Abstract

Saxicolous lichen vegetation on Ordovician rock at the mouth of the River Dovey, South Merionethshire, is examined in relation to aspect, slope angle, light intensity, rock porosity, rock microtopography and rock stability. A number of characteristic groups of species are recognized. The environmental factors measured are discussed in some detail. In addition, the wide tolerance of most saxicolous species is emphasized.
