Better decisions in forest management with the SorSim bucking simulator To be able to estimate the commercial wood assortment of forests at all times is an important requirement of economical wood production. This makes it possible to improve management decisions by quantifying the revenues of alternative silvicultural and bucking strategies. So far a functional simulaton instrument for bucking single trees and whole stands was missing in forestry and in forest science in Switzerland. The SorSim bucking simulator of the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) fills this gap. SorSim is implemented in Java and is platform-independent. An overview is given how the simulator works. Two examples show applications in practice and science. Of particular value is the possibility of estimating wood assortments of planned harvesting operations based on simple timber marking protocols. Especially in science and in strategic planning, SorSim allows the analysis of the long-term development of revenues of forest stands given different silvicultural methods. Combining SorSim with IT-based harvesting productivity models provides greater insight. Further development of SorSim entails testing different optimization approaches, e.g. single tree bucking to value and whole stand bucking to order.

Since 1996, the Swiss Federal Institute for Forest Snow and Landscape Research (WSL) has been using a field computer for vegetation releves. A database and a vegetation releve program (Tally) were specifically developed for this purpose. The field computer is particularly recommended for extensive and long-term vegetation projects, as the data quality is continuously verified by plausibility tests during the process of entering data into the computer.

Between 1995 and 2008 the granting of the Binding Forest Award led to fresh cooperation between forest owners and research on silviculture, growth and yield at the Swiss Federal Institute for Forest, Snow and Landscape Research. Various topics were treated: a study of the beech coppices in Rothenfluh rapidly made it clear that very little was known about this formerly widespread type of forest management and its consequences. The same was true to a lesser extent for the conversion of rather uniform high forest into selection forest (in Plasselb), and for the selective management of light demanding tree species, such as the oak, in Rheinau. In Boudry, cooperation between practice and research already existed: the prize award here led to new approaches in the production of high quality oak, whilst taking ecological values into account. All these new projects are still in their earliest stages and will call for a great deal of “sustainability”, in both senses of the word, from all those involved. Considering the long periods of time required for the development of forest ecosystems, this is in fact self-evident.

The article considers strategic planning practices in Russia since the transition to market economy. The authors assess the outcomes of federal strategies and the possible causes of their incomplete implementation. The study reviews the development of legislation on strategic planning and the problems and contradictions associated with the implementation of the laws, including the subfederal level. The course of development of the project format of strategic documents (national projects, etc.) and the reasons that led to the strengthening of its role, despite the lack of legislative registration, are also presented. Based on the results of the review, a characteristic is given of the current state of the strategic planning system, which is assessed as unstable and transitional, and possible directions for its further development are noted. The interest in strategic planning over the past three decades has been generated by objective long-term challenges. They are largely due to the need to take into account long-term trends in demographic, technological, environmental, climatic, spatial, infrastructural, geopolitical and other areas where there are problems and tasks that can only be solved by coordinated planning of actions for many years to come.

Extension is a multi-faceted learning discipline. It is a process that works with people and the best available science and information to achieve a desired change. While science and technology provide information and tools to support sustainable development, it is the extension of this knowledge to those who must make decisions that enables innovation and sustainable forest management. There are many attempts at improving the links between the forest science and technology community, and the forest policy and management communities. It is time to make a long-term investment in forestry extension infrastructure to enable a science and knowledge-based innovative sector. Key words: extension, sustainable forest management, science and technology, information management, knowledge management

The Swiss Federal Institute for Forest, Snow and Landscape Research WSL, holds several historical collections of images related to forestry and forests in Switzerland. A majority of the photographs, negatives and slides in the collections are stored on glass plates. The archives also contain some paper copies and special thematic sub-collections on cardboard. This contribution describes various aspects of forest images dating from the first half of the 20th century. A photograph of a wood pasture taken by Hermann Knuchel (1884–1964) near the village Sufers, Canton Grisons, in June 1913 serves as a starting point.
