Drivers of lichen species richness at multiple spatial scales in temperate forests
Only few studies analysing lichen diversity have simultaneously considered
interactions among drivers that operate at different spatial and temporal scales.
Aims: The aims of this study were to evaluate the relative importance of host tree, and local,
landscape and historical factors in explaining lichen diversity in managed temperate forests, and
to test the potential interactions among factors acting at different spatial scales.
Methods: Thirty-five stands were selected in the ĆrsĂ©g region, western Hungary. Linear models
and multi-model inference within an information-theory framework were used to evaluate the
role of different variables on lichen species richness.
Results: Drivers at multiple spatial scales contributed to shaping lichen species richness both at
the tree and plot levels. Tree level species richness was related to both tree and plot level
factors. With increasing relative diffuse light lichen species richness increased; this effect was
stronger on higher than on lower part of the trunks. At the plot-scale, species richness was
affected by local drivers. Landscape and historical factors had no or only marginal effect.
Conclusions: Lichen conservation in temperate managed forests could be improved if the
complex interactions among host tree quality and availability, micro-climatic conditions, and
management were taken into consideration
