Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå

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.

Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier

This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.

Skolskogen som ekosystemtjänst : En fallstudie om det sociala värdet hos skolskogen

The concept of school forest was drafted in 1970 by the Forest in School organization and is defined as an area occupied by a school for outdoor educational activity. The main purpose of this study was to examine how schools use the school forest in practice, how it can be linked to the forest as an ecosystem service and find out how the forest is taken into consideration in the spatial planning. The study is mainly qualitative in nature and has been based on interviews conducted with educators engaged in outdoor education at four selected schools in a municipality in Sweden. Focus has been on the cultural ecosystem services for school forest, for example the physical characteristics that are considered as positive, forest influence on students' physical / mental health and the educational benefits available to be in the woods. Search has also been made to see how the forest is taken into consideration in the spatial planning and also what a contract agreements involves.

Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

Faktorer som påverkar lönsamheten vid köp av skogsfastigheter i Norrbotten

During the past 20 years, the price of forest estates in Sweden has raised more than the price of timber. The purpose of this study is to investigate if it, despite this development, is possible to buy a forest estate based on economic grounds. Different forest parameters will also be studied to analyse their effect on the profitability. The study is done in cooperation with the company LRF Konsult. Purchase price of 34 forest estates near the coast of Norrbotten, Sweden, has been compared to yield valuation. For the valuation, guidelines from the Swedish author Lantmäteriet was used.

Hotbild för ädellav Megalaria grossa i Uppland och på Gotland :

Megalaria grossa is classified as Near treatened on the Swedish Red List. It is also a so called signals spieces, e. g. a spieces that function as an indicator, signalling a forest that is worthy of protection. The aim of this study was to clarify the status at selected localities in the province of Uppland and Gotland.

Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

Bedömning av skada på naturmiljö och rennäring för den föreslagna fjällvägen mellan Borgafjäll och Saxnäs : - Väg- och transportforskningsinstitutets metod för bedömning av skada på bevarandeintressen

Assessment of impacts on nature and reindeer husbandry by the considered mountain road between Borgafjäll and Saxnäs- Swedish National Road and Transport Research Institutes method for assessment of damage to heritage assetsThere are plans regarding the building of a new road from Borgafjäll/Båtas to Saxnäs, and two road alternatives have been presented. The road has been localized to an area which is protected as a nature reserve and listed as a Nature 2000 area. This report aims to determine the effects on the Nature 2000 area and reindeer husbandry, and to be a source of knowledge for future environmental impact assessment in that project. In order to assess the impact on nature values and reindeer husbandry a method from the Swedish National Road and Transport Research Institute (VTI) has been used. A literature review has been made to prescribe the effects and consequences.

Hur olika skogsägarkategorier har försett sig med underlag för beslut och åtgärder efter stormen Gudrun : en jämförelse av medlemmar och icke-medlemmar, åbor och utbor samt kvinnor och män

During the 8th and 9th of January 2005 a devastating storm named Gudrun entered the south of Sweden and a big part of the forest owners got their forests damaged. The study objective was to investigate on which basis and how the affected forest owners made their managment decisions immediately after the storm and if there are any differences between different categories of forest owners. - Members ? non members in a forest owner association (FOA) - Resident owners ? non resident owners - Female and male forest owner The study is based on a questionnaire survey with the purpose to examine the most important counsellor and information channels of the forest owners. A total of 450 forest owners participated in the survey. Results show that all categories of forest owners prefer professional counselling rather than personal counselling.

Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Trä som fasadmaterial ? behandling och beständighet

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

Identitetsskapande genom meningsfulla upplevelser: Betydelsen av meningsfullhet i musikfestivalsammanhang

I denna uppsats har jag undersökt hur meningsfulla upplevelser i musikfestivalsammanhang kan bidra till individers identitetsskapande.Syftet med studien i denna uppsats är att undersöka begreppen meningsfullhet och identitet applicerat på musikfestival¬sammanhang. Delsyftet är att undersöka om meningsfulla upplevelser i musikfestivalsammanhang kan bidra till individers identitetsskapande. Studien är av kvalitativ karaktär och har ett hermeneutiskt förhållningssätt med en induktiv ansats. Den består av två delar: tre festivalarrangörer på de svenska musikfestivalerna Hultsfredsfredsfestivalen, Arvikafestivalen och Peace & Love-festivalen samt åtta stycken festival¬besökare har intervjuats gällande synen på festivalupplevelser och dess relation till begreppet meningsfullhet. Meningsfulla upplevelser berikar människors tillvaro genom att skapa mening och sammanhang i deras liv och efterfrågan efter upplevelser som förändrar och ger människor något mer bestående än ett minne ökar (Pine & Gilmore, 1999).

Förvaltning och skogsskötsel av ett tätortsnära naturreservat : en fallstudie om Lugnets naturreservat i Falun

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.
