Lövängen i nordöstra Skåne :

The purpose of this paper is to study how the wooded hay meadow of the forest district of northeastern Scania is preserved today, and what local history it has, to thereby achieve a better understanding of the dynamics of the landscape and the complex of problems involved in keeping a historical element of the cultural landscape alive. To accomplish this, literature concerning the subject has been studied, experts have been consulted and an example, the old farm Sporrakulla in Östra Göinge municipality, has been studied. The paper states that the wooded hay meadow constitutes an important part of the history of northeastern Scania, where it provided leaf fodder and hay for the farmers keeping cattle. Today, however, only a few wooded hay meadows remain. One of these is the studied example at Sporrakulla, where juridical protection like Natura 2000 and financial support of maintenance like miljöersättningar make sure that the wooded hay meadow will remain.

Lodgepole pine - stability after thinning

SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies.During the years 1996-2005 first commercial thinning of lodgepole pine at SCA took place.The goal of the hereby presented study was to investigate the growth and stability in thosefirstly-thinned lodgepole pine stands a few years after thinning. Furthermore, the objectivewas to investigate the relationship between stand stability and different stand parameters.Additionally, lodgepole pine stem quality was estimated.The study is mainly based on the data collected during an inventory project carried out atSCA in 2008. Altogether 91 lodgepole pine stands in northern Sweden were measured afterthe first thinning.

Tillväxt och potentiell sågtimmerkvalitet i gallringsmogna jämförelseplanteringar med Pinus contorta och P. sylvestris :

The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.

Påverkan av tillskott av död ved och reducerat evertebratnedfall på öringens (Salmo trutta L.) diet i en skogsbäck

Det svenska skogsbruket har lett till minskade vedmängder i skogsbäckarna. Detta kan undvikas genom att orörda kantzoner lämnas. Kantzonsvegetatioen har även visats påverka nedfallet av terrestra evertebrater, vilket visats minska andelen terrestra evertebrater i laxfiskars diet. Ofta lämnas dock inga kantzoner. Vedmängden kan återställas genom ett vedtillskott.

OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.

Gallringsinventering från helikopter utrustad med profilerande laser och kamera för låghöjdsfotografering

Today Holmen Skog finds and selects suitable thinning stands using data on upper height and basal area. These figures are often based on basic forest data that has been updated with the help of growth prediction models. The problem is that these figures are not always correct. The aim of this study was to investigate if a combination of data from a profiling laser and a digital camera for low elevation photography, can be used for collecting data on number of stems per ha, tree species mixture as well as basal area weighted mean height and upper height for stands. The possibility to use these data to assess the need for thinning cutting was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters.

Bergsbrunna södra : analys och programförslag

This final project includes an analysis and a programme proposal for the area Bergsbrunna södra. The area is situated along the railway between Uppsala ? Stockholm, just south of Uppsala city. A new railway station is planned here, which make the area attractive as residential area. There are several values to take into consideration when developing an area. An extensive analysis and valuation may define and protect different characters and values, and also find the places most suitable to build upon. The area consists of three separate characters of landscape: the wide open cultivated fields, the hilly wooden ground and the more varying little valley. There are visual, cultural, social and ecological values to preserve. The south part of the area is woods with high natural values that borders to a national park in the natural forest of Lunsen.

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.

Hur motiverar man beställare till att ge utrymme för landskapsarkitekten att arbeta med brukare i en planerings- och projekteringsprocess?

Residential estates are created without any adaptation to the users who will use them. Clients wouldprofit on involving users in an early project stage to create housing estates adapted to the user?s needsand wishes. Clients of the housing estates that require missions from consultants should realize that noone exclusive can represent other people's needs, regardless of the theoretical expertise they possess. TheSwedish million programme in the 1970s is an example of how objective expertise gained control, whichled to the creation of outdoor environments where few wanted to stay and live.

Förekomst & kostnad av kapsprickor i stormaskadad skog

The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks. For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were: ? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks. ? The averaged sized tree will make it possible to harvest saw timber. ? The trunks can?t be root cut. A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field. Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.

This investigation?s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den?s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders.

Involvera flera : brukarmedverkan i parkplanering

The Civil Engineering office in Skellefteå needs to develop the users' participation in the planning of parks and playgrounds. In order to get such a procedure to work one have to find a method that can work in the daily activity. My work aims to find such a method and to implement it in practice. Apart from helping the Parks departement to find an functional method I will also develop a deepened knowledge about users?participation wich can be very useful i my future profession. This work can be divided in three stages.

Hållbar och framgångsrik? : samband mellan hållbarhetsprestanda och finansiella aspekter i börsföretag

Many companies have historically forced their interests through without any thoughts about the future needs of the humans and the society. In the last few years voices have been raised for a change, companies need to take their responsibility regarding sustainable development.The purpose of the report is to describe and explain possible relations between sustainabil-ity performance of companies and profitability, valuation, industry and size respectively.To be able to judge the sustainability performance of the companies Folksam (2006a) have been used. This is a solid investigation of the companies listed on the A- and O-lists of the Stockholm Stock Exchange by the end of 2005. The sustainability marks have been com-pared with the chosen key values for each hypothesis respectively. With this quantitative data as foundation, a quantitative approach and a deductive method have been used.In the first area of the investigation, profitability, the authors found correlation for the main hypothesis between sustainability performance and ?Return on Total Assets? through a statistical test.
