Naturens betydelse för människan är stor och den tätortsnära skogen utgör en viktig plats i den växande urbana befolkningens närhet. Ungefär två kilometer nordost om Falu centrum ligger Lugnets naturreservat, ett tätortsnära område som nyttjas av allt från motionärer och barnfamiljer till elitidrottare. Syftet med den här studien var att genomföra en syntesanalys över hur skötseln av Lugnets naturreservat kan utformas för att tillgodose så många intressen som möjligt. Genom kvalitativa intervjuer med ett urval av områdets intressenter kartlades deras nyttjande och synpunkter. Tillsammans med befintlig teori inom området utformades generella och specifika skogsskötsel- och förvaltningsförslag för reservatet.

Epifytiska lavar utgör en viktig del av floran i den boreala zonen. Några miljövariabler är kända för att styra artrikedomen och artsammansättningen av epifytiska lavar på beståndsnivå, såsom träddiversitet, beståndsålder, fuktighet och trädens barkstruktur. Skogsbränder utgör den viktigaste störningen i boreala skogar men studier på brandeffekter på epifytiska lavar är mycket få. Detta arbete undersökte artrikedomen, diversiteten och artsammansättningen av epifytiska lavar på basala delar av björkar längs en gradient av 30 skogsbeklädda öar som skiljer sig i storlek och brandhistorik i den norra boreala zonen i Sverige. Målet med studien var att undersöka hur lavfloran påverkades av östorleken och miljövariablerna längs gradienten.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

The aim with this study was to investigate mortality in older respectively younger beech stands (Fagus sylvatica), the different types of dead wood in the forest and the availability of coarse woody debris (CWD). The research was carried out in previously managed and seminatural stands in Biskopstorp and Frodeparken, located north of Halinstad in Halland,Sweden. Data were collected from 22 stands with at least 50 % beech and with a minimum age of 5 1 years, ranging in size from 0,67 to 19,9 ha. A transect was placed in each stand, in which the diaineter on both dead and living trees with a minimum diameter of 50 mm was recorded. On seven to 13 dead trees, depending on the size of each stand, decomposition stage, primary and secondary cause of death, amount of fungi and the type of the dead wood was noted.

Detta examensarbete har haft som syfte att undersoka om skogsbruksplanerings­ metoden "Avdelningsfritt skogsbruk" kan tillämpas med tillfredsstallande resultat i sodra Sverige. Studien utfordes pa Asa skogsvårdsgård ägd av skogsvårdsstyrelsen i Kronobergs Ian. Fastigheten ar belagen strax soder om Asa ca 30 km norr om Växjö. En pilotstudie har tidigare utforts i Vilhelmina (Holmgren & Thuresson 1995, 1996). Vid skogsbruksplanering ar det viktigt att habra data om skogen att basera beslut pa.

Under de senaste 20 åren har priset på skogsfastigheter ökat dramatiskt. Historiskt sett har priset på skogsfastigheter haft en tydlig koppling till skogens avkastning, men detta samband tycks inte längre gälla. Utöver värdet av skogens ekonomiska avkastning, tillkommer idag värdet av ickemonetära resurser som tidigare hade en begränsad betydelse för fastigheternas pris. Faktorer som bonitet och åldersfördelning påverkar en skogsfastighets avkastning. Men är det självklart att dessa faktorer även påverkar skogsfastigheters pris? Om utvecklingen av fastighetspriset medfört en försvagad koppling mellan avkastning och pris, kan detta då förklaras av att tidigare prispåverkande faktorer inte längre beaktas i fastighetsvärderingarna? Syftet med studien var med bakgrund av detta att undersöka hur ett antal faktorer påverkar fastigheters pris; däribland åldersfördelningen och boniteten.

Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

This Master Thesis is a product development project that has been carried out in cooperation withLappset Sweden AB.The purpose has been to develop a group of products suited for parks andtraditional playground locations. The specific target area has been courtyards of newly builtresidential areas. (These pieces of open land resemble glades that can be found in the forest,which in Swedish is called ?gläntan? and has given name to the product family). Therefore thedesign should match contemporary architecture.

The third most common conifer in Sweden is Pinus contorta (lodgepole pine). It originates from the western part of North America and was brought here in the end of the 1920s. The lodgepole pine is today allowed for commercial plantations in central and northern Sweden, excluding high altitude locations. Since 1979 only plantations with scientific purpose are allowed in south-central and south Sweden. This document is focused on how lodgepole pine manage perform compared with Pinus sylvestris (Scots pine) in the southernmost part of Sweden, Götaland. The idea came from the fact that the Swedish government is evaluating a notification from the National Forest Agency that suggests lodgepole pine to be allowed for commercial plantation even in southern Sweden.

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

Varje år ökar antalet äldre personer och i samband med den ökningen blir även antalet äldre personer med körkort allt fler. Med åldern är det vanligt att reaktionsförmåga, syn och hörsel försämras vilka alla är viktiga egenskaper för trafiksäkerheten. Läkare i Sverige är skyldiga att rapportera till Transportstyrelsen om en individ inte anses vara lämplig att köra bil. Att läkare över huvud taget tar upp körkortsfrågan med sina patienter sker endast i 60 procent av fallen och därmed fortsätter många olämpliga körkortsinnehavare att köra bil. Majoriteten av länder inom Europeiska Unionen (EU) har någon form av övre åldersbegränsning i körkorten där körkortsinnehavarna måste genomgå en kontroll för att få körkortet förnyat.

Stage Design is design for action and contains décor, side-scenes and properties, as well as costume and grease-paint. The one responsible for this is the Stage Designer, who together with the Director, creates the best conditions for the actors to perform in. The stage, where the play takes place, could be either in a theater, an auditorium, or in another sort of room, at another place, inside or outside, and where the place itself inspires to theatrical performance and expressions. This type of theater is called Site-specific theatre. Two examples of this is the workshop ?Skogen sjunger? (eng.

This master thesis is made in co-operation with the Department of Forest Management and Products at the Swedish University of Agriculture in Uppsala and the Forestry Association in Stockholm. The purpose of the Master thesis was to describe how pre-schools in Sweden use forests and green areas, and to understand how different factors can affect the use of the nature. The purpose of the interviews was to create a picture of attitudes and routines of the pre-schools, in the matter of visiting the nature. The thesis is built on interviews where fifteen pre-schools in five large cities around Sweden participated. Among these pre-schools, five of them worked with special focus on nature, while the other ten did not have any particular focus connected to their activity.
