The project will make use of large phytosociological database and recently developed computer-based methods of formalized vegetation classification for making a survey of the semi-natural grasslands of the Czech Republic. The main classification algorithm will be COCKTAIL (Bruelheide 1995), as implemented in software package JUICE (Tichy 2001). This approach will yield a classification which has clearly defined classification criteria and is close to the traditional phytosociological approach. The numerical classification will be supervised by experts in order to achieve a compromise between formal definition and practical applicability of the vegetation units. Vegetation units distinguished will be parametrized by the values of measured environmental variables, indicator values and using GIS overlays. Each vegetation unit will be documented by synoptic tables and distribution maps. Diagnostic, constant and dominant species will be defined by formal numerical algorithms. The output of th
