Liv i d?d ved: En unders?kning av f?rh?llningss?tt till d?d ved p? ?ppeltr?d i tr?dg?rdshandb?cker och bland yrkesverksamma tr?dbesk?rare
In this essay, several factors in apple tree care (specifically in relation to whether dead wood
should be kept or removed) are highlighted for example, aesthetics and biodiversity.
To present some background, the essay begins by introducing some previous literature on
dead wood. This leads into how dead wood is treated within forestry. Next, previous research
on dead wood in fruit trees is mentioned. Cultural and historical management methods are
also highlighted.
Do retention trees affect the composition of ectomycorrhizal fungi? : a comparison between clear-cuts areas with and without retention trees in pine forests
Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.
Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län
The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.
Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark
In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.
Att upprätta ett konsignationslager ? en best practice
I en mer global och konkurrensutsatt marknad krävs, i allt större utsträckning, att företag väljer att differentiera sig med specifika kundlösningar istället för den enskilda produkten. Genom att, tillsammans med kunden, skapa värde knyter man denna närmare till sig.
Ett konsignationslager är en strategisk lagerlösning för att minska avstånden mellan kund och leverantör samt att minska kedjans totala lagerkostnad.
SCA Timber har begränsad erfarenhet kring konsignationslager. Av den anledningen har det funnits oklarheter kring hur arbetet bör organiseras.
Syftet med studien är att ta fram en best practice för hur SCA Timber ska arbeta med upprättandet av framtida konsignationslager.
Studien är en multipel fallstudie av fyra verksamheter inom SCA och baseras på kvalitativa, semistrukturerade intervjuer med respondenter som varit inblandade i upprättandet av konsignationslager. Det empiriska materialet består av fjorton intervjuer. Studien utgår ifrån ett teoretiskt ramverk bestående av teorier kring projekt, kritiska framgångsfaktorer i projekt och skapandet av nyttjandevärde.
Locally valued habitats, species and sites and their significance for collaborative land use planning around Manusela National Park, Central Seram Island, Moluccas, Indonesia
When new land use policies are made, opinions of stakeholders need to be taken in account, to avoid future conflicts. The motivations of commercial enterprises are often clear and easily communicated but due to inaccessibility and language barriers the indigenous people?s perspectives and needs are harder to reveal. This study therefore aims to identify species and sites of importance for the local people in Masihulan village on Seram Island, East Indonesia. This is a first step to facilitate better integration of local people´s needs into local government decision-making processes.Researchers at the Center of International Forestry Research (CIFOR), with headquarter in Indonesia, have developed an approached called ?Multidisciplinary Landscape Assessment? that aims to assess important natural resources for local communities in tropical countries.
Ny huvöppningslösning för Eco-Logs skördare : Från idé till tillverkningsunderlag
This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.
Trust within small-scale forest management - a local case study in Southern Sweden
In the forest sector, non-industrial private forest (NIPF) owners commonly interact with numerous stakeholders (e.g. forest managers, timber buyers, harvesting contractors and advisors) for counseling, planning, selling and hiring. Forest management is therefore built and influenced by the
relationships between NIPF owners and other stakeholders. In the local context of a Southern Sweden, the Swedish Forest Agency (SFA) and the Southern Forest Owners Association (SÖDRA) are very influential stakeholders in small-scale forest management. Based on qualitative interviews and by means of grounded theory, an analysis of the relationships between NIPF owners and the mentioned organizations was carried out in order to understand the social context at the genesis of forest management decisions.
Nästa generations syn på skogsägandet och skogsägarrörelsen : en enkätundersökning bland vuxna barn till dagens medlemmar i Norra Skogsägarna
The future of the forest owners? associations are intimately coupled to the development in family forestry. Forecasts have been made that predicts that the number of forest properties for sale on the open market will increase as the interest among the children of the property owners is considered to decrease. The associations are also affected by continuing individualism in the society which may affect attitudes to as well as interest in membership.
The objective of this study was to study the attitudes among grown-up children of members in a forest owners association towards overtaking the forest property as well as membership in a forest owners association.
LUFT : barnperspektiv på utvecklingsarbetet BUSS
In 2002 the Norrköping municipality decided to establish a number of supportive teams and one teaching group with the purpose of developing alternative supporting efforts for children with social problems. This development work came to be called BUSS. BUSS today consists of four local teams, team Ett, team Norra, team Torpet and the Mathson School.The teams? focus, beyond the commission from Norrköping municipality, is to reduce the number of children being placed outside their own homes, get them to function in school, develop their self-confidence and social competence. Also their task is to support parents and take up a functional spare time for the children.
Effekter av "Billigaste väg" för Stora Enso Skogs transportverksamhet :
Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.
Utvärdering av produktionsledarens användning av Holmen Skogs datorbaserade stödsystem vid operativ planering av avverkning
The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems.
The aim of this study is to:
? investigate the work pattern of the production managers when using the information system to plan the harvesting operation;
? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system;
? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern;
? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion.
The conclusions of the study were:
? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning;
? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information;
? the computer systems are however divided in many subsystems.
Kvalitetssäkring av markberednings- och planteringsuppföljning hos SCA Skog AB Jämtlands skogsförvaltning :
Quality assurance means to systematically work for better understanding of the customers needs, demands and expectations. The goal for this study was to investigate how quality can be assured in the job follow up that is made by forestry contractors after soil scarification and planting. The study consisted of a description over the current follow up process at SCA forest AB Jämtlands forest administration, analysis of current follow up situation and an investigation of follow up process made by contractors in other line of business.
The first step was a statistical comparison where the own follow up made by contractors were compared with follow up made by SCA them selves over 100 stands. Two soil scarification contractors and two planting contractors carried out the silvicultural measures. The results showed that significant differences between a number of quality factors measured, for example number of approved plants or approved scarification points, average score on stand and number of totally planted plants.
Lean och värdeskapadnde sjukvården : En fallstudie
Now a day?s there is dramatic change from traditional to digital information processing in construction industry. This change can be visualized in the project concept stage where it now has accessibility to join all the data in one place. Location-based planning technique simplifies scheduling by visualizing the schedule efficiently and has many advantages such as might shortened the project period by about 10 - 20 % if the company uses location-based technology, reducing risks in many ways by maintaining production continuity and identify collisions between things etc. Vico Office software has been used for Location based planning technique and in this thesis.The purpose of this thesis work was to demonstrate how location -based planning technology change the scheduling stage in Peab, potentially reducing the project time.
Utveckling av ett skogsbolags kontaktstrategi : en kvalitativ intervjustudie bland större privata virkesleverantörer
The supply of raw materials has always been an important issue in the Swedish Forest industry. Buying timber from local suppliers is important. To ensure raw materials to their industries the forest company must offer good prices and good business deals to their suppliers.
The aims with this work are to find out how the contact between private suppliers of raw materials and how the forest company can be developed.
To be able to do a complete study of the problems connecting with this subject a quality interview study has been done.
