K. Matějka: Diversity of ecological groups of species in cultural forests of South Bohemia

Back to the paper

Table 1. A survey of measures of species diversity (S, e, H), of average indication value (i), standard deviation of indication value (σ), and ratio of indiferent species recorded in relev‚ (x%). Groups of forests constituted by the TWINSPAN procedure:

1 - acidophile cultural forests (Dicrano-Pinion),

2 - submonuntain broad-leaf forests - Genisto-Quercion (ass. Luzulo-Quercetum) and Fagion (ass. Abieto-Quercetum),
