Irrigation Experiment Pfynwald
Irrigation Experiment Pfynwald

Drought-induced forest decline will gain in importance as the frequency and severity of drought events are expected to increase in the context of climate change. To understand how chronic drought affects tree growth, we study mature Scots pine in an irrigation experiment in an inner-Alpine dry valley since 2003.

TreeMig: modelling spatio-temporal forest dynamics from stand to continental scale

A spatio-temporal forest modelled has been developed to simulate forest dynamics and species migration under a changing climate.

Tending measures in the mixed broadleaved forest Buechberg, Diessenhofen
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.

Changes in subalpine spruce forests under the impact of climate change – a case study in Bulgaria
Bulgarische Bergwälder

In large uncultivated forests in Bulgaria, the SLF is investigating the potential reaction of mountain woodland to climate change.

PMSoil: Predictive mapping of soil properties for the evaluation of soil functions at regional scale
Digital Soil Mapping

The project aims to develop the methodological basis for creating high-resolution maps of soil properties using digital soil mapping methods and for converting such information in a standardized way to soil function maps.

Quality wood production from chestnut (Castanea sativa) coppice sands
Quality wood production

In 1998, the Italian Institutions as the Forestry Research Center of Arezzo CRA-SEL, the TESAF Department of Padova University and the Swiss Federal Research Institute WSL, initiated a common research program aiming at the definition of silvicultural approaches for the production of high quality chestnut timber by minimizing the costs and improving the functional features and the stability of the coppice stands.

Research and effectiveness controlling in Swiss forest reserves
Forest reserves

Most Swiss forests are managed. However, some forests are protected as reserves, in which nature can develop within human interference. Fifty years of research in these reserves shows that the naturalness of these forests increases.

Derivation of characteristics for the evaluation of game impact on tree regeneration
Characteristics of game impact

The relationship between the brwosing intensity and structure of the tree regeneration is complex. In this project, knowlege gaps in the characteristics to evaluate the influence of game will be explored by means of further investigations in indicator areas in the canton of St. Gallen and the potential additional features will be tested form foresters for their practicality in the region Calanda. The aim is to approach a scientifically sound and at the same simple monitoring for game influence on forest regeneration.

Developing an efficient forest inventory on forest enterprise level
Forest inventory on enterprise level

The hitherto existing methods for forest inventories on forest enterprise level as the basis for forestry planning and controlling are time consuming and expensive. With a smart combination of data collected with terrestrial methods (sample plots, stand descriptions) and remote sensing (aerial photos, LIDAR, etc) forest inventories shall become more efficient and practice oriented to serve the needs of a multifunctional forest management. This combination shall be implemented in software tools (prototypes), which shall lead to planning tools for forest managers.
