GIS-modellering av habitat för vitryggig hackspett (Dendrocopos leucotos) som hjälpmedel i naturvårdsplanering på landskapsnivå :

The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.

Strategisk utveckling: En studie av strategi hos internetbaserade företag

Strategic development is something that concerns all companies, regardless of which industry they?re in. There is extensive research on this topic but one can question if the same theory also applies to E-businesses. Using case studies, this paper looks at strategic development in E-businesses and tries to answer whether strategic development in internet based companies is unique or if existing theory can still be applied. The predominant approach is to look into if E-businesses, due to a turbulent environment, rely less on market research and focus more on internal resources than would be expected by companies in more stable environments.

Utveckling i Latinamerika, En teoriprövande studie med fokus på Costa Rica och Nicaragua

This essay deals with development in Latin America. We have picked out some factors that the theories in development theory emphasize on. The first section of the study consists of a statistical analysis, were the main purposes are to study the relationship between the independent variables and the dependent and to choose which two countries we should focus on in the next section. The countries we decided to study were Costa Rica and Nicaragua, because these countries have shown very different levels of development. From this study we have concluded that political stability, economical investements and human investments are the most important factors when creating development..

Säkerhetstänkande integrerat i systemdesign via formaliserade metoder

Systems development methods mirror different organizational perspectives, and not all methods are formalised, but what they have in common is the purpose of structuring and supporting systems development processes. Which method would be the most suitable may be determined by the systems development context at hand, because every systems development context is unique. Information is a valuable asset in today?s organizations, and it needs to be protected against both internal and external security threats. In our essay we aspired to find and present suggestions as to how systems developers can include security in the very design based on formalised systems development methods to create systems that are better prepared to meet the security challenges of today.

Motorsågskörkortet - en utvärdering av Skogsstyrelsens motorsågsutbildning vid Frossarbo kursgård 2005 - 2007 :

The use of chainsaws in both private forestry and commercial companies is highly associated with personal injuries and accidents with deadly outcome. As a result to this, a driver?s license for chainsaws was presented in the year 2005. To get the license you have to attend a course given by the Swedish Forest Agency or one of several private educators. This study is an evaluation of one course given by the Swedish Forest Agency in Uppsala.

Time efficiency in a product development process

Purpose: We wish to gain a deep knowledge about product development processes in relation to the aspect of time in companies in highly technological and rapidly changing markets. The purpose is to establish how organizations better can employ time as a resource to make the product development process more efficient. Conclusions: Information we gathered from theory and primary data show that information flow, synchronization and time profit when seeing time in three dimensions are factors which should be reflected in the architecture of a product development process. To illustrate our findings, we decided to create a model..

Förröjning i förstagalling - vad kostar det och följer utförarna instruktionerna?

This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :

According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.

Traktstorlek före och efter omarrondering i Dalarnas län -frågor kring Lantmäteriets båtnadsberäkning

Land consolidation is a major problem in many countries in Europe. In Sweden, mainly the state of Dalarna, there is a strong consolidation of forestland, probably the strongest in all of Europe. The consolidation is a big obstacle for forest management and ownership questions due to the often long and narrow strips of land. One of the main reasons for land consolidation in Dalarna results from the heritage procedure, were land is divided between all of the inheritors. To improve the consolidation large surveys in the consolidated villages in Dalarna are carried out. Many laws have to be followed due to the survey.

Metodutveckling för planering och genomförande av dikesrensning med moderna metoder

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

Att prognostisera avverkningspotentialen i privatskogsbruket

For the actors in the Swedish forest industry, it is important to have the ability to forecast the state in the privateforests. The information that comes out of the forecasts will be the base for the activities strategic direction.The aim in this exam is to survey what information that is present today as basis for forecast calculation, andeven to examine what other possibilities it might have in the future.From a limited geography and out of different time perspective forecast the felling potential in the privateforestry.With the word felling potential means regeneration felling and thinning. The exam will answer the questions:What information is needed to build a relevant forecast model?Is this information available today?Is there information to buy that would improve the forecast model?The result of this exam will be presented in form of a ”case study” showing the opportunities in the market tocreate a forecast calculation of felling potential in the private forestry within the Forest Owners’ AssociationMellanskogs wood-area Dalarna..

Effekt av karbonatisering med biogas på aska från trädbränslen

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.
