Skogsbruksplanens betydelse för aktiviteten hos privata skogsägare i Älvdalen :
The purpose of Älvdalens besparingsskog is to develop the district and most of all the forestry in Älvdalen. It's owned by about 2 300 private forest owners who's landed properties are located in Älvdalen. Every year the besparingsskogen gives out a lot of its profit in form different types of subsidies for agriculture and forestry. The owners can apply for subsidies for several of the costs that occur in forestry. During the period 2000-2003 the owners are offered forest management plans and pcSKOG-gård at no cost for their private forest properties.
The purpose of this master's thesis was to find out if the activity in the forestry changed when the forest owners got new forest management plans and the computer program pcSKOG-gård.
Mapping of clear-cuts in Swedish forest using satellite images acquired by the radar sensor ALOS PALSAR
This study presents results for observing forest changes in Sweden using multi-temporal L-band satellite data and is a part of the JAXA?s ALOS Kyoto and Carbon Initiative. An extensive dataset of images acquired by the Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR) is investigated for clear-cut detection in boreal forests in northern Sweden (Lat. 64°14? N, Long.
Kombinationsbruk, talltimmer och vilt?
When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.
Skärvstenshögar med människoben i norra Mälarområdet
Mounds of fire-cracked stones is a typical Bronze Age monument for the region around lake Mälaren. They are usually, because of their content, interpreted as piles of rubbish. But as they often have kerbs, are situated on cemeteries and sometimes contain human bones, the traditional interpretation is not fully satisfactory.The main focus of this essay is on the mounds of fire-cracked stones which contain human bones in the region north of lake Mälaren. With a detailed study of these, and a comparison with those without human bones, my aim is to get closer to an explanation why the human bones were deposited. The essay consist of a compilation of 98 excavated mounds and a database with various information gathered from excavation reports and archive documents.With different kinds of osteological aspects taken in consideration, the study shows that human bones have been found in about a third of the mounds.
Fältinstruktion för skogsbruksplanering av inhemska skogar i Andinska Patagonien :
The thesis first objective was to develop field instructions for forest planning of native forests in Andean Patagonia, and the second objective was to test the plan on an actual property in the area. The thesis was limited to studies in the province of Rio Negro. Today, there are no official forest management plans for native forests in the Argentinean province of Rio Negro; thus, there is an obvious need for an official forest management plan with clear guidelines. To be granted permission to manage, i.e. through thinning, the native forests on a property it is required to have a forest management plan that is approved by the Forestry Board in the province in question (Thill, B.
Naturhänsyn på certifierade privata skogsfastigheter : en jämförelse i praktiken mellan FSC och PEFC i Sydsverige
Nature conservation on certified small private forest owners- a comparison
between the two certification systems FSC and PEFC in southern Sweden
Today two different certification systems are used in Sweden to certify forest, FSC (Forest Stewardship Council) and PEFC (Pan European Forest Certification). During the last years certification of forests in general and different certification systems have frequently been debated. FSC is a globally widespread system and about 10 million ha out of 23 million ha Swedish forest is FSC-certified. The FSC-standard is mainly used by major forest companies and to some extent also by smaller private forest owners. PEFC is a European system and about 2 million ha Swedish forests is PEFC-certified today.
Krav och önskemål på skogsbruksplanen : förbättringspotential med laserskanning
In 2009 The National Land Survey of Sweden, Lantmäteriet, commenced a project intended to provide a new digital elevation model (DEM) of Sweden. The method chosen for the project was airborne laser scanning (ALS). In addition to information about the land surface the project will also provide information about the forest, this as a by-product. This data can be used to estimate forest variables such as height and volume. The estimates are often more reliable than what is standard today.
This study is based on interviews with employees and members of the forest owner association Södra in southern Sweden.
Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier
This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.
Naturvårdshänsyn i boreal bruksskog : En studie om avverkningar och avverkare i skogarna runt Saxdalen i södra Dalarna
As the past century?s technological development has progressed the Swedish boreal forests have transformed into dense, highly productive, homogenous and coniferous forests. The area around Saxdalen in Ludvika municipality has long been dominated forests which have been heavily worked since the 18th century. There are in Ludvika 119 000 hectares of productive forest land. Around 70 percent are owned by forest companies and 20 by private forest owners.

Tjänstemarknadsföring inom fastighetsförmedling : en studie av Fastighetsbyråns förmedling av lantbruksfastigheter
Services, no matter if they are established on the market or not, are often problematic since they are difficult to define for the customer. An example of such services is an real estate agent offers his or her service when it comes to all types of real estate. The purpose of the intermediation is to sell a costumers real estate to a buyer and act arbitrator between the two parties, this means that good communication is very important. To pin down what the service is all about and to know how to communicate is essential. When it comes to land and forest holding a special need of knowledge and experience is needed to be able to act professionally.
Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog
During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today. The boreal forest is representing a carbon sink and a buffert for the emissions that occurs. Changes in this ecosystem will for that reason contribute to major impact for the global carbon cycle. To study the impact of how elevated soil temperatures affects different processes in a plantation of Sitka spruce, studies were made on the photosynthesis of the trees and the respiration from the soil.
The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation
The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours.
In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
Skogsmarksgödsling : en ekonomisk analys av olika gödslingsstrategier för ett skogsinnehav i norra Sverige
The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization.
The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.
Mellanskogs medlemmars syn på röjning
The main purpose of this study is to investigate the needs of pre-commercial thinning on private owned forest properties, which is considered to be increasing. The reason is believed to be the high cost of labor that pre-commercial thinning brings. Furthermore thinning is costly, the revenue created through pre-commercial thinning are post-poned until the first thinning.
The study was made through a survey among members of Mellanskog forest owners association. The survey was distributed by e-mail. The time to answer was set to two weeks.
The answers indicate that the most common reason why the pre-commercial thinning is delayed, or not done at all, is the forest owner?s lack of time.
