Kočí, M. et al.

Table 2. Associations recognized in the expert-based classification (Kočí 2001) and their Cocktail definitions in terms of occurrence

of species groups and dominance of species. In the Cocktail definitions, species groups are printed in bold and dominant species in

normal letters. Brief descriptions of associations are found in App. 1

Table 3. Relationships between the associations of the expert-based classification and of the formalized classification. Only relevés

assigned by the Cocktail definitions are considered in the formally defined associations. The associations of the two classifications

are compared by the phi coefficient (multiplied by 100); negative 

Φ values are not shown and values higher than 50 are printed in

bold. Numbers of associations are the same as in Table 2.
