Skottbetning på granplantor i Kolmården : omfattning och påverkande faktorer
In the Kolmården area, northeast of Norrköping in south-central Sweden, it was discovered that shoots of spruce Picea abies, plants to a seemingly large extent had been browsed by deer. The area inhabits a dense red deer population, alongside with moose and roe deer, and red deer is thus suspected to cause the damage. The main purposes of this study are, however, to estimate the extent of the shoot-damage and to investigate what factors that may affect the browsing of shoots.
For each stand information was recorded about the age of the plants, area for the stand, height over the sea for the stand, site productivity, type of plants and stand-history.
The study was done in three areas: Simonstorp, Stavsjö and Valinge. At Simonstorp and Stavsjö, respectively, 10 stands were chosen for study and on Valinge six stands. In each stand, 10 plots were sampled.
Hägn i skogsbruket :
This survey was made during the autumn of 2002 and the beginning of 2003, on commission
from the National Board of Forestry. The purpose with the survey was to gather experience
and knowledge in the organisation about fencing and this was made through interviews. The
ambition was also to get knowledge from people outside the organisation that have great
experience of forestry and fencing.
The interviews were based on questions that have been composed by the author with help
from the supervisors. The questions were the same to both the personal from the National
Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors.
The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals.
The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.
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 private forest owners are relatively satisfied with the forest management plans and with the measures proposed. There are some differences between those who live on or near their property and those who live many miles away.
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..

Stormskador i lärk och gran : en jämförelse efter stormen Gudrun
The storm Gudrun January 8-9 2005 felled about 70 millions cubic metres forest in southern Sweden. The majority of the wind damaged forest was spruce (Picea abies). In order to decrease the risk of wind damages in the future other trees species are of interest for forestry in southern Sweden.
The purpose of this master thesis was to study if larch were more wind tolerant than spruce. The method was to compare larch, Japanese larch (Larix kaempferi Lamb.), European larch (L.

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.
Markägares val av skogspartner :
Derome Skog AB is a purchase company whose main task is to provide Derome Timber's sawmills in Halland with timber raw material. Because of the very hard competition in the roundwood market it is important to know what kind of purchase offers are required in order to buy a valuable product from forest owners.This study aims to elucidate the crucial factors when private forest owners choose to harvest and sell their forest. As base for this study, a questionnaire has been performed with private forest owners. The result of the study shows that it is not particularly often that the timber price is the crucial factor why the forest owners choose to harvest and sell the forest products; i.e. timber, pulpwood as well as energy assortments.
Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden
The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.
