Abstract: 7 fig. 2 tab. ["The moraine studied, roughly 34 years old, was in an early stage of plant succession. Plant communities were observed only on the boulders at the top of the moraine. They were always composed of a relatively small number of lichen species and with a low coverage of the rock surface."]
