The forest in the county of Småland has been utilised for a long time. One of the most important forms of utilisation of wood has been charcoaling for the benefit of the iron industry. Shortage of forest in relation to the iron industry, was discussed already in the 17th century in Sweden. The aim of this study was to analyse the purchase and consumption of charcoal at Storebro Bruk, an ironwork in Småland, during the period 1793-1850, as well as analyse the shortage of forest at the time. To determine the utilisation of the forest in the area, I have used historical sources from Storebro Bruksarkiv.

Is there such a thing as unadulterated nature? All that surrounds us is culturally modified by man somewhere along our past. But culture is only a fictitious conception itself, created in an attempt to break the world into controllable objects.So in what do we find culture? In everything? In the objects or the stories they embrace? Who chooses what?s worth saving and how to save? Choosing what is culture is made from personal, ingrained dichotomies of what?s important and what is not. A selective eye creates a distorted truth, which could have unintentional long-term effects.This thesis will give a historical account of the archaeological discipline?s development in tending to our cultural heritage.

Herbivore impact on the Swedish forest has under a long time been a common subject of debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the Trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the water was also studied in relation to shade, meandering and water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the water was shaded, no vegetation overgrowth could be found. Therefor Trees should be planted to prevent any future overgrowths.

Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted Trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.

A few hundred metres from the beach on Fårö, Gotland, is a small lot with pine Trees, green moss and wild fl owers situated, owned by my brother and sister. Eventually they would like tobuild a summerhouse here, in close proximity to their relatives. My project is a proposal for the summerhouse at the site, within the restrictions of 61 m² building area, with focus on interior,exterior and the environment.My proposal is a house close to the surrounding nature, with reference to the the building tratition on the island and with local materials. Orientation to the sun, road and neighbours hasall infl uenced my ideas of this house and the relation between inside and outdoor living, were important in my creative work. The aim was to create a house made for the family and theirholiday lifestyle and allowed consideration for the possibility of a growing family with more children.

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

Allanblackia is a genus of Trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the Trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

The Swedish Forestry Research Institute implemented an experiment which began in the year 1979 in a by moose browse damaged area in Sweden. An audit in 2014 of the moose browsing study called ?Furudalsförsöket? is the underlay to the study's results. By comparing Scots pine stands development in relation to known damage obtained thereby gives the understanding of how browsing affects the short and long terms impacts of Scots pines quality and volume production. The results of this year's audit reveal that the standing volumes in the undamaged and damaged areas represent a significant difference. The number and volume of the ingrown Trees constitute a larger proportion of the areas that have been heavily browsed. It also proves once again that that all damage classes had a downward trend, which means that the damage is concealed with time.

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the Trees on basis of the number of annual rings at stump.

A new Swedish political approach to forestry was initiated 1993, that put goals of production and environmental issues into equal importance to Swedish Forestry Law. Earlier nature conservation very often declaimed preservation the best way to conserve nature, but recently it is clear that many highly biological values are due to former land use or disturbance. Many old pastures or cultivations dominated by deciduous Trees are today characterized by a dense overgrowth of Norway spruce. By actively paying attention to nature in forestry (nature restoration), it is possible to partly reconstruct habitats or disturbances that are necessary to favour the biological values. The aim with this master thesis is to study the nature restoration, (NS, Swedish abbreviation), performed in 11 forest sites in the middle of Sweden 8-14 years ago. Since NS recently have become applied, it has never yet been evaluated.

A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning. In this study the distribution of the biomass within lodgepole pine Trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.

The aim of the study was to compare how the population of pine (Pinus sylvestris) and spruce (Picea abies) have changed between 1927 and 2013 in the oak landscape south of Linköping. A field study was carried out in 22 two kilometre lines which also had been studied in 1927. In these lines, which where ten meters broad and had a direction from west to east, the pines and spruces were counted, measured and classified by steam diameter. The obtained result was that the basal steam area (m²/ha) had increased for pine (44%) and spruce (57%) between 1927 and 2013. The amount of Trees had increased in all diameter classes except thinner pine and spruce with a diameter of 5-10cm.
