Table 10: Number of species of each conservation status according to the Swiss Red List with positive, weighted-mean associations (in late summer/autumn) to each littoral habitat type. ‘Proportion’ represents the number of positive species associations to the habitat type as a proportion of the number of species occurring in lakes where the habitat was sampled. Numbers in the table differ from associations shown in Figure 17 as the latter was restricted to species recorded in the littoral zone in at least three lakes. Note that species that do not occur in the littoral zone are not included in this analysis.
