| Résumé : |
Centuries of summer pastoralism in the Alps have created grassland habitats which are among the most species-rich in Europe. Summer pastures provide a number of services to farmers and society, for example fodder, biodiversity or openness of the landscape. Our aim was to quantify two primary services: production of fodder for grazing animals and biodiversity in terms of plant species richness. In 2010, we measured biomass production and plant species richness at 54 sites on 6 summer farms in two regions of Switzerland. Sites were selected in order to represent a large range of topographic positions and distances from farm buildings. Vegetation was characterised using the phytosiciological classification developed Dietl for yield estimation and management planning. In addition, a dataset of 382 archival records was classified into Dietl vegetation types. We found an overall hump-shaped productivity and species richness, in which each summer farm is individually positioned, according to the vegetation groups present. Despite considerable variation in species richness within vegetation groups, the Dietl system has potential to assess ecosystem services other than biomass production, for which it was developed. |
