In Switzerland dry grasslands belong to the endangered biotopes. As a part of the federal inventory of dry grasslands of national importance, this project dealt with the question which factors influence the farmers' decision to sign a management contract for dry grassland. The results show that apart from financial reasons several other factors are relevant. These factors cannot be ranked because every single farmer places the importance differently. However it is obvious that the relevance of a factor strongly depends on the kind of production the farm is set up for.
