Naturhänsyn på certifierade privata skogsfastigheter : en jämförelse i praktiken mellan FSC och PEFC i Sydsverige
Nature conservation on certified small private forest owners- a comparison
between the two certification systems FSC and PEFC in southern Sweden
Today two different certification systems are used in Sweden to certify forest, FSC (Forest Stewardship Council) and PEFC (Pan European Forest Certification). During the last years certification of forests in general and different certification systems have frequently been debated. FSC is a globally widespread system and about 10 million ha out of 23 million ha Swedish forest is FSC-certified. The FSC-standard is mainly used by major forest companies and to some extent also by smaller private forest owners. PEFC is a European system and about 2 million ha Swedish forests is PEFC-certified today.
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 styr gruppcertifikatägarnas strategier vilka skogsägare som blir del av FSC-cerfifikaten?
This study investigates the relationship strategies the group Forest Stewardship Council (FSC) certification holder has with the forest owners. The (FSC) standard enables an organization to manage a group of forest management units under a single certificate, a process referred to as group certification.
Some certificate holders want a close relationship with the forest owner before they are offered to become part of their certificate. Other certificate holders have less strict demands on a close relationship with the forest owner before they are offered to become part of their certificate.
The study shows that it is in many ways desirable to have a close relationship between forest owner and group certification holder..
En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner
The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand.
The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted.
The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages.
The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent).
Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated.
Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same.
However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time.
If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..
Skogens produktionsvärden och dess betydelse för Sveriges ekonomi
The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.
Omfattning och differenser av gränshävder kontra registerkartan i Boda, Skellefteå kommun
The cadastral index map is a great benefit to the surveying and governments. The map's main purpose is to show how the overall cadastral division looks in Sweden. The lack of quality of the cadastral index map dose not allows property-owners to know where to draw the boundary between their and others' property. In order to know where to find the boundaries between two properties, is it up to the property-owners themselves (self or in company by the other property-owner) to construct various usucaption at the boundaries. The main objective of the study is to verify the existence and extent of usucaption on forest properties in Bodan, a village outside Skellefteå.
Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier
This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.
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.
Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?
Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.
The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores
To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.
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.
Binär matchning av bilder med hjälp av vektorer från deneuklidiska avståndstransformen
This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..
Mätning av stamdiameter med markstående scanner :
Booth for operational planning of harvesting and for long term planning, data is today collected manually. Intensive objective field inventories are usually too expensive. To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. The objective of this study was to validate how a terrestrial laser scanner could be used to measure stem diameter, and to test how the errors depend on distance from the scanner and tree species.
Two plots (one pine and one spruce) were used for this study.
Aspekter på flyttkostnader, fastighetsbildning och fastighetstorlekar :
This master thesis has three purposes. The first purpose is to give a theoretical background of how to divide up forest estates and to study how the legal system for these matters works.
A literature study has been carried out to give the background and a theoretical model has been made for analysing the law cases. The first purpose also partly touched the decision process in dividing up forest estates from point of view of the law of land parcelling (FBL), point of view.
The second purpose is to examine effects of a change of production requirements in 3 cap.7 § FBL as regards dividing up forest estates of private forest owners.
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.
