Long-term vegetation change in calcareous grasslands (1997-2003)
Nutrient-poor calcareous pastures and meadows (Mesobromion) in the Swiss Jura are a heritage of traditional farming. Fifty year of tradition in their study enabled us to evaluate their areal decline and floristic change by revisitation. We studied causes and consequences of the decline in species diversity in this grassland, we set monitoring program for endangered species. Actually we explored the natural recolonisation potential of calcareous grassland species after extinctions of local populations.
