Uppfölining av naturvårdande skötselåtgärder(NS) i ekopark Storklinten
This study's primary purpose was monitoring of conservancy operation measures. The fixed sections within ekopark Storklinten owned by the forest company Sveaskog. These measures are performed with the purpose of creating and maintaining hardwood forest and mimic natural processes. The sections were divided into different categories depending on the type of measures they were exposed with. The monitoring showed that the purpose of these measures was fulfilled in general.
Svenska hushålls vedarbete : en fallstudie i Umeåregionen
In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood.
The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.
Släktöverlåtelser av skog och jord i två byar i Sverige
The way to acquire forest in Sweden from parents has been unequal, men were prioritized over women, which was the traditional inheritance pattern. Research has made this clearer by using gender, which ?values? our stereotypes of sexes and can help us understand inheritance patterns. The gender determined who would inherit but also the form of ownership, praxis, property rights, regulations, power and work invested made by a sibling could influence. The purpose with my study was to find what conditions governed inheritance of forest on the properties I investigated and what influence gender had.
Hur bokskogslagen blev till ? konflikter och lösningar 1964-1974
During the early Middle Ages beech forests (Fagus sylvatica L.) spread out over large parts of southern Sweden. They had a crucial role in human survival for hundreds of years. For various reasons, the beech forest area has decreased since the 1600s. Spruce planted on former beech forest land was the primary reason for the decline during the second half of the 1900s, which made many worried about the future of the beech forests and led to a beech forest act in 1974. This study describes the background to the beech forest act based on parliamentary official documents.
Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel
Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management.
The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.
Utveckling av en effektmätare för landsvägscykling
Over 90% of forestry work is carried out today by contractors, thereforeclear agreements between the client and the contractor it is of utmostimportance. Contract Packages for work within the forest sector (APSE) is acollection contract templates that the industry jointly developed for thispurpose. The purpose of this thesis is to examine how forest contractors doto keep themselves updated of the current laws and government regulations,which channels are available to accomplish this and what possible obstaclesmay occur. 20 interviews were conducted with contractors engaged inlogging. The results show, among other things, the availability of and whichchannels most contractors use out of which aggravating circumstances existand how strong they are perceived and what is expected of the client in thisregard..
Betydelse av lövinslag, död ved och variation i träddiameter för artrikedomen hos småfåglar
Forest management contributes to the changes in forest structure by turning heterogenous forests of varied age into homogenous forests of similar age and thus affect bird species depending on different structures or habitats which are lost during forestry. In this report, a study was made to investigate how the amount of decidious trees, dead wood and variation in tree diameter affect bird diversity. The purpose of this study was to be able to give forest management guidelines to increase bird diversity. This study was conducted by investigating 65 transects in forests of different structure south of Linköping, Sweden. Along the 65 transects, birds were inventoried as well as the vegetation.
Vitberget Skellefteå, ett kommunägt tätortsnära skogsområde ? föreningarnas och allmänhetens syn på hur skogen bör skötas
The question is who should govern and administrate a municipality owned urban forest? Should societies and the public be invited to participatory planning, who are the interested parties, could they be treated like a group and what are their opinions on administration and management? The study is carried out in a municipal owned forest Vitberget Skellefteå that is widely used by associations and individuals for recreation and training.This has led to several discussions in the local media about the management of the forest, especially in connection to harvesting. The work undertaken here has been to identify who has any interest in the management of the area. After identifying the interested parties, a selection of the societies, schools and pre-schools that actively uses the area as well as random individuals met in the area was interviewed. The questions asked can be divided into six main groups:? Communication with the municipality?s managers for the area? Interference from other activities? Views on forest management? Views on nature conservation? The uniqueness of Vitberget? Development opportunitiesThe crucial factors identified as being needed to succeed in managing an urban forest are long-term administration, information and communication.
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.

Lokal logistikoptimering för ENA Energi i Enköping
The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A).
The main purpose with this report is to look at three questions:
1. How does the supply chain look today? From forest to industry.
2.
Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia
There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.
Kalkning och vitaliseringsgödsling : synpunkter från organisationer och myndigheter samtprivata markägare i Kronobergs län
The background for this thesis is that at the beginnings of 1980´s the National Board of Forest started an experiment of lime dressing to reduce acidification in forest soil and in ground water. The purposes of this report are to explain organization?s, government?s and private landowners viewpoint on lime dressing and vitalization fertilization, some socio-economic aspects are presented. The general conclusions are that the majority of the interested party?s are positive to vitalization fertilization but the forests owner?s in generally need much more information about this topic..
Förändringar i skogsbranschens organisation på 1990-talet : antalet tjänster, kompetens och utbildningsinsatser
In 1993 Sweden introduced a new Forest policy, with a larger freedom of action for the forest owners, but in the same time the forest owners are expected to take greater consideration of the forests and the environment, that is required by the law. This is necessary to be able to obtain the goals of the new policy. Therefore the demand for competence and guidance is larger than before. At the same period of time organisations where slimmed and trimmed during a economic recession and the question is how this has affected the number of employees on different levels in the organisations, the competence of the employees and their internal education and if these changes affects the possibility of implementing the forest policy.
This study contains three points in time where measures were made, 1990, 1995 and 2000.
