitive, see things from different perspectives and development of the company.
The survey was done by sending out questionnaires to all women who work and have worked as a wood buyer at Holmen, and as many men of both categories. These four categories became a total of twenty persons. To map the industry another questionnaire was sent out to the six largest forest companies in Sweden.
The survey found that female wood buyers not finished their work earlier than men did, as they thought before.
Det enskilda trädet som meningsbärare : erfarenheter av två trädplanteringsprojekt i Helsingborg
Individual trees can act as carriers of meaning. When a person attributes deep meanings to a specific tree, a relationship between the person and the tree is created. To avoid conflicts between users and planners, increased awareness is required of how important individual trees may be to a person. The objective of this study was to elucidate persons? relationships with individual urban trees.
Design Program for Dessie Campus, Wollo University, Ethiopia
A geographical position and its social, cultural and political context as well as climate
and specific physical characteristics define the scope for a landscape design project.
This has become clearer for us in our master project where we have made a Design
Program for the outdoor environment of Wollo University in Dessie, Ethiopia and
analysed and reflected on the work and process. The aim for the project has been
to design an attractive and functional outdoor environment for the Campus, based
on the inventories and the needs and wishes of clients and users. But, the aim has
also been for us as landscape architect students to gain a greater knowledge about
landscape architecture and the design process by position ourselves outside our usual
context. The method has been open and seeking where the site, literature studies,
dialogues with people and our own experiences from the field study in Ethiopia has
influenced the work.
Wollo University is situated 400 kilometers north of Addis Ababa, in a
mountainous landscape. It faces problems of heavy rainfall during the summer,
soil erosion, a lack of essential facilities, and is still a construction site with empty
spaces in-between buildings and infrastructure.
Tätortsnära skogsrekreation : fallet Mösseberg i Falköpings kommun
Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.
Marknaden för skogsvårdstjänster : en undersökning bland privata markägare inom en region i Värmland
This work broadly illuminates the conditions for increasing the commissions of forestry services within the whole, or parts of, the western regions of Stora Enso?s operating area. Through a questionnaire, a survey was made examining whether the owners of the forests themselves do the forestry on their woodlands. This foremost concerns the pre-commercial thinning, but also planting and soil scarification. The survey also shows who are buying the most part of their forestry services and who are carrying it out themselves.
Skötselförslag på utvalda nyckelbiotoper i Kalmar och Kronobergs län.
The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.
Vart är naturen i skärgården på väg? : skogshistoria på Ängsön-Marskär i Stockholms södra skärgård
The following thesis is a study of the forest history on the island of Ängsön-Marskär concentrating on the last three hundred years. The island is located in the administrative province of Stockholm, the local community of Haninge and it is situated approximately seven kilometres east of the island Ornö in the south of the Stockholm archipelago. The questions this thesis attempts to answer are: How where the natural resources on Ängsön-Marskär used through the centuries? How has the state of the forests developed since the 16th century? How will the nature develop onwards? The thesis is based on archival sources for Ängsön-Marskär and the surrounding areas. A field study was conducted where the entire island was investigated using an objective forest inventory method.
The first map material existing over Ängsön-Marskär is from the year 1711.
The Swedish forest industries' view on the future market potential of nanocellulose
General concerns about environmental issues may mean that the demand for bio-based products will increase. Opportunities that arise on markets, together with the declining demand for newsprint, may trigger firms in the Swedish forest industry to increase their development of new products. One product that has received a lot of attention during recent years (and is a contender) is nanocellulose.
The purpose of this master thesis was to examine the Swedish forest industry?s view on the market potential of nanocellulose.
Trädföryngring i låga gropar uppkomna vid brand i boreal naturskog :
This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees.
In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.
