Table 1.
Epiphytic lichen species observed in this study and their probability of occurrence on a certain host tree species as well as on a tree in average.
Fig 1.
Tree level epiphytic lichen richness (alpha diversity) per tree species with medians and 95% credible intervals.
The horizontal lines in the background shows averages across tree species. Complete pairwise comparisons are in Table 2.

Table 2.
The results of the pairwise comparison of the lichen richness on the different tree species (comparable to an ANOVA).
Fig 2.
Stand level beta and gamma diversity is modelled with the number of tree species in a subplot.
The predictions are the median together with the 95% credible intervals. Higher tree species richness was in all pairwise comparisons associated with higher lichen diversity with a posterior probability of 95%.

Fig 3.
a) Stand level beta and gamma diversity is predicted with the percentages of Norway spruce, Scot’s pine or deciduous trees on a stand. This was done with three separate models but they are here combined for visual comparison (e.g. at 40% spruce nothing can be said about po9the tree species composition of the remaining 60% of the trees). The predictions are medians with the 95% credible intervals. The probability densities of the percentage of a tree species which is expected to result in the highest number of lichen species is presented above for all tree species groups. b) Ternary plot with the percentages of the tree species groups as the axis. The colours show predicted beta and gamma diversity for the tree species percentages that occurred on the studied subplots.
