Examining the social component of sustainable forest management in Prince Albert and Vilhelmina Model Forests
Due to the forest industry downsizing, many communities in rural forest regions in Canada
and Sweden are facing problems to survive. In order to create community sustainability,
resilience and well-being in remote forest regions, the view on the forest resources has
shifted towards multiple use, through the concept of sustainable forest management (SFM).
Beside the economic and ecological elements of sustainability, the social forest values are
needed, contributing to the human well-being, local participation, stakeholder collaboration,
human rights and cultural connection.
In this thesis the embodiment of the social component of SFM within Prince Albert Model
Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners
and facing similar challenges as rural boreal forest regions, the two model forests are compared
through analysis of projects and activities, conducted interviews and organization
documents.
Looking at projects mentioned as successful by the interviewees, they all have elements
from the social values of SFM. The direction can be explained by the introduction of the
Forest Communities Program in Canada, demanding the Model Forests to work towards
community stability and resilience, the Model Forest organization concept itself and the
way global focus are increasing around social forest values. In the future, it may be important
that the role of the MFs enable some kind of political authorization and legitimacy in
order to improve conflict solving and indigenous rights equality.
Nyckelbiotoper och kontinuitetsskog i Vilhelmina Kommun : ett landskapsperspektiv
Med nuvarande trend kommer snart all skog bortsett från de skyddade områdena att vara påverkade av trakthyggesbruk. Denna studie inom Vilhelmina kommun och Vilhelmina Model Forest visar hur skogslandskapet i sydöstra delen av Vilhelmina har påverkats sedan trakthyggesbruket infördes, med störst påverkan i den sydöstra delen och minst i den västra delen närmast fjällkedjan. Detta arbete har syftat till att analysera hur skogar som inte blivit brukade med trakthyggesbruk och nyckelbiotoper är fördelade geografiskt, och hur de sammanfaller geografiskt, inom ett stort landskapsavsnitt i den sydöstra delen av Vilhelmina kommun. Studien har också syftat till att visa om storleken på skogsområden med sammanhängande opåverkad skog har betydelse för antal och areal registrerade nyckelbiotoper och om det finns någon trend från sydöst till väst. Alla analyser för arbetet har skett i ArcGIS med hjälp av kartmaterial av registrerade nyckelbiotoper och kalavverkade skogar från Vilhelmina Model Forest.
Resultatet visade att 63 % av arealen nyckelbiotop i den sydöstra delen av kommunen ligger i skog som inte blivit genomhuggen med trakthyggesbruk.
Markanvändning och ekosystemtjänster i en gradient från borealt till alpint landskap ? Vilhelmina Model Forest
Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.
Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :
Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.
Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.
The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..
Realisering av en modulär skogsmaskin - En skalmodell
Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.
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%.
Hur väl skogsägare följer åtgärdsförslagen i skogsbruksplanen : en enkätundersökning
This rapport is about how often private forest owners follow the measures proposed in their forest management plan. The survey is made in cooperation with the forest-owners association Norrskog.
The private forest owners are relatively satisfied with the forest management plans and with the measures proposed. There are some differences between those who live on or near their property and those who live many miles away.
The forest owners who live on their property are those who follow the proposed measure of precommercial thinning to the largest extent. That group also values precommercially thinned stands higher than thinned stands.
The complete opposite is the case for the group that lives far away from their property.
Almost all of the respondents thought that the forest management plan would be or had been a good help in the decision making about the forest..
Enkätundersökning om skogsägare inom Norrskogs upptagningsområde
The purpose of this report is to find out what different preferences forest owners have in the region where Norrskog have their operation area, what they prefer and think about Norrskog. The purpose is also to compare some of the questions to a similar study that was made in 2008.
The study is made in cooperation with Norrskog which is a forest owner cooperative. Norrskog has about 13 000 members which is about half of all forest owners in the region.
To get the answers from the forest owners, questionnaires were sent out by mail. 371 were sent out and 102 came back. There were more members of Norrskog that responded than it was nonmembers.
The results indicate that the forest owners have long term perspectives, their priorities are to nurse the forest so they can get the profit later on.
Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning
Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.
Strategic forest planning using AHP and TOPSIS in participatory environments : a case study conducted in Vilhelmina, Sweden
When a decision is to be made on what long term strategic forest management plan to use, consideration must often be taken to multiple objectives. Such decisions are very complex and a promising approach to handle them is by Multiple Criteria Decision Analyses (MCDA). The study is based on the problem that the MCDA that have been implemented into forest management planning have only had capacity to compare and evaluate a limited number of management plans; which means that there is a risk the most suitable plan is missed. The aim with this study was to test the applicability of combining the MCDA tools: the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and the Analytic Hierarchy Process (AHP) for including consideration to multi-objectives into strategic forest management planning. The study was based on the process of creating and selecting a management plan, using Heureka PlanWise, suitable for all the major objectives found in the forest holdings of a municipality in northern Sweden.
Processbeskrivning av Rundvirkestransport : En Fallstudie hos Tra?frakt Go?taland AB
Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.

Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet
This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.
