For each species, the fraction of plots at which it was found (i.e. the number of plots where this species was found divided by the total number of plots) is shown.
*p-value of Fisher’s exact test. Species witht p-value < 0.05 after Bonferroni correction for multiple testing are in bold. Species for which the p-value was significant only before the correction are underlined.
**Preferred site according to Fisher’s exact test; n.s.—test is insignificant. H—microhighs. L—microlows. Dash—plant species did not occur at the key site.
