Time Required

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.

Further Development

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.

The Village

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.

The Impact

The research carried out by the Section of Landscape and Society at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) deals with the interaction between landscape and society. To date, the following aspects have been studied: (1) the public perception and opinion of developments in nature, landscape and environment, (2) the public perception and opinion of scientific debate on such developments,and (3) social action as a result of these developments. Striving for detailed understanding of these interactions, the methods used were based on techniques of qualitative social research. One research project examined the impact that model experiments on ecosystems had on public environmental discussion. Future research will concentrate on the following aspects of society-landscape-interaction: (1) to what extent the «needs» of the countryside are being met in areas intended for everyday and recreational use, (2) how decisions taken on a global/national level are being implemented at a local/regional, and (3) cultural and regional variations.

Structure Diversity

As in many parts of the Swiss Central Plateau, vast coppices with standards have grown in the region of Diessenhofen for centuries. While in other parts of the first decades of the 20th century the forests were converted to areas of forest regeneration species, the foresters of the Diessenhofen region altered numerous pillaged coppices with standards to a stratified continuous forest. The advantages of this form of management such as species and structure diversity and lower costs in comparison with the forest stratified by age are being presented. Each of the four foresters in the region has formed different stand images through his personal intervention intensity. There are different ways possible for achieving a continuous forest, in order to prove this, differences of managing a selection forest system are carried out by the four regional foresters. After decades of experience in tending stands established out of former coppices with standards, the approach of converting plenter forests from existing forests stratified by age to stratified continuous forests is experienced. The successes also encouraged the foresters of the neighbouring district Steckborn to do the same. This creative task is being accompanied scientifically by the WSL (Federal Institute of Forest, Snow and Landscape Research, Birmensdorf, Switzerland), which has established permanent observation areas. The steps in the previously intuitive procedure can, therefore, now be traced.
