The NISM-database (GIVD ID EU-CH-004) contains bryophyte records from 1,237 relevés of 100 m². 408 of these relevés are located on a systematic grid which covers the whole of Switzerland and Liechtenstein (1 relevé). Further 430 plots have been placed randomly (429 in CH, 1 in LI) and 399 plots have been positioned arbitrarily into different habitat types (387 in CH, 12 in LI). On each plot all bryophyte species present were recorded. For each species on each plot the main substrate where the species was growing has been noted as well as their fertility. In total, the database contains 19,000 records from these relevés. At the moment we are just starting to analyse the data, but joint projects with other working groups are welcome.
