Möjligheternas skog : utveckling av Teleborgsskogen som tätortsnära rekreationsskog i samarbete med närboende och aktörer
The Swedish forestry aims primarily maximize production and economical wins. However, especially urban forests have great qualities as space for recreation and children?s play, which means that other goals should lead the forests management. The Teleborg forest is a wooded area in Växjö, surrounded by urban dwellings, schools, nurseries etc. A great part of the forest was wind felled during the storm Gudrun in 2005 which changed the forest, earlier dominated by spruce, dramatically.
Svensk plantskoleproduktion 2003 :
This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm.
Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).
Utveckling av en äldre villaträdgård : från oplanerad till planerad
The result of this work is a plan for the development of an 1128 m2 elderly raised garden. The purpose has been to create an overall plan covering the long-term development
of the garden.
The work process has covered a description of the garden of today, review of requirements, analysis of the garden sections, design of a new plan as well as starting the construction of the new garden.
The plan covers a time period of a couple of years to create the new garden since the
construction work is carried out during spare time with small resources available. The planning must contain review of functions such as protection from insight, eating area and compost area.
Also the esthetic expression must be planned. Colors, shapes, choice of material and plants together make up the esthetic expression.
It is recommended to include anything you wish to create in the garden. In a raised garden one has to overcome the step to remove trees and shrubs and think different.
Perenner i offentlig miljö : en samling exempel och erfarenheter
Abstract:Perennials in public areas have during the latest decades been more and more popular. This group of plants has become a more accepted komponent when creating pleasant public places, and people begin to see the functional aspects. Perennials do also give a colour- and senceexperience in a more detailed way than can be achieved with only trees and shrubs. One of the ojects of this essay is to give more examples of motives for using perennials in urban areas.Having in mind the increasing use of perennials, you can expect a growing need for better understading of how to create successfull perennial plantings. In spite of the increasing interest it is hard to find any written information in this subject.
Export of wood pellets from British Columbia : a study about the production environment and international competitiveness of wood pellets from British Columbia
The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it.
This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.
Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry
Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land
management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC)
compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on
crops during drought.
The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to
study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.
Vattensork och åkersork - skadegörare i svensk fruktodling
There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.
Identifiering av gallringsbehov med hjälp av flygburen laserskanning :
Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.
The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores
To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.
En ?terinventering och analys av den svenska populationen av svart nervmossa (Campylopus atrovirens)
Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.
Hur kopplad är asp till tidigare jordbruksmark? : en studie av aspförekomst och tidigare markanvändning i fem län i Mellansverige
Aspen (Populus tremula) is a tree that is important for biodiversity. It is a pioneer tree that is favored by much light. It is possible that aspens that regenerated on agricultural land have a different importance for biodiversity than aspens that regenerated in forests, since their conditions have been different. By studying how the land use have changed you can see how many of today?s aspens regeneretad on agricultural land.
Produktivitet och kvalitet vid stickvägs- respektive beståndsgående förstagallring :
Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110).
The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.
Effekt av sederingsrutin och vikt på höftledsröntgen hos hund
The aim of the study was to investigate whether the sedation method had an effect on the screening result for hip dysplasia (HD). Another aspect considered was if the dog?s weight had an impact on the results. This study was a follow up on the results from an earlier study of sedation routines in Swedish dogs. The breeds included in this study were the same as in the earlier one; German shepherd, Bernese mountain dog, Boxer, Newfoundland, Rottweiler, Saint Bernard, Golden and Labrador Retriever.
En upplevelsepark som stimulerar känselsinnet hos synskadade barn ? utformning och materialval
Abstract/////
Parks and green spaces are important to a lot of people today. Are these parks made for us all? Is it possible for a person with a sight disability to explore and take part in all the things these places have to offer? They can probably take in some, but I think there are more effective ways of planning for the blind and sight disabled allowing them to explore using their tactile senses.
The environment is vital for children?s development.
Slottsholmen på Svaneholm : en fallstudie om en historisk park- och gårdsmiljö och hur den kan ha tett sig under 16-1700-tal
The park at Svaneholm is a place, the history of which is very little known today and the needfor better knowledge has been the cause of this investigation. The essay is primarily limited tothe time from late 17th century up to the end of the 18th century and takes stand on profoundinvestigations in accessible map-and archive material. The results presented show a manorhill, which during the course of a hundred years was subject to several changes and in bigparts consisted in other than park/garden.Burman related to the manor hill containing a cowshed, a large dam and a parterre garden isix quarters and it is plausible to think, that this establishment generally was built as producedon the plate.In the 18th century the construction is being changed, they go on building at the cowshed andin 1707 there are totally 268 livestock on the farm. In 1723 the garden is represented in amuch bigger scale than on the plate from the 1680:s, but it is not possible to tell, whether it isnew or not.Parts of the parterre garden is remaining during the whole of the 18th century, for the leastuntil it is being squared, but on two of the squares there was built a riding-groundMoreover the cowshed burnt down and was only partially reconstructed.The image given by the archive material is at the same time variegated. The inventory list ongarden tools from 1726 gives an image of gardening more directed to growing and pathshuffling, while the possibilities of keeping the parterres were fewer (e.g.
