Skogstillväxten ca 20 år efter plantering på Flakmossen : dikningens och gödslingens betydelse vid beskogning på en avslutad torvtäkt i Värmland

This study was performed in an afforestation experiment established 1982 on an abandoned peat harvesting area, Flakmossen, in the province of Värmland, SW Sweden. The experimen-tal design include planting with Scots pine (Pinus sylvestris), in combination with various drainage intensities (20, 30, and 40 m between ditches), and fertilizer doses 0, 100, and 200 g PK per seedling applied at the date of planting. The aim of this study was to achieve more knowledge about the conditions on afforestation of peat harvesting areas, especially regarding drainage intensity and fertilization requirements, by means of determining the stand growth and yield in the Flakmossen trial. The forest growth did not differ significantly between the drainage intensities tested when the same amount of phosphor and potassium fertilizer was added. Thus, shorter distances between ditches than 40 m can not be recommended. When no fertilization was carried out seedling survival was very low, and the growth of sur-vived seedlings was poor. The largest diameter and height growth were observed in the areas where the highest dose of phosphorus and potassium (200g/seedling) was given.

Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Stureholm - en herrgårdsträdgårds historia, utveckling och framtida skötselmål :

Stureholm Manor and garden is a relatively young farming unit on clay soil in the north western part of Skåne, a province in Southern Sweden. Since the middle of the 19th century the landscape has been actively cultivated and has been transformed from oak forrest into farmingland of high efficiency. The industrial era during the 19th and 20th centuries meant new posssibilites for cultivation of these clay soils. With equipment like steam ploughs and the possibility to obtain fertilizers, the harvest increased considerably. This increased prosperity provided estate Stureholm with a beatuiful corps de logi, a manor. The trends prevailing in Europe around the turn of the century 1800-1900 against the growing industrialism, was turned into a artisan movement known as Arts and Craft. The Swedish followers idealized our Swedish history and they took the turn of a national romantic movement that later turned into neoclassicism.

Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

Det första uppdraget : om studenten som företagare

This is a 20 points graduation thesis, performed at the Department of Urban and Rural Development at the Swedish University of Agricultural Sciences in Uppsala. The main aim of this thesis is to examine what it is like to combine studying with working and starting your own company. Furthermore, I want to be able to convey this knowledge to others. An important part of being a landscape architect is informing people, and making rather abstract issues tangible. The word 'entrepreneur' is originally French. Today, we think of entrepreneurs, or contractors, as energetic people, who dare to try new ideas. There are many reasons why people start their own company, but the most common ones are the wish to fulfil oneself and to be able to plan one's own time.

Fukthaltsförändringar för skogsbränsle : En jämförelse av torkförloppet i grönrisskotade och brunrisskotade vältor

In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.

Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar

Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. I alsowanted to identify the edge effects and their sources and finally compare the results between thedifferent regions.The data sources used are derived from the ongoining research project Landscape structures, patterns ofbiodiversity and conservation strategies in the Baltic Sea region by Kari Lehtilä, Patrik Dinnétz ochTiina Vinter who have made a record of all herbaceous plant species in four randomly chosen forestregions situated around the Baltic Sea: Estonia, Skåne, Södermanland and Germany. I made statisticalanalyses, using the computer program R, concerning the distribution of species in the edge habitats ofthe forests as well as in the core habitats. I performed generalized linear models and then variationanalyses with the factors light and biomass in order to investigate wether edge effects might appear dueto these factors.

TV4 - kan kommersiellt och demokrati gå hand i hand? : - En studie om extern påverkan i en tv-kanal och hur kommersiella och demokratiska intressen förhåller sig till varandra 

Introduction: As the media landscape has changed so has fierce competition in the market, giving an effect of stronger commercialization of the media. Societal problems in our society are caused by increased commercialization and market orientation. Media has gone from trusted social institutions to focus on their own economic interests, where owners are expected revenue. The content of the media is characterized more and more by entertainment, because it attracts a larger audience. On one side media is expected to contribute to democracy in society and on the other they are expected to contribute profits to their owners, which creates a conflict in today?s media society.

Hur kan mångfalden gynnas på SCA:s naturvårdsareal? : natur- och kulturvärden i Peltovaara mångfaldspark

Områden med skyddad skog i norra Fennoskandia, som tidigare beskrivits som orörd urskog, har på senare tid visat sig vara påverkade av långvarigt mänskligt resursutnyttjande. Historiska analyser av ekosystem, där även antropogena störningar beaktas, har därför börjat lyftas fram som en viktig del i naturvårdsarbete (Foster m.fl. 2003). De hjälper oss att förstå hur strukturer och störningsdynamik har förändrats över tiden, vilket kan vara till stor hjälp vid skötselplanering och restaurering. Det övergripande syftet med den här studien var att kvantifiera kulturspår och analysera förekomsterna av kulturvärden i relation till framförallt naturvärden, men även sociala värden, i ett skyddsvärt borealt barrskogsområde. Min avsikt var att försöka exemplifiera hur skogshistoria kan användas för att skapa underlag för skötselplanering i områden med naturvårdsanpassad skogsskötsel.

Svartedalens naturreservat : en social rikedom värd att utveckla!

Svartedalens nature reserve a social richness worth develop. The nature reserve of Svartedalen is an area of high biological and social values. The reserve is located close to several densely populated areas. The reserve has been classified as a national area of interest for nature conservation and outdoor life, and as a Natura 2000 area according to both the bird- and habitat directions. The reserve is the largest landarea in Västra Götaland, 3 410 hectares, where a resolution has been made about all these forms of protection. The foundation Skogssällskapet owns 1 956 hectares of the reserve, at 1 384 hectares of the property they pursue FSC-certified silver culture, according to current management plan.

Ekjättars framtid : en fallstudie av gammelekar idag och i framtiden vid olika skötsel- och restaureringsscenarier i Hjulstaområdet, Enköpings kommun

This Master's thesis work was done at SLU, Uppsala, Sweden in cooperation with Upplandsstiftelsen and Uppsala County Council. The studied area is pointed out as an area for EU´s LIFE project, NATURA 2000, concerning the Scarabid beetle Osmoderma eremita. The studied area lies in an agricultural landscape rich on deciduous trees, about 15 km south of Enköping in the County of Uppland. The species is dependent on large, old, hollow trees, which are exposed to sunlight, usually oak trees in this area. I studied the area in detail concerning large old trees (>70cm ø), middle-aged oak trees and young oak trees.

Vedlevande lavar på döda grenar på levande träd i produktionsskog

Saproxylic lichens in managed forests have less substrate available than in unmanaged forests due to the shortage of dead wood. However, a suitable substrate for these lichens could be dead branches on living trees. To this date, there has not been any systematically collected data about theabundance of dead branches on living trees and the lichens growing on these branches in managed forests. The aim of this study was to see where dead branches were located on living trees of Pinus sylvestris and Picea abies, how large the surface area of these branches was and what lichens grewof wood on these branches. The study was made in Finspång, Sweden, where 11 forest stands of P.sylvestris and P.

The distribution of Moose (Alces alces) during winter in southern Sweden : a response to food sources?

The traditional Swedish way of dealing with browsing damages made by moose, is to reduce the moose population. However, a growing way of dealing with damages made by several ungulate species, including wild boars in particular is to redistribute them with supplementary food sources. Attracting them to settle in habitats less vulnerable to damages made during foraging. This study we tracked collared moose in southern Sweden from January throughout April in the year of 2009. From the tracking data their ?favourite? positions was selected and visited in order to study the features that attracts moose during winter.

Do grizzly bears use or avoid wellsites in west-central Alberta, Canada?

The purpose of this report is to make an evaluation of the self-monitoring for scarification which Stora Enso is using and this study deals with the effects and importance of scarification. A comparison is made in this study with the purpose to highlight any differences between some of the leading forestry companies and significant forest organizations in Sweden. The companies represented in this report are Korsnäs, Mellanskog, SCA, Sveaskog and Södra. In the beginning of this study an interview form was set up together with Daniel Forsberg at Stora Enso. Stora Enso is the head object of this report and seven interviews were made within that company. At the other companies only three interviews were made within each one, with an exception to Mellanskog who wished four.
