Uppsatsen behandlar felbegreppets tillämpning på skogsplantor. Lagstiftningen inom området skog och skogsplantor är relativt omfattande men skogsplantor är biologiska produkter varför lagstiftning inte helt kan förhindra att skador eller sjukdomar ändå uppstår. Det är helt enkelt inte möjligt att framställa skogplantor utan att en viss andel av dem är behäftade med fel. Då det är en mängd sammanverkande faktorer som kan bidra till skador eller plantors död kan det vara svårt att fastställa om orsaken till skadan/plantdöden var att hänföra till plantorna eller faktorer i uppväxtmiljön. Svårigheter att fastställa orsaken kommer därför bidra till svårigheter för skogsägarna i samband med reklamation.

To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.

This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.

The Secret Fashion Council blends spirituality with fashion, art and design. This jewellery collection shows the connections between parapsychology and quantum physics, based on the study of matter and energy, that everything in the universe is built of vibrations. Many believe psychics have the ability to sense this. By using the skills of a psychic, the Secret Fashion Council invites the wearer to have the jewellery ?read? and evaluated in a most special way, tracing the wearer?s spiritual past, present and future.

Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.

The demand for renewable energy is increasing in Sweden. This consequently increases the pressure for and willingness to pay for forest fuels. One method to extract forest fuel from suitable commercial thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e.

The price of Swedish forest properties has gone up by 77 percent during the past five years. Amongst private forest managers the high price level signals optimism and confidence for the future. Many forest owners manage large capital in the forest and a planned economy is to a larger extent demanded to achieve a positive economic result. Forest is long-term and to maximize a single year without planning for the years to come results in less optimization of the parameters available to achieve a favourable economic result. This case study investigates the investment of two forest properties situated in Götaland. The management of the forest has been planned for both properties during a period of ten years.

Africa is one of the regions most affected by climate change. However its forests are important carbon sinks for the whole world, and if recognised as a global public good, could be conserved and contribute to green house gas emission reductions. A global mechanism, Reduced Emissions from Deforestation and forest Degradation(REDD+) aims to help developing countries in reducing emissions from deforestation and forest degradation, and enhancement of carbon stocks. REDD+ strategies may, however exclude local forest dependent communities from forests in order to conserve and maximise carbon stocks, thus having a severe impact on local livelihoods. Therefore, how local communities can participate and share benefits from REDD+ is a key concern.This study investigates how three forest dependent communities in the Nazinon forest, in Southwest Burkina Faso could financially benefit from a REDD+ project.

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.

Telemedicine is the use of information and communication technology to provide clinical health care at a distance. This approach is usually adopted to bridge the distance in rural settings, but it is also a method to meet demographical and economical challenges. Västerbotten, a sparsely populated county with an ageing population, is in leading edge when it comes to telemedicine. The purpose of this report was to examine the diffusion and the inventory of telemedicine in the county council of Västerbotten from a geographical perspective. To gain a deeper understanding of diffusion and inventory of telemedicine, my purpose was also to examine these processes from an international and national perspective.

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%.

This study was an assignment for the company Holmen which is located in the region of Örnsköldsvik, Sweden. The study was focusing on the responsibilities of a forestry planner during the planning season. The study was investigating about how much time the planner spent in the office, in the car and out in the forest. Any other issues that would cause delays were also identified. To be more effective and to increase the number of objects to a district bank, a better preparation in the planning stage (for thinning?s or clear cuts) is needed as well as faster transition on to the next area.

The aim with this independent degree project of master thesis is to find what the user opinions of the intranet in a county council is. The paper seeks how the question about how the culture in the organisation was affected by the use of the intranet. An important part is to explore the expectations and acceptance of the intranet and get a picture of which functions and services support day-to-day work with good quality. One goal is to find out how the intranet users feel that the communication, information and usability can be developed.The focus group interview is a qualitative method that has been applied for gathering data from the respondents, who participate in the investigation from the county council. The used method is unstructured focus groups containing the three dominating categories of staff in the county council.

Det finns idag ett stort behov av att kunna klassificera stora mängder data på ett effektivt sätt. Prediktiv modellering är ett område inom data mining där prediktioner kan utföras baserat på tidigare erfarenheter. Dessa prediktioner presenteras sedan i en modell. Avvägningen mellan tolkningsbarhet och träffsäkerhet är ett begrepp som beskriver hur träffsäkra modeller ofta är ogenomskinliga, medan genomskinliga modeller ofta har lägre träffsäkerhet. Detta är ett problem eftersom det finns ett behov av modeller som är både träffsäkra och tolkningsbara.I denna studie visas hur man kan gå till väga för att skapa en modell som har en träffsäkerhet i klass med en ogenomskinlig modell, men samtidigt har en högre tolkningsbarhet.
