Ground vegetation is a powerful bio-indicator of the environment. The project aims at discriminating the various factors which may influence the dynamics of ground vegetation. Emphasis is being given to the role of nitrogen.
The Leaf Area Index (LAI) is derived from these same hemispherical photographs and
Spring keeps getting earlier, but the timing of leaf fall in autumn is more of a mystery. A new study reveals the pivotal role of the summer solstice.
This is the first time a study was able to detect both effects at the same time.
Wir untersuchen die Einflüsse umweltbedingter Stressfaktoren auf die Holzanatomie und die physiologischen Prozesse von Bäumen.

Wir engagieren und vorwiegend in der Erfassung, Analyse, Bewertung und Entwicklungsprognosen der Ressourcen des Waldes.
Then, we developed models using the same soil predictors, but extracted from digital
Wir veröffentlichen die Ergebnisse der Sanasilva-Inventur jeweils im Jahrbuch Wald und Holz des BAFU und in europäischen Berichten.

The goal of this project is to overcome these shortcomings by investigating the hydrological and mechanical conditions beneath a till-bedded glacier with physical experiments.
At the same time, water is allowed to flow along the till-ice boundary.
It is important to have good information on the condition of the trees in the plots. Therefore scientists determine the relationships between crown condition and a number of environmental parameters.
At the same time, assessing the crown condition of trees in the LWF plots provides
Supraglacial debris considerably alters the response of glaciers to changes in climate, yet debris-covered glaciers are notoriously difficult to delineate due to their fuzzy boundaries and spectral similarities to marginal moraines. Their surfaces are often characterized by supraglacial ponds and ex

An Unmanned Aerial Vehicle UAV equipped with a LiDAR sensor will be used to test its potential for regeneration structure assessments in mountain forests. The project aims to combine terrestrial regeneration mapping with LiDAR-based information to assess size, density and location of regeneration.
Field surveys of the same parameters will be conducted in the training areas (step
