Changes in land use and climatic variation affect semi-natural meadows.
We are interested in the variability of structure and productivity
across time and the mechanisms by which plant species with different
life history traits regenerate and maintain species rich communities.
Our observations and experiments are based on measurements in the
field. Three long-term study sites are located in the Southern Alps.
We run complementary studies on soil seed banks and growth of seedlings
from different origin in a laboratory in the Botanical Garden Bern.
Throughout Europe changes in land use have affected the plant species composition
of meadows. This has led to an increased interest in processes which allow many
species to regenerate and maintain species-rich meadows.
During a period of 10 years, from 1988 to 1997, we monitored the species composition
in dry grasslands of high species richness at experimental sites in the ‘lower
montane zone’ of the southern Alps in Switzerland.
