Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project

The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations. The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.

Aslan som en bild av treenigheten Går det att använda lejonet Aslan i Narnia som en bild av treenigheten?

"Children's book is the best style means if you have something to say" is a quote by CSLewis that I focused on in this essay. As a future priest, I am aware of the problems thatexplain some of the Christian church pillars. In this essay I treat the Trinity in relation toteaching children in a future profession. Research in child and adolescent spirituality is onrampage, books with religious messages and ambitions to teach children about Christianethics and morals have been around since Sunday school introduction in Sweden. What arethe tools that can be used to explain even for scholars and theologians difficult concepts? Isit possible to meet kids on their own ground? I see an opportunity for this through theliterature, and the characters they already know outside the ecclesiastical sphere,In this bachelor thesis I have used perhaps one of the major works of children's literatureduring the 1900s, The chronicles of Narnia.

Viltanpassad röjning längs skogsbilvägar som en foderskapande åtgärd för älgen

The moose is a keystone species in the boreal forest ecosystem, but the dense Swedish population do cause some serious problems. From a forestry perspective, their browsing on young Scot pine (Pinus sylvestris) causes extensive losses of revenue. Adjusting the cleaning along roadsides of low trafficked forest roads can favour the production of plant species preferred by the moose. This is thought to redirect the moose´s browsing to the roadsides and thereby decrease the damages on commercial forest.The aim of this study has been to present a first evaluation of the vegetation in roadsides, one year after wildlife-adapted roadside clearing has been undertaken. In the wildlifeadapted clearing operation, the roadside was widened by removal of some trees in the forest edge whereupon a complementary clearing with a conventional chain flail was conducted.

Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys

The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district. The aim of this master thesis was to present an economic analysis of Norway spruce versus birch.

Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :

Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance. As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.

Rumslig fördelning av grov gammal tall i Uppsala stad med tallticka som indikator på höga naturvärden :

Fragmentation and reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning. The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.

Miljonprogrammet : mytbildning, arkitektur och förnyelse

Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .

Att Visualisera Oron : Hotet, subjektet och terrorattentatet i Stockholm 2010

This study examines which socially constructed threats and subjects of security existed during the aftermath of the terrorist attacks in Stockholm 2010. With ideas of identity and difference as a starting point the theoretical framework is then developed with ideas from the new critical security studies including key subjects such as attributes, risk, imaging and visualisation. The study will be executed with the use of a discourse analysis approach using newspaper articles and chronicles as the principal empirical material. The analysis will then follow two separate themes. Firstly, the different threats and subjects of security will be deduced, and also, how these social constructions inevitably create each other and require each other to continue existing.

Markskador vid GROT-uttag : en enkätstudie hos skogstjänstemän

Forestry is increasing on an industrial scale where collection of logging residues takes a greater part. This has resulted in more machinery and heavy machinery driving in the clear felled area, this increases the risk of soil damage that will occur in the form of soil compacting and rutting in the clearings. This affecting on the nature in a negative way and especially in rivers and lakes that are affected by siltation and acidification leading to increased levels of heavy metals and methyl mercury. The purpose of this study was to investigate why there is damage to the ground when working with the slash in forest management from the forest officer point of view. A self-designed questionnaire was used and 45 questionnaires were sent out to various companies all over Sweden.

Erfarenheter av utedrift med köttdjur i Sverige och Kanada :

Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.

Sjunkande pH i Västerbottens humuslager : en kvantitativ analys

Acidification is a central concept in the environmental debate. The effect of acidification of the soil is a matter of a decreasing amount of cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. Acidification has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidification that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.

Mekaniskt snytbaggeskydd

Insecticides will be removed from Swedish forestry, at present insecticides are used to treat our seedlings to avoid them from being attacked by pine weevils. With the forthcoming ban on insecticides alternative protective measures will have to be tested. Holmen Forest Ltd has aimed to find an alternative and have developed a mechanic pine weevils protection accessory as well as a new concept on planting pipes. Studies have been conducted on the behalf of Holmen Forest Ltd to see how planting with the newly developed mechanical protectors and plant pipe stands up against the conventional methods used today. The study was conducted over a three week period. Three factors were compared regarding planting quality including i) pressure around the plant, ii) the depth the plant ended up in, iii) plant angle. Mechanical plant pipes were used in the study, and where tested like a one-handed and a two-handed pipe. The study concludes that further development is needed for the mechanic plant protector to live up to the speed and quality of conventional methods.
