Forest Resources and Management

Main menu

The Research Unit (RU) Forest Resources and Management is principally engaged in four research themes:

Monitoring, analysis, assessment and prognosis of forest resources
Silvicultural interventions to ensure the provision of forest products and services
Availability and optimized utilisation of forest resources, especially timber
Development of methods and models related to the three research themes mentioned previously

Among the forest resources, the RU focuses its research on timber and carbon sequestration. Moreover, it provides contributions to protection from natural hazards and to the forest as habitat and recreational area, by covering forest structures and their development.

Although the RU focuses on forests, it also deals with the interaction between forests and other landscape elements. The RU handles its research themes on different spatial levels: from the stand, to the forest enterprise, to the region and up to the national level. Its research has a strong international reach, especially regarding the methods.

The RU administers the major project Swiss National Forest Inventory LFI and executes it by statutory mandate and in co-operation with the Federal Office of the Environment FOEN. Substantial parts of the LFI are carried out within the RU, while other parts are processed in co-operation with other RUs.

Methodically the RU excels at its emphasis on a solid empirical basis and on technologies needed to acquire the necessary data, especially in the fields of data collection, data management, data retrieval and data analysis. Parts of the data series concerning forest structure from the LFI, from growth and yield research and from forest reserves, surveyed over many decades, are worldwide unrivaled. These form the bases for modelling and prognoses. The methodological development of the RU focuses on statistical methods (sampling theory and time series analysis, spatial data analysis), information sciences and technologies (inventory techniques, navigation, data management, GIS) as well as simulation and decision models and their implementation in tools (expert systems as decision supports).

The RU is active in knowledge transfer. Its research projects are usually application-relevant and have an implementation component.

Tea bag decomposition study

Decomposition of plant litter is a key process for the transfer of carbon and nutrients in ecosystems. Carbon contained in the decaying biomass is released to the atmosphere as respired CO2, and may contribute to global warming. Litterbag studies have been used to improve our knowledge of the drivers of litter decomposition, but they lack comparability because litter quality is plant species-specific. The use of commercial tea bags as a standard substrate was suggested in order to harmonize studies, where green tea and rooibos represent more labile and more recalcitrant C compounds as surrogates of local litter.

Herb layer biomass in Swiss forests

The Swiss national forest inventory (NFI) provides comprehensive information on the state of forests in Switzerland. The purpose of this project was to develop a model to estimate herb layer biomass and carbon stock based on the categorical cover estimate on each NFI sample plot.

Vegetation height model NFI

For Switzerland, a national vegetation elevation model was calculated and updated on an ongoing basis. The ADS80 images routinely captured by swisstopo form the basis for the image matching workflow for deriving a 3D model of the landscape.

Agent-based Modelling

Agent-based modelling enables to model all actors on the wood market individually. Simulating the model then provides insights into the market processes. With the simulation of various scenarios, the effects of structural and institutional changes on the wood market should be explored. The project is part of the WSL-project “An economic analysis of Swiss wood markets”, which is connected to the NRP 66 program “resource wood”.

An Economic Analysis of Swiss Wood Markets

In this project, researchers analyse the workings of the Swiss wood markets on the basis of case studies and explain them with the help of economic theories. The results will be used to develop an agent-based model. This should make it possible to develop scenarios for future wood availability and present options for influencing it through economic instruments.

Soils and water regime of Swiss forests

For the whole forest area of Switzerland, we will map soil properties that are relevant for the water regime of forest stands. Based on this data we will run a water balance model for the 6000 plots of the National Forest Inventory (NFI) from 1980 to 2100 in order to detect regions that likely will suffer under increased drought in the near future.

Sortimentsimulator SorSim

SorSim ist ein Computer-basiertes Modell, um einzelne Bäume oder ganze Bestände in Sortimente einzuteilen. Die Schaftformen werden modelliert, Rinde und Zumasse werden abgezogen und aufgrund von Sortimentsvorgaben in die entsprechenden Klassen eingeteilt.

Forest and climate

An expansion of forested zones could bring about a warming of the atmosphere at higher altitudes.

Update HeProMo

The productivity models "HeProMo", realized in 2003, are partially going to be outdated and several models for new modern harvesting processes are missing yet. The aims of the project are to renew some of the existing models based on new data sets and to create new models for current harvesting processes, such as logging and chipping of energy wood, transport of chips and logging of full trees by cable-crane.

Impact of browsing

Tree regeneration is part of the normal diet of ungulates species such as roe and red deer and chamois. Silver fir and sycamore maple are particularly preferred tree species for ungulate browsing, but also silvicultural important tree species. Analyses of data from long-term surveys in indicator areas are used to determine whether and how ungulate browsing affect the structure of regeneration in the long term, i.e. the size distribution of the tree species.

Exotic tree species

Exotic tree species, which are adapted to a warmer and dryer climate, could contribute to coping with climate change. Six such species are tested in a long-term field experiment near Mutrux (Canton of Vaud).

Nadelbäume und Trockenheit

Sehr starke waldbauliche Eingriffe im Gebirgswald können kurzfristig ökonomisch vorteilhaft sein. Langfristig könnten sie aber die Waldverjüngung verzögern und den Holzuwachs vermindern. Ob solche nachteiligen Auswirkungen auftreten und wie gross sie allenfalls sind, wird mit retrospektiven ertragskundlichen und dendroökologischen Erhebungen in Gebirgswäldern abgeschätzt.

Genetic Variation

Die Klimerwärmung dürfte den Wald auf vielen Standorten unter Stress setzen. Wir untersuchen, ob die genetische Variation der Waldbäume es ihnen erlaubt, sich an den Klimawandel anzupassen. Wir fokussieren dabei auf die drei häufigsten Baumarten in Schweizer Wäldern, die Fichte, die Tanne und die Buche.

Dynamics of dead wood and saproxylic insects

Dead wood is a vital prerequisite for a quarter of all organisms living in a forest. The future intensification of forest management will pose a threat to many wood inhabiting (saproxylic) insect species. In forest reserves the formation and decay process of dead wood is quantified and the importance of micro-habitats for saproxylic beetles is investigated.

Auswertungssoftware NAFIDAS

Die NAFIDAS Auswertungssoftware ermöglicht konsistente und verlässliche Berichte mittels Daten des Schweizerischen Landesforstinventars LFI in Form von Tabellen und Karten.

The data analysis system NAFIDAS

The national forest inventory data analysis system (NAFIDAS) allows producing reliable tabular reports using data of the Swiss national forest inventory (NFI) and involved cantons.

Physical soil protection

Soils fulfill various functions. As a consequence of land cultivation and of the emission of harmful substances from various sources, the soil functions are endangered. In the research topic “soil protection” the main threats and their effects on the soil functions and hence on soil fertility are investigated.

Young growth tending

Each year, about 50 Millions CHF are invested in tending interventions in Swiss forestry. In a field experiment of 7.3 ha size, we study how four tending variants affect tree species richness and stem quality in the long term. Particular interest is given to the question how minority species present in mixed stands can be maintained against the highly competitive beech.

Group planting

After large-scale storm damage, the density of seedlings from natural regeneration is sometimes insufficient. In such cases, planting is justified. The cost-effective establishment of such plantations, and in particular the planting in small groups, is the focus of this project.

Regional inventories using the NFI method

The WSL offers support of regional (cantonal) inventories based on the Swiss NFI method as a service in collaboration with the cantons.

Datacenter DNL

The purpose of the project DNL is to integrate existing national biotope inventories (bogs, flood plains, meadows, etc.) into a database and connect it to further datasources of the FOEN. Particularly the lineage of the data with all scientific and political processes shall be documented.

The group selection system

The effects of selective thinning and group selection cuts on stand growth and stability are studied in this long-term project. The aim is to derive silvicultural recommendations for risk reduction in mountain forests.
