The plant composition of extensively managed hay meadows was investigated in a sample which is representative for the Swiss plateau. In 1401 relevés 511 species were recorded. 17 species figure in the national red list and 70 species have regional red list status. 25 % of meadows contain a minimum set of characteristic plants of species rich meadows, but only 7 % belong to a category of traditionally managed grasslands.
