Metod för inventering av underhållsbehov för skogsdiken

Large areas have been ditched in Sweden during the past 100 years to improve the forest production. Ditching and also maintenance of old ditches are operations having mainly negative effects on water quality, flora and fauna and changing characteristics of soil. The purpose of this study was to suggest a method for inventory of the need for ditching maintenance in old forest ditches that takes biodiversity, water protection and forest production into consideration. Inventory methods from five Swedish and Finnish forest companies, agencies and organisations were compared. Their employees were interviewed about their handling with ditches, forest production and nature conservation.

Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

Kommuninvånarnas syn på Sala kommuns skogar och skogsbruk

The municipal forests of Sala cover an area of 6 000 hectares, starting in the vicinity of the city and reaching north. At the same time as residents make abundant use of the areas closest to the community for outdoor activities and recreational purposes, the forest is of great economic value and also worth protecting for environmental reasons. These conditions make forestry in periurban woods more complex than conventional forestry, why a good understanding of the needs and demands on the forest and silviculture program is required. The purpose of this study is to depict the usage of the forests owned by the municipality of Sala, to set forth the common view of the silviculture program implemented by the municipality and to chart the expectations the community has on the forests and forestry of the future in the municipality of Sala. The survey part of this paper consists of the interviews of thirteen individuals representing nine interest groups. As expected the views of these individuals varied widely but some results were expressed by more or less all of them.

Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet

This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.

En utredning om effekterna av Skogsstyrelsens röjningsrådgivning

This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed. In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.

Hur väl skogsägare följer åtgärdsförslagen i skogsbruksplanen : en enkätundersökning

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..

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.
