Each boulder usually hosts from half a dozen to a dozen species – most of them common, of course, but there is interesting stuff among them sometimes. Boulders are different in origin – sometimes you can find dolomite, granite, quartzite and others all along the same road. That helps to get more diversity of lichen species in the same location. So it’s somewhat artificial, since those boulders don’t belong in that location – they were brought from somewhere else. But I believe most of the lichen were not brought with the boulders but developed on site.
