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.

Its regulations prescribe that at least 10 wind firm trees should be left behind after every clear cutting operation.
This study have taken place on 30 recently clearcut objects in Bergslagen, Sweden, were an inventory of the standing stock have been made. The research shows that, with 90 % security, the retained trees together contain 9-13 m3sk per hectare. Pine is the dominant tree and it covers more than half the numbers of retained trees and its volume cover 65 % of the retained trees total volume. Spruce is on second place with 30 % of the retained trees, but only 21 % of the standing stock.

Hur väl skogsägare följer åtgärdsförslagen i skogsbruksplanen : en enkätundersökning
This rapport is about how often private forest owners follow the measures proposed in their forest management plan. The survey is made in cooperation with the forest-owners association Norrskog.

The forest owners who live on their property are those who follow the proposed measure of precommercial thinning to the largest extent. That group also values precommercially thinned stands higher than thinned stands.
The complete opposite is the case for the group that lives far away from their property.
Almost all of the respondents thought that the forest management plan would be or had been a good help in the decision making about the forest..

Histiocytära sjukdomar hos Berner Sennenhund :
The histiocytic diseases are generally rare in dogs and not much is known about
the disease. The disease complex that includes both a reactive form and a tumour
form, is however common in certain breeds, among them the Bernese Mountain
Dog. As the literature is very limited on the subject of histiocytic diseases, my aim
with this thesis has been to gather current knowledge of these diseases. I have also
attempted to estimate the frequency of the diseases among the Swedish Bernese
Mountain Dogs and investigate if they appear to be more common among certain
families..
Betydelsen av skogens ålder och förekomst av lavar för renars val av vinterbetesområde :
This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.
Enskilda skogsägares mål på avdelningsnivå ? en kvalitativ studie
Half of Sweden's productive forest land is owned by individual forest owners. Research studies show that forest owners have more objectives with their forest than a high net present value, and that the suggestions of the forest management plans doesn?t always correspond to
the forest owners? objectives.
Through a qualitative study we conducted a discussion about objectives at stand level with the aim of making a more specific formulation of the forest owners? objectives.
We asked about the forest owners' objectives at stand level, what forest management they conduct in order to achieve the objectives and how this management affects the net present value of the property. Based on the results of the interviews, we analyzed what kind of factors decide where the objectives place themselves in the landscape and if the objectives at stand level are consistent with the overall objectives for the property.
Many forest owners questioned the idea of talking about objectives at stand level, and they didn?t always have their objectives clearly defined.
