Skogsbrukets erfarenheter av Poppel Populus sp. i Skåne :

In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species. The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.

Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall

Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.

Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :

Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.

Från gles skog och brokiga ungskogar till homogen produktionsskog : en skogshistorisk studie av Hällforsmarken under 1900-talet

The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.

Barns beteenden i naturen

AbstractThis study is based on qualitative interviews with five-year-old children from a nursery school and two teachers with great experience. The purpose with the interviews is to find out what knowledge these children have about the Right of Common and what the teachers think they need to find this knowledge.The children didn't know what the word Right of Common Stands for but when they got more concrete alternatives they had good experiences. The two teachers had different opinions about what is the most important concerning the stays in the nature. Exercise meant a lot for one teacher. To have fun and to use all your senses were more important for the other one.

Planteringsförbandets betydelse för kvalitetsegenskaper i Contortatall (Pinus contorta var. latifolia)

In Sweden, large scale planting of Lodgepole pine (Pinus contorta var. latifolia) started in the beginning of the 1970?s. At first, the aim was production of pulpwood, but later, also production of timber became considered realistic. Today, Sweden has more than 520 000 ha of Lodgepole pine.

Vilken är den teoretiskt optimala toppdiametern på bokmassaved vid motormanuell avverkning?

The bioenergy market has been introduced relatively late in a perspective of the Swedish forestry. Nowadays branches and tops are used more frequently as bioenergy after harvesting. Therefore, it has developed a competitive situation between pulpwood and bioenergy. This situation has even established some questions. Two examples of these are: ? At what top diameter should the final piece of pulpwood be crosscut to get the best economically result? ? Should the top diameter, at the final piece of pulpwood, be crosscut at a thicker or smaller diameter than what is done today? The purpose of this report is to answer these two questions when the harvesting is made motor manually in beech Stands.

Analys av data från flyglaserscanning :

In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality. StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.

Environmental variables determining the occurrence of the red-listed Carbonicola anthracophila and C. myrmecina in boreal forests

The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.

Glupförekomster i Uppsalaområdet

One special feature in the Swedish nature, mainly in the county of Uppland is one distinctive kind of dip, which can be distinguished from its fast and unaccounted drainage. These dips are called ?glupar? and can mainly be found in coarse-grained pebbled moraine under the highest shoreline (HK). During spring, and particularly when snowmelting occur, the wateramliptude fluctuates a lot until late summer or the beginning of fall comes; these dips are then often almost fully drained. During winter however, the waterlevel Stands high.

Lämplig röjningstidpunkt utifrån björkstubbskottens konkurrens

The purpose of this report was to investigate if there are any correlation between spruce medium height in young spruce Stands and the number of birch stump shoots. The purpose was also to investigate if there are any correlation between the spruce height growth after clearing and the mean height of birch stump shoots. The reason for this investigation is that the problem with birch stump shoots after clearing can be expensive if there must be additional clearings before the first thinning. The study provides no apparent association and therefore no special clearance height is recommended. In the final stages of the work there are given some comments on the study´s weaknesses. Finally topics for further research are suggested..

Grafisk skärpa : ett arbete om gaturummet

The streetscape is a complex environment with a lot of different parts and users. If you look at the streetscapes main parts you have floor, walls, roof and furniture. The floor in the streetscape, the street, consists of the ground and the paving. It can be made of a lot of different materials with both architectonic and practical functions. The walls usually consist of the houses. They have a big influence on the streetscape depending on architecture, heights and widths.

Oreglerad=Fri? En studie om Läkarkliniken

The discrepancy in the rights for healthcare between undocumented migrants and the citizen in Sweden is a prerequisite for the existence of Läkarkliniken. Because of the chosen patient group the clinic Stands outside the regulations from the National Board of Health and Welfare. The aim of this study was, from an institutional perspective, to investigate how such a unique player is designed and where the influences to the design origin from. The task was conducted thorough a qualitative case study with base in depth interviews. High levels of isomorphism were observed between Läkarkliniken and the general healthcare, however differences were seen as well.
