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.

Impact of browsing on tree regeneration
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.

Swiss National Forest Inventory NFI
National Forest Inventory NFI

What does the Swiss forest look like and how does it change over time? The Swiss National Forest Inventory (NFI) tries to answer these questions.

Project Datacenter Nature and Landscape (DNL)
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.

KLIWAWA - Verbesserung der Klimaabhängigkeit der Wachstumsfunktion für Szenarienanalysen der Waldentwicklung (Holznutzungspotential, Nachhaltigkeit)
KLIWAWA

Die Schweizer Waldwirtschaft wird wegen dem Klimawandel mit veränderten Wachstumsverhältnissen im Wald konfrontiert. In diesem Projekt sollen verbesserte Beschreibungen der Umweltabhängigkeiten für die Modellierung des Baum- und Bestandeswachstums hergeleitet werden. Der Einfluss von Temperatur, Niederschlag und Stickstoff auf das Wachstum wird mittels vorhandener Datengrundlagen analysiert, voneinander und von weiteren Einflüssen separiert, und Abhängigkeitsfunktionen für Waldwachstumsmodelle werden erarbeitet.

Versuchspflanzungen mit sechs Gastbaumarten
Gastbaumarten

Bei uns nicht heimische Baumarten, welche an ein wärmeres und trockeneres Klima angepasst sind, könnten zur Bewältigung des Klimawandels beitragen. Sechs solche «Gastbaumarten» werden in einem Langzeitversuch bei Mutrux (VD) getestet.

Forest management using the group selection system
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.

MOBSTRAT: Timber mobilisation strategies for Swiss forests
Mobstrat

The potential of Swiss timber as a renewable resource is not being fully exploited today. Mobilizing timber must, however, not jeopardize important values such as biodiversity or protection against natural hazards. Mobilization strategies need therefore careful evaluation.

Adaptive genetic variation of Norway spruce, silver fir, and beech
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.
