Abstract

The mechanisms for the connection between soil and bark chemistry are unknown, but several explanations can be postulated, of which an impact from the soil on the bark through transportation of nutrients from the tree roots to the bark seems the most likely. Since bark chemical factors are important for epiphytic species, soil properties might affect the composition of the epiphytic vegetation on Populus tremula. There is a need to investigate further the bark-soil relationships and the mechanisms of possible interactions. If the epiphytic species are indirectly affected by the soil through influences on the bark, this could have consequences for conservation management intended to preserve epiphytic species as well as for the use of bryophytes and lichens as indicators of air pollution.
