In this WSL Biodiversity Centre Postdoc project, we will investigate the relationships between woody encroachment, habitat diversity and plant species diversity. Modelled vegetation height based on historical aerial stereo images, covering 40 years of woody encroachment and forest expansion, will be combined with existing biodiversity data. This allows for a spatially explicit assessment of the relationship between woody encroachment and the dynamics of habitat and plant species diversity.

Ungulate browsing is an important driver of forest regeneration in mountain protective forests of the Valle Mesocina.

This ETH-Domain ORD Program Contribute Project aims at curating and uploading the existing data of the European Long-term treeline Ecosystem Research (eLTER) site Stillberg, Switzerland, was established in to national and international ORD platforms (EnviDat, DEIMS-SDR).

The Long-Term Ecologiocal Research in Europe (LTER-Europe) capitalizes on research infrastructures such as the in-situ network of sites and information technology. Thousands of research projects have been carried out taking advantage of this infrastructure.

We investigate seedling emergence and survival of Norway spruce and European larch at treeline in an experiment at Stillberg near Davos.

Temperature in Arctic and alpine regions have increased more rapidly than in other regions. How do tundra ecosystems respond to that climate warming? The SLF is contributing to an international research network that studies at over 40 locations worldwide how cold adapted plants respond to warmer temperatures.

The project examines how warmer winters and hot-dry summers affect the growth of potential future tree species during the advanced regeneration stage and how this response is modulated by soil properties and soil biotic communities.
