To make it easier for Forestry planning the forest owners needs data which describe characteristics of the forest. Such data you usually get from some type of inventory. A relatively new technology which probably is getting more important in the future, is laser scanning because of lower costs. But because the laser technology is relatively new you need to compare it with conventional inventory technologies to get better understanding of the possibilities the laser technology gives. This work intends to estimate field measured characteristics of the forest from laser data with help of regression analysis and then see which of the field measured properties that best could be estimated and which laser variables that gave the best results. This study shows that heights has the best estimates, but biomass, diameter and volume also gives good estimates.

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?.

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

The marketing strategies discussed in today?s literature are often developed for larger compa-nies and are therefore poorly fitted for smaller businesses with little resources, such as the small resort Enaforsholm Fjällgård in Jämtland. Hence, this paper focuses on presenting and discussing the marketing strategy storytelling and whether it is applicable to Enaforsholm Fjällgård. This mountain resort was given to the Royal Swedish Academy of Agriculture and Forestry (KSLA) in 1937 as a trust fund to be managed in the spirit of the grantor A.W. Bergsten.

This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

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.

Research on Stone Age hunters and gatherers in Norrland has been lively since the 1960s. Central to this research are questions about the organization of society, sedentariness, continuity and resource management. One central part of life in the taiga is the need for fire and fuel. This aspect has been little discussed in conjunction with the mentioned research questions. My goal is to show that the matter of fire and fuel is an important one that needs to be taken in to consideration when discussing Stone Age Norrland and hunter/gatherers.

FSC (Forest Stewardship Council) is the major form of certification system in Swedish Forestry today and its more than 11 million hectares are covering almost half of the total productive forest area in the country. Its regulations prescribe that at least 10 wind firm trees should be left behind after every clear cutting operation. This study have taken place on 30 recently clearcut objects in Bergslagen, Sweden, were an inventory of the standing stock have been made. The research shows that, with 90 % security, the retained trees together contain 9-13 m3sk per hectare. Pine is the dominant tree and it covers more than half the numbers of retained trees and its volume cover 65 % of the retained trees total volume. Spruce is on second place with 30 % of the retained trees, but only 21 % of the standing stock.

About a quarter of the Swedish land area is covered with shallow or thick peat. There is a potential to increase forest production in Sweden with almost 2 million m3/year in selected peatlands with low conservation values. This increase can be accomplished by drainage, complementary drainage, ditch maintenance operations and fertilization. The purpose of this study was to determine the level of knowledge regarding the management of forests on peatlands and was restricted to selected forest companies in Västerbotten County, with offices in Umeå. Three companies were chosen, SCA, Holmen and Norra Skogsägarna.

The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.

Bakgrund      Skogsmaskiner har under många år förstört både fornlämningar och gränsmärken. Idén till databasen/tjänsten uppkom av egna erfarenheter vid en förrättning, där flertalet gränsmärken hade blivit överkörda av skogsmaskiner. Syfte              Examensarbetets syfte är att lyfta fram en ny idé för att minska skadorna på fornlämningar och gränsmärken som skogsmaskiner orsakar, samt hur lägesnoggrannheten påverkar den nya tjänstens ändamål.Metod           Examensarbetet består av en litteraturstudie med syfte att besvara och ge en bakgrund till problemställningen. För att undersöka hur vanligt det är att lantmätare/mätingenjörer stöter på att gränsmärken blivit skadade av skogsmaskiner genomfördes en enkätundersökning. För en djupare inblick av lägesnoggrannheten på utrustningen i skogsmaskiner och vilken kvalitet på koordinaterna som krävs för en mer ändamålsenligt tjänst gjordes en intervjustudie.Slutsats         De uppgifter som finns tillängliga idag ska vara användbara när det gäller fornlämningar, för en ändamålsenlig tjänst som ska fungera ute i skogen där lägesnoggrannheten inte alltid är den bästa.

At the beginning of the 1970´s Forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

The work presented here aims to give the owners ofChâteau du Grand Val, Roland and Marie Nilssond?Aubigné an integrated creative forest management planin which their goals with the property is heeded, andwhere the plan is so clear that they can follow it withoutmuch difficulty.This work has come about through the normal processesof forest management plans, landscape architecturalproposals as well as through field trips, field andliterature studies, and our combined experience fromour studies. The study visits, both on location in Brittany,France, but also in other places, as for instance Högestad,has provided the background information that formedthe basis of our analysis and the proposal that is derived thereof. Some suggestions, which we consider importantto the overall impression of the property, is provided amore focused and detailed solution, while other parts,which are important but can either benefit from havingdynamics in the design process or will be adapted toadjacent sites, are developed using a more generalapproach. In some cases several possible developmentprinciples are presented.The proposal presents a detailed plan for themanagement of the forest from the experience, wildlifeand Forestry economic standpoint.

This report is the result of a project in the course Independent Projekt in Molecular Biotechnology at Uppsala University during the spring of 2014. The foremost purpose of the course is to give students the opportunity to carry through exstensive work in a project environment. This project was formed based on a comission from the biotechnology company SweTree Technologies, and the goal has been to compose a summary of the different techniques and methods that exist in the field of mass propagation of trees through the method of somatic embryogenesis.The project group has obtained information about the area mainly throgh reading patents, trying to find key components and bottlenecks in other companies? somatic embryogenesis technologies. This paper is divided into different sections, containing the patents of the automation of different steps in the process.

The purpose of this study was to examine how small-scale private forest ownersmake decisions regarding pre-commercial thinning. In 2015 it is ten years agosince the storm Gudrun hit the southern parts of Sweden and now large areas arein need of pre-commercial thinning. This study is built upon qualitativeinterviews with seven small-scale private forest owners with forest properties inthe county Kronoberg. The respondents were chosen by the modelSKOGSÄGARPROFILENTM (forest owner profile).The results of the interviews showed that five categories: ownership, the stormGudrun´s impact, silviculture, Forestry contacts and driving force was important.How will their purpose and aim affect the pre-commercial thinning? Personalinterests, and expectations of the next generation to take over, are purposes thisstudy has found.
